Today's AI read

Active-water pattern for Largemouth bass / Smallmouth bass

58 confidence

Active temps make wind edges, shallow cover, and feeding windows more important. Wind is not the main constraint, so timing and presentation can drive the plan. With a weak solunar score, favor stable weather windows.
