Climate of St. Vincent & the Grenadines

Located in the eastern Caribbean, the islands of the Grenadines and St. Vincent are known for their warm weather year-round, which, along with the azure waters of the surrounding ocean, draws visitors from all over the world. If you are planning a trip to St. Vincent or the Grenadines, remember that even the most comfortable climates can become uncomfortable from time to time. While sunny weather is typical, there are times that are wetter than others.

Temperature

Given the archipelago’s proximity to the equator, the temperature stays fairly constant throughout the year, and it rarely gets below 65 degrees F. The average high in January is 85 degrees and the average high in July is 86 degrees. It might be somewhat warmer in some interior areas of the larger islands, especially St. Vincent, which supports a tropical rain forest, but the ocean moderates the air temperatures to keep them relatively steady.

Rain

The dry season in St. Vincent and the Grenadines is the winter and early spring, especially from January through May. The wettest time is the summer, with July receiving the most precipitation. Rain falls for an average of 26 days in July in St. Vincent, but is mainly relegated to the northern third of the island. The Grenadines are generally drier. That leaves most of the day with good weather to enjoy beaches and other activities the islands offer.

Hurricanes

The hurricane season typically follows the rainy season, from June through November. However, unlike the much of the rest of the Caribbean, St. Vincent and the Grenadines are far enough to the south that they miss many of the storms. If they are affected, it is usually stray outer bands of the tropical systems that can produce some rain, but very little severe weather. The last time the Grenadines took a direct hit from a hurricane was 1955.

Winds

Although the winds might not factor into most vacation plans, they are very important considerations for some island activities. Most of the time, the winds around St. Vincent and the Grenadines move at approximately 15 knots, or about 17 mph, generally from an east or northeast direction, leading to optimum conditions for boating and fishing. Surfers might find even windier times more to their liking. Winds of 20 to 30 knots, or 23 to 34 mph, are common in January and February.

Humidity

In an area like St. Vincent and the Grenadines, where there is very little temperature variation from season to season, humidity becomes a key consideration. In the summer, it might feel much hotter than it is because of higher humidity levels. The winter tends to knock some of the humidity out of the air.
