Grades rate solunar timing and moon phase for the whole US. Water temperature moves a fishing day more than the moon does and depends on where you fish.

Fall Fishing Tips
Fall triggers aggressive feeding as fish prepare for winter. Follow baitfish migrations and target transition zones. Cooling water pushes fish shallow again. Some of the best fishing of the year.
Best Fishing Days in September 2027
The top-rated fishing days in September 2027 are September 29, September 15, September 30, September 16, September 14, ranked by solunar activity, moon phase, and the strength of each day's major and minor feeding periods. Those are the factors a national calendar can actually know. Water temperature moves a fishing grade far more than the moon does, and it depends entirely on where you fish, so enter your location for a full grade that adds water temperature, weather, and barometric pressure.
September is when the year turns back in the angler favour. Cooling water pulls fish out of their summer depths, baitfish begin their autumn movement, and feeding windows widen back through the middle of the day. It is one of the most consistent months on the calendar, particularly in the north where the change arrives first.

Chinook Salmon, Snook spawn during September. Fish on beds are harder to tempt, so our grades apply a spawn-lockout penalty. Target pre-spawn and post-spawn species instead, or fish deeper staging areas nearby. Some species appear in both lists because spawning runs across the month, with northern waters lagging southern ones by several weeks.
Red Snapper, Snook, Wahoo are recovering from the spawn in September. Expect a short lull before they return to normal feeding, and favour slower presentations near spawning flats.
