Climate Guide for May

The Southeast Trades set-in, winds pick-up, however the sea is not yet forbidding. You should be able to enjoy long sunny days – in fact this is the sunniest part of the year.
Precipitation further decreases as we enter the drier period of the year and as indicated in table below, May normally experience only few rain days.

May offers a slight relief from the oppressive heat as a gentle southeast breeze brings slightly cooler air from the south. We’re actually approaching the cool season in the south.
