Beach weather is common through the month, with the cooler days ideal for more active pursuits and outdoor sightseeing. If it will be hot throughout your stay, you may prefer to do your most active sightseeing in the mornings, saving air-conditioned attractions such as museums for the afternoon.

High-factor sun screen remains a necessity for all complexions. An umbrella is strongly advised, as is insect repellent if you will be spending any time in nature.
