Warm enough for summer clothes, with a layer for evenings

Pack mainly light clothing: 62% of September days reach 25°C, so there is a good chance of weather warm enough for sitting outside or spending time by the water. Midday can still feel hot, particularly with humidity at 72%, so shade and a break from the sun are sensible. Days reaching 30°C are relatively uncommon, at 5%, making September a reasonable fit if you like warmth but would rather avoid very hot conditions. Evenings are milder than the daytime figures suggest. The average low is 18°C, but cooler nights can dip to around 15°C or below, so bring a jumper or light jacket rather than packing only beachwear.

Good swimming weather, but leave room for rain

The sea is a strong reason to choose September. At an average of 24°C, it is warm enough for swimming rather than just a quick, bracing dip; the year-to-year range of 23°C to 25°C supports that judgement. Rain is the main compromise, with about 9 rainy days during the month. That does not tell you how long each wet spell will last, so neither a washout nor uninterrupted beach weather is a sensible expectation. Take a light waterproof and keep some plans that do not depend on being outdoors. September suits travellers who want a warm sea and can adjust their days around the weather; it is less convincing if dry skies are your main priority.
