Antigua weather at a glance
There is no weather station in English Harbour. The numbers on this page were measured at V. C. Bird International Airport and are a guide for the island, not a reading for the harbour. They are long-term averages for 1981 to 2010 from the national weather service, Antigua Met: average monthly highs and lows of the daily temperature and average monthly rainfall.
They are not a forecast for 2026 or 2027 and not record values. The averages also say nothing about a single day. A dry month can still have a wet afternoon, so check the current forecast before a boat trip or a hike.

February (44.9 mm), March (46.0 mm) and January (56.6 mm) are the three driest months in the table. Daily highs stay between 28.3 and 28.8 °C, among the lowest of the year. Dry on average does not mean dry every day.

Hurricane season in Antigua
1 June to 30 November.
Antigua Met lists the hurricane season as 1 June to 30 November. Antigua is not hurricane-free, and the sheltered setting of the old naval harbour does not make the area storm-proof. Storms can change course within days, so read the cancellation terms of a hotel, a car hire or a boat trip before you pay.
Check the forecast of the Antigua Met Service shortly before every sea trip and again on the morning of the trip. The same season applies across the Caribbean. For a neighbouring island, see the St. Thomas weather guide.
Boat and snorkel trips
Weather can cancel a boat trip. Operators set their own rules, so compare what each one offers if a trip is called off.
Snorkeling guide →Hikes
One local hiking operator runs the Pillars of Hercules section only if the weather permits. The Middle Ground trail has steeper parts and ropes in places. Bring sturdy shoes, sun and insect protection and a hat. Flip-flops are not suitable, according to a nature reserve operator.
Hiking guide →Beaches
Currents can be strong around Antigua and not every beach has lifeguards or warning flags. Calm weather does not remove that.
