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.

Spring Fishing Tips
Spring brings warming waters and pre-spawn activity. Fish move shallow to feed heavily. Focus on warming flats, creek channels, and areas with early vegetation. Morning bite improves as water temperatures rise.
Best Fishing Days in May 2027
The top-rated fishing days in May 2027 are May 5, May 21, May 6, May 4, May 18, 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.
May is the peak of the spawn for most warmwater species, which is both the opportunity and the complication. Fish are shallow and visible, but fish on beds are focused on defending them rather than feeding, so the best action often comes from those that have finished and from the pre-spawn stragglers in slightly deeper water. Northern waters run several weeks behind southern ones, so the same date can mean different things.
