Hurricane Season

The Atlantic hurricane season is the period in a year when hurricanes usually form in the Atlantic Ocean which can impact Dominica’s weather severely. Tropical cyclones in the North Atlantic are called hurricanes, tropical storms, or tropical depressions.

Dominica is especially susceptible to storms due to its central location in the archipelago. The Hurricane Season runs from June 1 to November 30 and the country prepares for possible storms by reinforcing homes and other buildings, stocking up on supplies (canned and other nonperishable food, water, fuel, medicine, etc.)

Best Times To Visit

Generally, the months December to May are considered the best times to visit Dominica. These are our driest months, which allows visitors to enjoy our hiking trails, waterfalls, rivers, and other natural attractions with less risk.
