Expect summer heat, not gentle autumn warmth

Pack mainly for hot weather: light, breathable clothes, a hat and sun protection will be more useful than autumn layers. Temperatures reach 30°C on 54% of days, so September is not a reliable choice if you find that level of heat uncomfortable. The warmest 10% of days reach 34.5°C or more, making shade and breaks particularly useful around midday. Plan more active time for mornings and leave room for a slower afternoon. Evenings are milder, with average lows of 19.6°C, but a light layer is sensible: the coldest 10% of nights fall to 16.7°C or below. You can travel light without assuming every evening will feel warm.

Warm swimming water with little rain

The sea is a strong reason to choose September. At an average of 27.7°C, it is warm enough for comfortable swimming rather than a quick, bracing dip. The year-to-year range of 27°C to 29°C also points to consistently warm water. Rain is less likely to dictate your plans, with about 2 rainy days during the month, though dry weather is not guaranteed for your particular stay. Keep some flexibility rather than treating every day as certain swimming weather. For a holiday built around the sea and relaxed outdoor time, the balance is favourable; the main compromise is managing the heat, not waiting for the water to warm up.
