How Weather Conditions Impact Steelhead Fishing (Guide)

Weather is one of the most crucial factors when setting off to fish for steelhead. Handling whatever conditions mother nature dishes out can help you catch more steelhead.

Steelhead adjust their activity and location in response to weather changes, becoming more active with dropping barometric pressure and seeking deeper waters during bright sunlight or warmer temperatures.

Best Weather for Steelhead Fishing

Steelhead react in different ways to the weather, which affects fishing. When the barometric pressure drops, usually before a storm, steelhead become livelier, making it a good time to fish. Rainy days can be both good and bad: a little rain might help because it gets the fish moving in rivers, but too much can turn the water muddy and they can’t see the bait.

Cloudy days are often better than sunny ones because steelhead feel safer with less light. Strong winds can push them to deeper water, making them harder to catch. Lastly, steelhead might dive deep to find cooler spots if the water’s too warm. So, for the best fishing, look for dropping pressure, light rain, and cloud cover.

Water Levels & Steelhead Fishing

River flow and water clarity are crucial factors impacting steelhead fishing and closely related to weather conditions. River flow, often measured in cubic feet per second (cfs), determines how fast the water moves.

When river flow is too high or too low, it can make it difficult for steelhead to navigate and find suitable resting spots. High flows can also push food sources away from their usual spots. On the other hand, moderate flows offer better fishing opportunities as steelhead can move more comfortably.

Water clarity, which refers to how clear or murky the water is, affects steelhead behavior and visibility. Muddy or turbid water can make it challenging for steelhead to spot lures or bait, reducing their feeding activity. Steelhead might be more cautious and easily spooked in clear water, requiring anglers to use subtle approaches.

Weather conditions such as heavy rain can increase river flow and muddy water, making fishing less favorable. Conversely, stable weather with minimal rainfall results in better river conditions, improving fishing success due to more favorable flow and clearer water.

State Breakdown of the Steelhead Strains

The Great Lakes “steelhead” are introduced fish not native to the region. They use the great lakes as their “ocean” and return to it every summer to grow bigger. Steelhead are native to the west coast and Pacific Northwest.

1. Pennsylvania (PA):
   • Strains Stocked: Primarily the London strain.
   • Run Timing: These steelhead generally enter the tributaries in the fall, overwinter in the streams, and spawn in the late winter to early spring.
2. Ohio (OH):
   • Strains Stocked: Mainly the Manistee strain.
   • Run Timing: Typically, they migrate in the fall, overwinter in the streams, and then spawn in late winter to early spring.
3. Indiana (IN):
   • Strains Stocked: Skamania strain and Chambers Creek strain.
   • Run Timing: Skamania tend to have a summer run and spawn in early fall, while Chambers Creek usually enters and spawns in the spring.
4. Michigan (MI):
   • Strains Stocked: Manistee strain, Chambers Creek, and Little Manistee.
   • Run Timing: Generally, these steelhead enter the tributaries in the fall, overwinter, and then spawn in late winter to early spring.
5. Wisconsin (WI):
   • Strains Stocked: Ganaraska strain and Chambers Creek strain.
   • Run Timing: Like others, these steelhead usually enter tributaries in the fall and spawn in the spring. The Ganaraska might have some early spring arrivals.
6. New York (NY):
   • Strains Stocked: Primarily the Washington (Chambers Creek) strain.
   • Run Timing: These steelhead often enter the tributaries in the fall, overwinter, and spawn in the late winter to early spring.
7. Ontario (ON):
   • Strains Stocked: One of the main strains has been the Ganaraska strain, though other strains might also be used.
   • Run Timing: Ganaraska steelhead typically start their run in the late winter to early spring and spawn shortly after entering the tributaries.

