Warm days, with a cooler edge after dark

Expect comfortable warmth rather than consistently fierce heat. Around 53% of days reach 25°C, while only 5% reach 30°C, so October suits you better if you enjoy being outdoors without wanting very hot afternoons. Midday can still feel hot, making shade, sunscreen and lighter clothing sensible. After sunset, the change is noticeable: the average low is 16°C, but the coldest nights can fall to around 13°C or below. A jumper or light jacket will make sitting outside more comfortable. Bring trousers as well as shorts, and avoid packing as though every evening will stay as warm as the afternoon.

Good swimming weather, but keep plans flexible

The sea is a strong reason to choose October: at an average of 24.3°C, it remains warm enough for swimming rather than just a quick dip. Sunshine averages about 8.1 hours within 11 hours of daylight, leaving useful time for outdoor plans, though that is not a promise of clear skies throughout your stay. The catch is rain, with about 5 rainy days during the month. Keep some plans flexible and pack a light waterproof rather than assuming sunshine every day. This is a good fit if swimming matters but you can accept occasional wet weather; less so if uninterrupted dry days are essential.
