Proper heat, with little relief at night

Average daytime highs of 30°C make October feel very different from London, where the average high is 14.6°C. This is weather for loose, breathable clothing and a slower pace during the hottest part of the day. Humidity averages 85%, so the temperature alone does not tell the whole comfort story: expect the air to feel sticky rather than crisp. Nights average around 25°C, which means evenings stay warm rather than offering much of a cool-down. Air-conditioned accommodation is a sensible priority if heat affects your sleep. Pack mainly light clothing, with anything waterproof chosen for ventilation as well as rain protection.

Rain is the main compromise

With about 25 rainy days, October is a poor fit if your main requirement is a reliably dry holiday. That does not mean every rainy day is a washout, but it does mean rain should be part of your plans rather than treated as an unlikely interruption. Keep outdoor arrangements flexible and have somewhere sheltered to spend time when conditions turn wet. Sunshine averages about 4.3 hours a day, so there is still scope for time in the sun, but not a basis for expecting clear skies all day. A light waterproof and footwear that can cope with getting wet are more useful than packing only for heat.

Warm water is a strong reason to go

The sea averages 29.4°C, making swimming a strong point of an October trip. If cold water usually puts you off getting in, temperature is unlikely to be the obstacle here. However, warm water does not establish that sea conditions are safe, so follow local advice before swimming. With about 11.6 hours of daylight, there is room to shift time outdoors around the weather rather than fixing everything in advance. Use brighter spells for swimming or relaxing outside, while keeping shade within reach. October works best for travellers who value warmth more than uninterrupted sunshine and will not feel their holiday is spoiled by regular rain.
