Hatch outlook

Hopper & ant season (windward banks)Active window

Typical here: Jul 1 – Sep 15 · hoppers peak July–August; winged-ant falls show up on warm humid afternoons — a wind event, not a hatch

adultwarm, breezy afternoons, roughly 1–5pm — slap the imitation down hard — the splat is the trigger — then wait; count to three after the rise before setting

Work the windward bank on breezy summer afternoons — that's where the food is. Casting-bubble-and-hopper is the direct translation; otherwise run small topwaters and inline spinners tight along the grass edges and blowdown banks in the afternoon warmth.

The event happens over windward grassy banks, overhanging brush and blowdowns — wherever the breeze dumps the bugs
