That makes July a dependable choice if warmth matters, though hotter spells remain possible. Humidity averages 75%, which can make the heat feel sticky, particularly when you are walking around. Plan longer walks for the morning and leave room for a shaded break at midday. Loose, breathable clothing should be more useful than heavy layers.

Dry days and a sea that suits swimming
Rain is unlikely to disrupt your plans, with about 0 rainy days in a typical July.

This combination suits travellers who want to alternate time in the water with relaxed outdoor plans, rather than spend the hottest part of the day walking.
