Best time to snorkel in St. Lucia

The seasonal pattern for St. Lucia — what each stretch of the year tends to bring, and what to plan around. Guidance, not a forecast.

Seasonal pattern, not a forecast — conditions vary; verify tides, weather and visibility locally before you go.

The seasonal pattern

The drier months, roughly December to May, tend to bring the calmest seas and the clearest water on St. Lucia's sheltered west coast. The leeward bays are protected from Atlantic swell, but a long-period swell or a spell of wind can still stir them and cut visibility. From roughly June to November the island is wetter and sits inside the Atlantic hurricane season, so keep plans flexible — boat days get cancelled for weather here like anywhere in the region. Water stays warm year-round, and mornings are usually calmest before the trade wind builds through the afternoon.
