The windward east and south coast gets heavy seasonal sargassum, but nearly every resort sits on the sheltered leeward west coast (Rodney Bay, Castries, Soufrière), which is rarely affected.
Current conditions
Our estimate: barely any sargassum this month — typically one of the more reliably clear beaches. Conditions still change day to day, so confirm with the resort.
An estimate modeled from live satellite readings (USF / NOAA AFAI) + 15-year seasonal history + beach orientation · refreshed August 8, 2026. Conditions change daily and many resorts rake their beach each morning — always confirm current conditions with the resort before you travel.
