Hot days, with milder evenings
Pack mainly for summer rather than a British September: light, breathable clothes should suit most days. Temperatures reach 25°C on 79% of days, so warmth is a reasonable expectation, not just a lucky bonus. There is still a hotter edge, though: 17% of days reach 30°C, and humidity averages 70%, which can make the heat feel closer. Keep strenuous activity away from midday if you struggle with hot weather, and leave time for shade. Evenings are generally mild rather than chilly, but the average night low is not a guarantee. A light layer is sensible if you plan to sit outside late.
Good swimming weather, but allow for rain
The sea is a strong reason to choose September. At an average of 25°C, it is warm enough for swimming rather than just a quick dip; the year-to-year range of 24°C to 26°C also points to consistently warm water. Sunshine averages about 7.2 hours within 12.2 hours of daylight, leaving plenty of scope for outdoor plans without promising clear skies throughout. The catch is about 6 rainy days, so a completely dry holiday should not be assumed. Keep your swimming plans flexible and pack a light waterproof. If you need guaranteed sunshine, this is less reassuring; if you can work around some wet weather, the warmth still makes September appealing.
