Bite forecast in United States

Every morning the model rebuilds an hour-by-hour bite forecast for waters in all 50 states and the District of Columbia — the Great Lakes and the Mississippi system, the reservoirs of the South, high-country trout streams, and the Gulf and Pacific coasts. It reads air and water temperature, barometric pressure and the direction it is moving, wind, cloud cover and the season each species is in, then folds in the solunar windows around moonrise, moonset and the moon's transit. On tidal water the tide is layered on top: a redfish on a marsh flat keeps the tide's schedule, not the sun's.

The reports behind the forecast are unmistakably American. Largemouth bass account for close to half of everything logged, ahead of smallmouth bass and walleye; behind them come rainbow trout, black crappie, northern pike, striped bass, brown trout, channel catfish and king salmon. Minnesota, California, Michigan, New York, Texas and Florida send the most reports, and each state page carries its own catch map and month-by-month activity.

Readings come in US units by default — °F, miles, inHg — and the switch in the header moves them to metric. The bite score is computed per region rather than per lake, so two waters in the same state share it; what is genuinely local is the solunar window, computed from the page's own coordinates, and the tide on the coast. The forecast runs 15 days out, and past about a week treat it as a way to pick a weekend rather than a schedule.