In the Pacific Northwest and along the west coast of North America, steelhead are native, and their runs are typically divided into “summer-run” and “winter-run” based on when adult fish migrate from the ocean to freshwater. Here’s a general breakdown:

1. Oregon (OR):
   • Strains/Types: Both summer-run and winter-run steelhead are found.
   • Run Timing: Summer-run steelhead generally enter rivers from late spring to early fall and spawn the following spring. Winter-run steelhead enter rivers in the late fall to spring and spawn shortly after that, usually in late winter to spring.
2. Washington (WA):
   • Strains/Types: Both summer-run and winter-run steelhead.
   • Run Timing: Similar to Oregon, summer-run steelhead enter from late spring to early fall and spawn in the spring. Winter-run steelhead migrate from late fall to spring and spawn in late winter to spring.
3. Alaska (AK):
   • Strains/Types: Mostly summer-run steelhead, with some areas having winter-run.
   • Run Timing: Summer-run steelhead in Alaska usually enter freshwater in late summer to early fall and spawn in spring. Winter-run timing is less prevalent and can vary, but generally, they enter in late fall to early winter and spawn in spring.
4. British Columbia (BC):
   • Strains/Types: Both summer-run and winter-run steelhead.
   • Run Timing: Summer-run steelhead typically enter from late spring to early fall and spawn in the spring. Winter-run steelhead migrate from late fall to spring and spawn in late winter to spring.
5. California (CA):
   • Strains/Types: Mostly winter-run steelhead, with some areas having summer-run.
   • Run Timing: Winter-run steelhead in California generally enter freshwater from late fall to early spring and spawn in late winter to spring. Summer-run steelhead, less common in California, enter from late spring to early fall and spawn the following spring.

Daily Weather for Steelhead Fishing

Steelhead trout fishing changes a lot with the day’s weather and time. When the barometric pressure drops, often right before a storm, steelhead become more active, making it a good time to fish. Rain can get them moving, especially in rivers, but too much rain might make the water muddy and hard to fish.

Cloudy days are great because the fish feel safer without much sunlight shining down. Strong winds might make them go to deeper water, so it can be trickier to catch them then. The early morning and late afternoon are the best times to fish, while midday, when the sun’s brightest and hottest, is usually the least productive.

Seasonal Guide

Winter

During winter, steelhead are influenced by the chilly weather conditions in rivers, either laying eggs or preparing to return to the ocean or Great Lakes. A drop in barometric pressure, often before a snowstorm, can make these fish more energetic, making it a prime time for fishing. The moon’s phases, especially full or new moons, can also affect their activity.

Snow or rain can cause rivers to rise or flow faster, making more steelhead swim upstream. Less sun on cloudy days makes steelhead bolder and less wary of bait. The wind’s direction and speed might change the water’s temperature, leading steelhead to new spots.

In the Great Lakes region, steelhead are usually in rivers throughout winter, getting ready to head back to the lakes around May. On the West Coast, they come into rivers mainly from January to April and start their ocean return by May. Early morning or late afternoon are the best times to catch them, as steelhead are more active during these cooler parts of the day.

Spring

In spring, steelhead react to many weather changes in rivers laying eggs or heading back to the ocean or Great Lakes. When barometric pressure drops, usually right before a storm, steelhead become more active.

Some anglers also believe that steelhead are extra lively around a full or new moon. Rain can make rivers flow faster, attracting more steelhead upstream. Cloudy days can be perfect for fishing because without a lot of sun, steelhead aren’t as shy. Wind can change water temperatures, which might shift where these fish hang out.

For the Great Lakes, steelhead mainly come to rivers in the fall, but by May, they start heading back to the lakes. On the West Coast, they typically come to rivers a bit earlier, from January to April, and by May, they’re often on their way back to the ocean. For the best chances to catch them, try fishing in the early morning or late afternoon when steelhead are most active.

Summer

In the summer, steelhead react to the warm weather and its effects in big water like oceans or the Great Lakes. When barometric pressure drops, usually right before a summer storm, steelhead often swim deeper where it’s cooler, which can affect fishing. The moon’s phase is important too; during full or new moons, steelhead might be more lively in the big waters.

Rainfall, even though it’s rarer in summer, can cause steelhead to search for cooler spots in deeper waters. On sunny days, steelhead usually dive deep to escape the heat and bright light. Wind can stir up the water’s surface, cooling it down and sometimes making steelhead move closer to the surface. In the Great Lakes during summer, steelhead mostly stay in the deep, cool parts of the lake.

