The weather

Good weather all year

The high season from the beginning of December until the end of July offers an amazing sunny weather with very little to no rain and great trade winds to cool you down from the hot days.

From August to the end of November the weather can be amazing with little showers in the morning but clearing out for the afternoon.

Excellent Wind and Temperature

The Trade Winds blow consistently from December to the end of June and weaken in August until the beginning of December.

The Air temperature is 30°C all year long and the Water temperature is 28°C so no need to bring a wetsuit.

Low Hurricane Season – August to November

The Caribbean “hurricane season”, from July to the end of November is very weak and almost non existent in the Grenadines and Union island where most of the Hurricanes take a more northerly path.

The Caribbean hurricane season offers some of the best weather conditions to visit the Grenadines with very little rain ( occasional morning shower clearing up the afternoon) and very blue skies with very few tourists.
