When to Visit Dominica

January brings Dominica's version of cool: highs of 28°C (82°F) and comfortable nights around 21°C (71°F), with rainfall at around 160mm. It's solidly in the dry season. The trade winds are reliable. The island is close to its annual peak for visitors.

February is statistically the driest month, with rainfall dipping to around 107mm. Temperatures hold steady at highs of 28°C (82°F) and lows of 21°C (70°F). The combination of lower rainfall, refreshing breezes, and approaching carnival season makes this one of the year's more compelling arrival windows.

March sees a slight uptick in rainfall to around 135mm but remains firmly in the dry season, with highs of 28°C (83°F). The island is lush. The waterfalls are flowing well. Tourist activity stays strong through the Easter period.

April marks the early transition toward the wet season, with rainfall at around 122mm and temperatures nudging to highs of 29°C (84°F) and lows of 22°C (72°F). In practice the weather still feels largely dry. This remains a popular month, for diving, as water visibility tends to be excellent.

May is the start of the wetter period in earnest, with rainfall jumping to around 221mm, nearly double April's. Highs reach 29°C (85°F) and lows settle around 23°C (74°F). Afternoon showers become a daily expectation rather than an occasional surprise. Visitor numbers begin to ease.

June tips into hurricane season, though the statistical risk remains low this early. Rainfall sits at around 163mm and temperatures hold at highs of 30°C (86°F) and lows of 24°C (76°F). The island shifts into a quieter rhythm. The diving is often excellent in June, with warm water and decent visibility between rain events.

July brings the first of the wet months, with rainfall rising to around 180mm. Temperatures stay at 30°C (86°F) highs and 24°C (76°F) lows. The interior trails see regular downpours. The rivers and waterfalls run dramatically full. Visitors are sparse. Dominica feels more authentically local.

August is measurably wetter, with rainfall reaching around 244mm, and the hurricane risk becomes more concrete. Highs remain at 30°C (86°F) with lows around 24°C (75°F). This is when the island's rainforest earns its name. Waterfalls thunder. The vegetation is intensely saturated. Evening mists drift through the mountain valleys.

September is the statistical peak of both rainfall and hurricane activity, with around 297mm. Temperatures stay at highs of 30°C (86°F) and lows of 23°C (74°F). Travel insurance becomes non-negotiable. Still, visitors willing to accept the uncertainty find a Dominica that's almost entirely to themselves. Empty beaches. Quiet trails.

October is Dominica's wettest month, with rainfall often exceeding 333mm. Highs ease to 29°C (84°F) and lows to 23°C (73°F). The interior landscapes are at their most intensely green. Trail conditions require care and experienced guides. The sheer volume and force of the island's cascades, including Trafalgar Falls, is something only possible at this time of year.

November sees the heaviest rainfall of the calendar at around 373mm. The hurricane season winds down by the month's second half. Highs hold at 29°C (85°F) and lows at 22°C (73°F). Conditions improve toward the end of the month. This can be a good moment to catch Dominica transitioning back toward its drier, more accessible face.

December brings a marked improvement. Rainfall drops sharply to around 239mm and the holiday season draws visitors back. Highs settle at 28°C (83°F) and lows at 21°C (71°F). The trails are drying out. Accommodation fills for Christmas and New Year. Book early.
