Temperatures in Antigua are warm year-round and are generally between 25–30°C, dropping a few degrees in winter (Dec–May) and heating up again in June, July and August. June to November (the hurricane season) sees the heaviest rainfall, with occasional tropical storms.
The peak visitor season is between December and February. Try March, April and May for family holidays, when there are fewer visitors (and lower prices) but the weather is still gorgeous.
Antigua’s annual Carnival occurs in July and August so don’t miss this if you do decide to travel at this time.
