Warm enough for swimming, humid enough to need breaks

This is still hot-weather territory: 97% of days reach 25°C, although only 5% reach 30°C. The bigger consideration is humidity at 77%, which can make walking around feel more tiring than the temperature alone suggests. Choose light, breathable clothing and leave room for shade or indoor breaks around midday. Evenings offer limited cooling, so don't plan on needing autumn layers outdoors. The sea is comfortably warm for swimming, making October a reasonable fit if time in the water matters more to you than dry weather throughout your stay. It is less suited to travellers who prefer crisp evenings or low humidity.

Allow for rain rather than planning around clear skies

There are about 15 rainy days in October, so wet weather is a routine consideration rather than a remote possibility. That does not mean those days are wet throughout, but it does mean a fixed outdoor schedule could be frustrating. Keep swimming and other outdoor plans movable, and pack a light waterproof that will not feel too heavy in the heat. Sunshine averages about 5.2 hours within 11.4 hours of daylight, leaving plenty of daylight without a promise of clear skies. October suits someone happy to work around the weather; if rain would spoil the main purpose of your holiday, it is a compromise rather than an obvious choice.
