Hot days, with little cooling after dark

Pack for sustained warmth rather than a holiday that needs layers morning and evening. Light, loose clothing is the practical choice, and breathable nightwear makes sense with average lows around 22°C. Humidity is 74%, so allow for a sticky feel when walking or sitting away from shade. Days reaching 30°C are a minority, but the midday warmth still calls for breaks, drinking water and sun protection. There is about 8.4 hours of sunshine a day, leaving plenty of scope to spend time outdoors without making the hottest part of the day your main activity window. If you dislike warm nights, that is the main compromise here.

Good swimming weather, with rain unlikely to interrupt

The sea is warm enough for swimming, so May makes sense if time in the water is central to your holiday. Its average temperature of 24.6°C should feel comfortable for many swimmers, though personal tolerance varies. Rain is unlikely to dictate your plans: May is very dry, making wet-weather clothing a lower packing priority than sun protection. That is not a promise of completely rain-free weather, but it does favour flexible outdoor days without much need to plan around showers. Make shade part of the routine between swims, and remember that warm water does not tell you anything about waves or currents: check local conditions before entering.
