When is the best time to visit Antigua?

For sun-seekers, the temperatures and sunshine amounts don’t vary too much throughout the year. The hottest months are during August and September, though these months also see some of the higher rainfall amounts - due to the hot and humid hurricane season. If you are looking for some winter sun, then Antigua makes for a perfect getaway, as average temperatures are still hot by UK standards, but with a refreshing breeze to lessen the intense heat, and generally lower rainfall amounts than the summer months. Hurricane season is usually from June to November, with the highest risk months being mid-August to mid-October.


Spring is a great time to visit this island paradise, with the tropical sunshine bringing temperatures between 28 and 30 Celsius on average. It is also the driest season in terms of both rainfall and humidity; so if you struggle with muggy, humid heat, then this is the best time of year to go. 


If you’re looking for the hottest season to go, then the summer months will provide plenty of scorching sunshine, as this is when temperatures are at their highest (30-31 Celsius on average). However, it can also get very humid at this time of year, with thunderstorms adding short bursts of intense rainfall from time to time, often at night. It is also part of the hurricane season, with a risk of strong winds and intense rain as tropical storms track nearby.


Autumn is also part of the hurricane season, with the average rainfall at its highest of the year in October (196mm). However, there are still a good 7 or 8 hours of sunshine on average, and with daytime highs between 29-31 Celsius, there is still plenty of clear blue Caribbean sky on offer in between the short-lived stormy weather.


With the UK at its coldest, winter is the perfect time to escape to the sunny shores of Antigua. Average temperatures are still hot, with highs reaching 28 Celsius on average, compared to the 6-10 Celsius in the UK. Winter is also the second driest season for this blissful sun-drenched holiday resort, with only 116mm on average.

Antigua tourist information

The island has a long tradition of sailing, thanks to the equatorial trade winds, which offer perfect conditions for the many world-renowned regattas which take place on Antigua. If you prefer a more relaxed approach to nautical excursions, there is plenty of opportunity to explore the coves and coral reefs at your leisure, or perhaps a sunset dinner cruise; viewing the many colours of the tranquil Caribbean sunset. Although the perfect white sandy beaches and jade sea are the main draw for most of the holidaymakers heading to this island paradise, there are also opportunities for thrill-seekers; zip-wiring through the tropical rainforest, or daring the suspended walkways through the lush green canopy.
