Expect serious daytime heat and warm evenings

The main catch is how much the heat shapes your day. With average highs of 36.7°C and the hottest days reaching 39.5°C or more, midday is better kept for shade or an air-conditioned break than sustained outdoor activity. Put any walking earlier in the day, carry water and choose loose, lightweight clothing. Humidity averages 36%, but relatively dry air does not make this mild weather. Nights average 24.9°C, so evenings are warm rather than reliably cool; breathable clothes should be more useful than heavy layers. If you struggle to sleep in warmth, prioritise air conditioning when choosing your accommodation.

Warm sea, plenty of sun and little rain concern

The sea is a strong reason to choose September: at an average 27.6°C, it is comfortably warm for swimming rather than something you need to brace yourself for. It may not feel particularly cooling after time in the sun, though. Sunshine averages about 11.9 hours a day, making shade, sunscreen and a hat everyday essentials rather than backup items. Rain is unlikely to disrupt your plans, so wet-weather clothing need not dominate your packing. Build your days around swimming and sheltered breaks, but do not treat time in the water as a substitute for sun protection. This weather rewards a relaxed pace.
