Source: Meteorological data for Dominica is based on weather statistics gathered during 1992 to 2021 from the closest weather station: Douglas–Charles Airport (DOM), formerly known as Melville Hall Airport, located on the northeast coast of Dominica, around 3km (1.8mi) north of Marigot, and 46km (28mi) southwest of the capital, Roseau. Additional climate data is also sourced from Martinique Aimé Césaire International Airport (FDF), located 89km (55mi) southeast of Dominica on the island of Martinique, as well as from the United States National Oceanic and Atmospheric Administration (NOAA).
Advice on the best time to visit a particular destination is based on average local weather statistics, when the weather conditions are generally better than at other times of the year. We consider high and low temperatures, risk of rain (and thunderstorms, etc.), amount of sunshine and sea temperature. For general outdoor activities we favour clear, rainless days with a temperature range between 18°C (64°F) and 27°C (80°F); and for hot-weather activities we favour clear, rainless days with a temperature range between 24°C (75°F) and 32°C (89°F). Often, the best times to visit correspond to high season and therefore involve higher prices.
