Best Time to Dive Dominica
The best time to dive Dominica for most visitors is the drier season from about December to May, when seas are calmest and whale sightings peak. But the water is warm all year, and the quieter months have their own advantages.
The short answer
Diving Dominica through the year
Dominica is a tropical island with two main seasons. From roughly December to May the weather is drier, the trade winds are steady and the leeward (west) coast, where the diving is, is usually calm. From June to November the weather is hotter and wetter, and this is also the Atlantic hurricane season. Because almost every dive site is on the sheltered west coast, you can dive in every month of the year. Dive centres run trips in every season, although a few close for some weeks in the autumn.
So the best time to dive Dominica depends on what matters most to you: the calmest seas and the best odds of seeing whales, or warmer water, lower prices and empty dive boats.
Season by season
Dominica dive seasons compared
December to May
Dry season and high season. Less rain, calm seas on the west coast and the best visibility on most days. Sperm whale sightings are most frequent. Flights and rooms book up, especially around Christmas, Carnival and Easter.
June to August
Early wet season. Warmer water and more showers, usually short. Early hurricane season, though the most active weeks normally come later. Fewer visitors and quieter dive boats.
September to November
Peak hurricane season. The warmest water of the year but the highest risk of storms. Some dive operators and hotels close for part of this period. Travel insurance is essential.
Conditions
Water temperature, visibility and wetsuits
Water temperature stays warm all year, from around 26 °C (79 °F) in the cooler months to around 29 °C (84 °F) in late summer and autumn. A 3 mm wetsuit is enough for most divers; a shorty works for some in summer, and people who feel the cold may want a hood or vest for several dives a day in winter.
Visibility is often excellent on the walls and pinnacles, because they drop into deep, clear ocean water. It can drop near river mouths after heavy rain, when runoff from the mountains clouds the shallows. If it has rained hard, your guide may choose sites further from the rivers.
Sea conditions on the leeward coast are usually calm, with the island blocking the Atlantic swell. Northern swells in winter and passing storms in summer can make some sites rough for a day or two. Currents are strongest around points such as Scotts Head.
Hurricane season: the Atlantic hurricane season runs from 1 June to 30 November. Dominica was hit hard by Hurricane Maria in 2017 and has rebuilt since. If you travel in these months, buy travel insurance that covers storms, book flexible fares, and keep an eye on forecasts.
Whales and events
Timing your trip around whales and festivals
Sperm whales live off Dominica all year, but sightings are most frequent from about November to April. If seeing whales is a priority, travel in those months and book a trip early in your stay so you have time to try again. Read the Dominica sperm whales guide for how encounters work.
Dominica's Carnival (Mas Domnik) takes place in the days before Lent, usually in February or March. Independence celebrations are held in early November. These are lively times to visit, but rooms and flights fill up.

Our pick
So when should you go?
- First dive trip to Dominica: February to May, for calm seas, good weather and the best chance of whales. Book flights and rooms early for these months.
- Underwater photographers: the drier months, when there is less rain runoff and the best visibility for wide-angle; macro diving is good all year. See the macro diving guide.
- Budget and quiet boats: June to August, before the peak of the hurricane season.
- Avoid if you can: September and October, unless you are flexible and insured.
Once you have chosen your dates, the Dominica dive trip planning guide covers flights, where to stay and what to sort out before you go, and the dive sites guide helps you plan your dives.
