Warm enough for summer clothes, without reliable hot days

Expect warmth rather than scorching afternoons. Days reach 25°C on 39% of occasions, so September suits travellers who prefer comfortable outdoor weather over persistent heat. Midday is a sensible time to take shade if you feel warm, particularly with humidity averaging 70%, but intense heat is not the main concern. Average night lows are around 21°C, making light clothing a reasonable starting point for evenings. There is still a cooler tail: the coldest 10% of nights fall to about 19°C or below. Bring a light jumper or cardigan rather than assuming every evening will feel like an extension of the afternoon.

Good swimming weather, with room for rain

The sea is a strong reason to choose September: at 24.8°C on average, it falls comfortably into swimming territory. That makes time in the water a more dependable part of the appeal than very hot air temperatures. Sunshine averages about 7.4 hours within 12.2 hours of daylight, leaving useful time outdoors without promising clear skies throughout. Rain is the catch, so avoid building every day around uninterrupted sunshine. A light waterproof is a practical addition to swimwear and sun protection. Keep outdoor plans movable, and treat the monthly averages as a guide to the balance of the holiday, not a promise for your particular stay.
