High / low are average daily temperatures (°C). “Feels” reflects how hot or cold it feels, allowing for humidity.

Roseau & Southwest Coast (Roseau, Mero, Scotts Head, Champagne Reef)

June marks the start of the official rainy and hurricane season and Roseau will feel more languid with heavy tropical downpours interspersed with bright breaks. Ocean conditions can turn choppy within hours, making small-boat excursions to Champagne Reef or whale watches more weather-dependent; always check with operators. Pack a sturdy rain jacket and plan land activities (museums, food tours) as backups for sudden showers.

North Coast & Cabrits Peninsula (Portsmouth, Cabrits National Park, Calibishie)

June signals the start of the rainy season and the northerly exposures get regular, sometimes persistent rain driven by the northeast trade winds. Prince Rupert Bay still offers sheltered anchorages but rough weather can make open-water crossings to nearby islets uncomfortable. Always check ferry schedules and sea forecasts, and carry waterproof luggage because equipment and electronics risk getting wet during sudden squalls.

East / Atlantic Coast (Castle Bruce, La Plaine, Marigot, Grand Fond)

June ushers in regular, sometimes heavy rain and the Atlantic coast feels windier and wetter than the leeward side, with long periods of showers and more frequent gale-force gusts during storms. Ferries and small-boat operations along the east coast are more likely to be suspended, and hiking remote coastal trails becomes hazardous after heavy rain. Pack waterproof footwear, a durable rain jacket and plan to shift to shorter, safer excursions.

Central Highlands & Morne Trois Pitons National Park (Boiling Lake, Emerald Pool, Trafalgar Falls, Waitukubuli Trail high sections)

June brings steady, frequent rain at altitude and sometimes thick cloud that reduces long-range views; the central highlands are substantially wetter than the lowlands, and days can be cool and damp. Trekking windows shrink and guides sometimes postpone long hikes after heavy storms due to slippy sections and swollen rivers. For those prepared with the right gear, the rain gives the park an otherworldly, emerald quality and powerful waterfalls.

Southern Peninsula & Soufrière Area (Soufrière, Scotts Head peninsula, Grand Bay)

June moves the area solidly into the rainy/hurricane season so rainfall is frequent and afternoons can be showery; the peninsula remains scenically lush but outdoor plans should allow for sudden weather changes. Whale-watching and diving are still possible on calm mornings, but charter companies may cancel if swell or storms are forecast. Bring waterproof storage for electronics and be alert to official weather notices during the hurricane window.
