How hot is it in Jamaica during August?

August is typically the hottest month in Jamaica. The temperature hits about 30℃ during the day, falling away to a balmy 25℃ 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 Jamaica during August?

On average, there will be 28 rainy days during the month, amounting to 130.2mm in total. That's a significant amount of rain. For comparison, the wettest months in the UK typically sees between 80mm and 100mm, depending on where you are. 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, August will see just 5 days that produce a storm.

How warm is the sea in Jamaica during August?

The water around Jamaica reaches a very pleasant 30℃ during August. This is very warm, and will feel bath-like. People who normally feel the cold will find this temperature perfectly acceptable. The hot air temperature will mean that you will feel comfortably warm when coming out of the water.
