SOURCE LIMITATIONS & SAFETY NOTICE
Weather, rain and wind are Open-Meteo model guidance using nearby grid data. Wave and swell figures are Open-Meteo marine-model estimates from a regional offshore point, not live buoy or exact surf-zone observations. Tides are Tideschart St Lucia predictions; local mouth, current, sandbar and beach conditions can differ. Sun and moon data are Timeanddate astronomical calculations. Solunar periods are qualitative planning guidance; only today's Tideschart period was directly available at issue time and later-day windows are not presented as verified local observations.
Check current SAWS warnings, sea state, rips, shorebreak, surge, lightning, estuary-mouth status, access and local observations before fishing or launching. Follow current size, bag and seasonal regulations. This report is not an official warning.
