The tropical island of Antigua sits on the boundary between the Atlantic and Caribbean and is a favourite holiday destination for British tourists. May is the first month of the rainy season, so tropical downpours will be more prevalent. Don't let that put you off - temperatures are still warm and hot sunny weather is found in between downpours. We've looked at the most up-to-date weather data for Antigua, covering the last 12 years up to 2024, plus we've asked our team of travel bloggers for their first-hand experiences in order to answer the most frequently asked questions about Antigua weather in May.
