We are at the Carribean Sea so the climate is tropical. It is always hot and humid and there are often downpours.
It is really good to have an umbrella as it can protect you against the sun and the rain.
You really need a high factor sunscreen like 20 SPF or more.

When you are on the beach, it is pleasant. You can feel the gentle wind blowing. Far from the beach and you are sweating.
