Antigua's weather - an overview

Antigua is the largest of the Leeward Islands and its inhabitants are heavily into tourism and cricket. Its 'sister' island, Barbuda, is a complete contrast: very exclusive with just two luxury hotels and a frigate colony.

Torrential rain and the occasional hurricane can afflict these islands between July and November but, outside the rainy season, the islands are drier than many parts of the Caribbean.