On the West Coast, after they’ve returned to the ocean around May, they prefer cooler ocean depths. The early morning or late evening, when the sun isn’t so hot, are the best times to fish for them, as steelhead come a bit closer to the surface during these cooler times.

Fall

In the fall, steelheads react to weather elements when they swim to rivers to lay eggs or head back to the ocean or Great Lakes. A change in barometric pressure, especially a drop before a rainstorm, can make them more lively. Moon phases also play a role; steelhead might be more active during full or new moons.

Rainfall, common in the fall, can cause rivers to flow faster, pulling more steelhead upstream. Steelhead are less cautious on cloudy days without much sunlight, making it a good time to fish. Wind can affect water temperatures and currents, making steelhead move to different parts of the river.

For the Great Lakes steelhead, many start entering rivers in the fall, staying there over winter. On the West Coast, their big move into rivers is a bit later, mainly from January to April. To increase your chances of catching one, fish in the early morning or late afternoon when steelhead are most alert and active.

Locations of Steelhead & Weather

During cold months, they travel from big waters, like oceans or the Great Lakes, into rivers to lay their eggs. In winter and spring, rivers are the best spots to find them. When summer heats up, steelhead prefer the cooler, deeper waters of lakes or oceans, avoiding the warm surface. If a storm is coming and the barometric pressure drops, they get more active, and you might spot them more in rivers.

When it rains, they’re often pulled to the faster parts of a river, moving upstream with the flow. On cloudy days without a lot of sun, they feel safer making them easier to catch.

Impact of Weather on Steelhead Fishing

Weather plays a crucial role in steelhead fishing. When it’s rainy or overcast, steelhead are often more active making them easier to catch. Cold fronts can slow their activity, making them more sluggish and less likely to bite. In contrast, a warm front might increase their movement and feeding.

Water clarity is another factor influenced by weather; murky water can make steelhead less likely to see and go after lures after heavy rain. To stay cool, these fish might head to deeper waters or shaded areas on sunny days.

Water levels and clarity play a big role in steelhead fishing. When water levels rise, especially after rain, steelhead move to faster parts of a river. But if there’s too much rain, the water can become muddy, making it harder for steelhead to see bait. Clear, stable water makes steelhead more cautious.

Weather Factors: Steelhead Fishing

Air Temperature

Air temperature significantly affects steelhead behavior because it influences the temperature of the water they live in. Steelhead are most comfortable and active when air temperatures are between 40°F and 60°F.

When air temperatures get very cold, below freezing, it can cause the water to cool down too much, making the steelhead less active and harder to catch. On the flip side, if the air becomes too hot, above 70°F, the water may warm up and stress the fish, leading them to seek cooler areas.

Water Temperature

Water temperature greatly affects the behavior of steelhead. These fish are most active in water temperatures ranging from 40°F to 55°F, making this the optimal range for fishing.

When the water temperature dips below 40°F, steelhead slow down and become less active, while temperatures above 60°F can stress them, leading to them seeking cooler, deeper waters. Extremely cold or hot temperatures can also affect their feeding habits, making them more picky or less likely to bite.

Barometric Pressure

Barometric pressure, or the weight of the air, can affect steelhead’s feeding habits. When the pressure is high, steelhead might be less active and not feed as much. But when it drops, often before a storm, steelhead feed more.

During these changes in pressure, using natural baits like roe bags or flies can be very effective, as steelhead might be looking for food before the weather shifts.

Wind Speed

Wind can play a big role in steelhead fishing. Blowing wind pushes food like insects and smaller fish, to certain parts of the water, making steelhead follow and gather there. Often, an onshore wind (wind blowing from the water to the land) can be the best for fishing because it brings food towards the shoreline.

If the wind is too strong, it might make the water murky and challenging to fish. Using bait like roe bags or brightly colored lures can be helpful, especially if the wind stirs up the water and lowers water visibility.

Cloud Cover

Cloud cover can change steelhead behavior and where they swim. On overcast days, steelhead often feel more secure and may venture to shallower waters, making them easier to target. In contrast, they tend to stick to deeper waters or areas with more shade on bright days.

For bait, roe bags, jigs, and brightly colored lures are good choices. Fishing closer to the surface can be more productive on cloudier days, while on sunny days, going deeper works best.

