August Weather in Antigua and Barbuda
Is August Right for You?
Advantages
- Peak trade wind season - constant 15-20 knot breezes make 30°C (86°F) feel comfortable and create perfect sailing conditions
- Lowest accommodation prices of the year - hotel rates drop 40-60% compared to winter peak season, with luxury resorts offering August-specific packages
- Carnival season culminates in the first week of August with the largest cultural celebration of the year featuring steel pan competitions, calypso shows, and street parades

Considerations
- Hurricane season is most active - while Antigua averages only one direct hit every 7 years, weather tracking and potential evacuation procedures should be understood
- Afternoon thunderstorms occur 12-14 days per month, typically 2-4 PM, producing intense rainfall of 25-50mm (1-2 inches) in 30-45 minutes
- High humidity at 78% makes morning activities essential - by noon, the combination of heat and moisture becomes oppressive for extended outdoor activities
