Antigua : climate and when to go to Saint johns
Tropical, humid and insular climate. This tropical climate divides the year into two seasons: a dry period from December to April, with a lot of sunshine and supportable heat, and a rainy season from May to November, as hot but with a higher humidity, in the form of intense but very short showers occurring in the evening. It is also during this period that hurricanes pass over Antigua and Barbuda, the sister island north of Antigua. The best time to visit the archipelago is the dry season.

Weather uncertainties 2025 to go to Saint Johns ?
When traveling in the tropics as a seaside, rain is not welcome. If you see this indicator, with possible storms, that does not mean that it will rain all day long. When we observe the local rainfall, it is either really zero or very weak. Meteorologists prefer to be pessimistic. So observe below, the skies photographed during a week announced stormy in Asia. It did not rain once. I invite you to integrate this parameter before going to Saint Johns for a good trip to the sun!
