High / low are average daily temperatures (°C). “Feels” reflects how hot or cold it feels, allowing for humidity.
Antigua - St. John’s, English Harbour & Southwest Coast
The combination of high humidity and warm nights makes sleep steamy without air conditioning in smaller guesthouses, though many hotels use fans or AC. Rain episodes are heavier and less predictable - keep flexible arrangements for island tours or charters. This is still a lively time for local festivals, but travelers should follow forecasts for tropical developments during the wider hurricane season.
Antigua - East Coast & North Shore (Half Moon Bay, Devil’s Bridge, Long Bay)
Winds often gust stronger now and sudden squalls can cut visibility; however, sunsets seen from the north shore compensate with broad, clear horizons between showers. Snorkel operators adjust schedules to the mornings; timing trips with slack tides improves visibility. If you’re vulnerable to motion sickness, avoid crossing to exposed anchorages during windy afternoons.
Barbuda - Codrington, Frigatebird Sanctuary & Pink Sand Beaches
The air becomes muggy with long, warm nights that make open-air dining pleasant, and the island feels quieter since some visitors avoid this wetter stretch. Wildlife and birdlife are conspicuous and active after evening rains, making guided nocturnal walks interesting. Ferry crossings may be affected by higher seas so keep flexible travel plans and allow extra time on return trips to Antigua.
Marine & Sailing Conditions (Inter-island passages, reefs and hurricane season)
Late summer is the climatological peak of cyclone risk; many charter companies reduce operations during active advisories and ferries may reroute or cancel. When it’s calm, water is its warmest and reef life is spectacular, but sailors and divers need contingency plans for sudden weather changes. Keep copies of emergency contacts and follow local radio for harbour advisories.
