About water temperatures
Satellite-based sea-surface readings
Readings come from satellite and model sea-surface analysis (marine reanalysis via Open-Meteo). US waters peak in August and early September — the Gulf and South Florida run bath-warm in the 80s °F, Southern California in the upper 60s, and the Pacific Northwest stays cold year-round. Shallow, protected bays can run several degrees warmer than the open coast.
