WIND AND WEATHER IN THE GRENADINES

The weather on Union Island and in the Grenadines is different than the weather on the main island of St. Vincent.
The island are so small that most of the phone weather apps and website will not give you an accurate reading.
The Air temperature is 30°C all year long and the Water temperature is 28°C with very sunny weather most of the year.

Good weather all year

The high season from the beginning of November 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 October 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 November to the end of July and weaken in August until the beginning of November.

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

Low rainy Season – August to October

The Caribbean “raining season”, from July to the end of October 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 nice 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 but with very little wind.
