How warm is it in the Caribbean during March?

The temperature reaches around 29℃ during the daytime in March, falling away to 21℃ at night. Of course, the high humidity will make it feel even hotter. The UV index will be high at this time of year, so protection against skin and eye damage is needed. Try to limit exposure between 10am and 4pm. Apply broad spectrum SPF 30+ sunscreen every few hours, even if it's cloudy, or more frequently after sweating or swimming, and wear UV-blocking sunglasses too, and bear in mind that bright surfaces, such as sand and water increase UV exposure.

Does it rain in the Caribbean during March?

March is typically the driest month in the Caribbean. On average, there will be 2 rainy days during the month, amounting to 27.3mm in total. That's much drier than we see in England during August, and therefore not something to be concerned about. You're not likely to see a thunderstorm during your trip.

Is it windy in the Caribbean during March?

You're unlikely to experience any strong winds. Expect a gentle breeze that increases to moderate at times during March. The high humidity and warm temperature will make the breeze feel warm, so any cooling effect will be limted.