Precipitation

Rain can increase river flow and murkiness, drawing steelhead closer to shore and making it a good time to fish. However, heavy rain might muddy the water, and fishing can be challenging. Snow can cool water temperatures, sometimes making steelhead less active.

Regardless of the weather, these fish usually eat small fish, eggs, and insects, and using roe bags, jigs, or brightly colored lures as bait can be effective, especially during light to moderate rain when steelhead are moving.

Frontal Systems

Frontal systems, like cold or warm fronts, greatly affect steelhead movement and behavior. When a cold front is approaching, steelhead tend to feed more. But after the front passes, they might become less active, staying in deeper water.

Conversely, warm fronts can make steelhead more cautious and push them to cooler areas. Steelhead are known to munch on small fish, eggs, and insects, with roe bags, jigs, and brightly colored lures being top bait choices, especially right before a front when they’re in a feeding mood.

Sunlight Intensity

Bright sunlight can cause the fish to seek shelter in deeper waters or shaded areas. This is because the clear water and intense sunlight can make them more visible to predators like eagles and ospreys. When the sun is shining strong, fish under logs or overhanging trees.

The brightness might make them picky eaters, so using natural-looking baits, like roe bags or smaller, subdued-colored lures, can be effective. They will roam more freely on cloudy days and respond better to brighter or flashier baits.

Moon Phase

Moon phases can influence steelhead behavior even during the day. When the moon is full, steelhead might be less hungry during the day because they were more active and feeding at night. This means that daytime fishing might be a bit trickier during a full moon.

On the other hand, during a new moon when nights are darker, steelhead are less active at night and might more active during the day.

Seasonal Changes

In the spring, they move from the ocean or big lakes into freshwater streams to spawn. As the warmer summer months roll in, they return to the sea. Fall can see another migration as some steelhead prepare for a winter spawn, making rivers a hotspot again.

The food they eat changes too. During their migrations, they might eat aquatic insects in spring and fall, but they’re all about schooling fish in the deep summer waters.

Breaks in Weather

Imagine if you had a hot sunny week, and suddenly a cool, rainy day comes along. Steelhead love those sudden changes and become more active.

During a cold stretch, they lay low and eat less, but as soon as it warms up, they’ll look for a meal. Their food choices shift too. On those rainy days after warmth, they might hunt more for insects that get washed into the water.

But after a cold spell, they might be craving bigger stuff like fish. For anglers, this means on those change-up days, trying a variety of baits, from insect imitations after rain to small fish lures after cold breaks, might get a steelhead’s attention.

Steelhead Spawn & How Weather Can Impact

Steelhead are special because they have different strains, and these strains spawn or lay their eggs at different times. Some steelhead strains spawn in the spring, while others do so in the fall. This means they swim up rivers at different times, depending on their strain.

Weather plays a big role in fishing for steelhead, especially in spring. When the sky’s pressure drops, steelhead become more active, which is great for fishing. Rain can help, too, because it raises the water levels and makes it cloudy, so steelhead feel safer and eat more.

Strong winds can make fishing tough, and steelhead may not feed as much. Most fishermen find that early morning and late afternoon are the best times to fish, but the middle of the day can be slower.

What Steelhead Eat & Influence Weather Has

Steelhead have a diet that can change with the weather. On sunny days, they will shy and focus more on insects like mayflies or caddisflies. But they become bolder when overcast and might go after bigger meals like schooling baitfish. In rivers, especially after rain, they feed on aquatic insects that get swept into the current.

In coastal areas, they might eat small crustaceans and fish. Use flies on sunny days, while switching to baitfish lures could be the key on cloudier days.

Matching the Bait Color to Conditions

In clear water or bright, sunny days, use more natural colors like browns, greens, or silvers. But if the water’s murky or cloudy, brighter colors like orange, pink, or chartreuse can help steelhead see your bait better.

Patterned flies with spots or stripes are also good when water is cloudy. Use smaller, natural-colored jigs and worms in clear water. In murkier conditions, larger jigs in brighter colors or baits like orange or pink skein (fish eggs) can get a steelhead’s attention.
