How warm is it in Saint Lucia during May?
The temperature is extremely stable in May with average highs of 29℃ and lows just 3℃ lower at 26℃. 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.

On average, there will be 2 rainy days during the month, amounting to 71.9mm in total. That's broadly comparable with the amount of rain we see in England during the summer months, and would be considered dry. Due to the high temperature and humidity, you might expect lots of thunderstorms, however they're actually fairly infrequent at this time of year. On average, May will see just 1 days that produce a storm.
Is it windy in Saint Lucia during May?
Expect moderate breeze becoming stronger at times during May, with occasional gusts up to 19mph. The high humidity and warm temperature will make the breeze feel warm, so any cooling effect will be limted.
How warm is the sea in Saint Lucia during May?
