Hot days without much evening relief

The heat is consistent rather than regularly extreme: days reach 25°C throughout October, while reaching 30°C is unusual. That makes light summer clothing the sensible starting point, but the 81% humidity is an important part of the picture. You may find walking around less comfortable than the temperature alone suggests, especially at midday. Keep active plans flexible, take shade breaks and choose loose, breathable clothes. Evenings offer little cooling, so do not expect the temperature drop you would get at home. If you struggle to sleep in warm conditions, prioritise accommodation with air conditioning rather than relying on cooler night air.

Plan around rain, not a washout assumption

October is wet, with about 22 days recording measurable rain, so a rain-free holiday is not a sensible expectation. That does not mean those days are wet from morning to night, but the figures do not tell you when rain will arrive or how long it will last. Sunshine averages about 5 hours within 11.6 hours of daylight: there is scope for time in the sun, but plenty of daylight without it too. Pack a lightweight waterproof and keep something dry for later. This month suits travellers who can rearrange outdoor time more than those whose enjoyment depends on clear skies every day.

Warm sea is the strongest reason to go

At 28.8°C, the sea is firmly in comfortable swimming territory. Its October range of 28°C to 29°C also makes warm water a dependable part of the appeal, although sea temperature alone cannot tell you about swimming conditions on any particular day. If your main aim is to spend time in the water and relax between swims, the balance of heat and rain may work for you. Just remember that a warm sea will not provide a sharply cool contrast to the air. Keep sun protection handy even when skies are mixed, and let the day's weather guide how long you stay outdoors.
