Traveller notes on Roseau in April
Forum posters consistently describe Dominica, 'the nature island,' as the most rainforested of the Eastern Caribbean islands - genuinely rainy somewhere on the island most days, which posters point to as exactly why it stays so lush and green with so many rivers. Posters are equally consistent that showers here tend to be brief, usually followed quickly by sunshine again, and one visitor's multi-week April-May stay in Roseau itself saw no rain at all, even as areas just a few miles inland got frequent heavy downpours. Posters generally name the December-through-April stretch as the main dry season with the calmest seas, and specifically recommend April for hiking, noting that conditions only get hotter and wetter as hurricane season approaches in the summer months.
Other months in Roseau
Dominica's forum is upfront that October sits in peak hurricane season, so the odds of a tropical wave or storm affecting a trip are real, though a direct hit remains the exception rather than the rule. As a lush rainforest island, it's genuinely going to rain somewhere on Dominica most days, but posters describe showers as typically brief and scattered, heavier up in the mountains than down in Roseau itself, with a lot of the rain falling overnight. October through December is actually recommended by some specifically for the World Creole Festival, drawing visitors despite the storm risk.
