Sources: NOAA National Data Buoy Center (wave/wind/water temp) + NOAA Tides & Currents (tide predictions), live readings, plus NWS marine zone Today/Tonight forecast periods where available. Conditions calls are a plain rule-based read of these numbers, not per-break forecasts — see the site notes for why (buoys are far sparser than named breaks along this coast). NWS forecast text covers "Today"/"Tonight" trend periods, not hour-by-hour data.
