Best Time of Day to Fish in Guam
Guam is a region with a warm climate. It’s hot in the region in the middle of the day. That’s why fishing in the waters near Guam can be difficult during the afternoon hours. The vast majority of fish species that can be found in the local waters feed actively at dawn and at dusk.
Many fish species get active in the local waters during the morning hours. So, it would be better to go fishing in Guam early in the morning. Water cools down and the activity of fish increases in the morning.
The success of fishing in Guam also depends on tides. There is a direct link between Guam tide times and bite times. That’s why anglers should study Guam tide times before going fishing.
Fishing in Guam is best during an incoming tide. When a tide is rising, oxygen-rich water is brought to the area. As a result, the activity of fish increases in the local waters.
Fish begin to search for food and anglers can easily catch it. It’s also important to note that water is clear during an incoming tide allowing fish to better locate food.
The weather is often rainy in Guam. Rain affects fishing. Fishing in light rain can be very productive. However, fish move to deep waters and stay inactive when rain is heavy. Fish get active and bite well after a rainstorm.
Fishing during storms should be avoided for safety reasons. A fishing trip will be canceled if severe weather is expected in the region.
It would be better to reschedule a fishing trip if bad weather is expected. Storms and rains often happen in Guam from June to November.
It’s worth noting that winter fishing is less productive in the region. Many fish species are inactive in the waters near Guam at this time of the year.
However, it’s possible to go fishing during the winter months. In winter, anglers have a chance to catch jobfish, rainbow runner, roosterfish, mahi-mahi, trevally, tuna, and wahoo.
