You'll definitely get Caribbean weather when you're on St. Vincent but be forewarned it is a rainforest climate. It's so mountainous that clouds tend to gather over it - at least in early February. Be prepared for short but intense rainshowers every day or night. Having said that, the cloud coverage gives you a break from the intense sun. And as others report, you will get plenty of sunshine while you visit. The weather is also so changeable it can be a torrential downpour one minute and gorgeous the next. One other word to note - it gets extremely  windy in the winter- this may go on through the end of February. And by windy, this means big gusts if you're trying to lie on the beach! (Guess that's why it's a sailor's paradise).
