Weather in Union Island

Union Island is the southernmost inhabited point of St. Vincent and the Grenadines, a dramatic spike of green peaks rising from the Caribbean Sea that doubles as the gateway to the Tobago Cays. Clifton, its small main town, has a yachtie, easygoing energy thanks to its role as a customs checkpoint for boats heading further into the Grenadines, with colourful sloops and a lively Saturday market. Hiking up Mount Taboi rewards with views across to Carriacou and the Tobago Cays marine park, while the surrounding reefs make it one of the best bases for day-sailing trips.

Traveler reviews

★★★★★

Day-sailed out to the Tobago Cays from Union Island and it was one of the most beautiful spots I've ever swum — turtles everywhere and crystal-clear water.

★★★★☆

Clifton has a really nice, unpretentious yachtie vibe. Great spot to refuel before island-hopping further into the Grenadines.

Hiked up Mount Taboi for sunrise and the views over the surrounding islands were spectacular. Chatham Bay afterwards was almost completely deserted.
