Comfortable for walking, less reliable for sunbathing

The daytime average is mild enough for walking without having to organise everything around avoiding midday heat. There can be warmer spells: the warmest 10% of days reach 23°C or more, but only 3% reach 25°C. Treat T-shirt weather as a bonus rather than the basis of your packing. Bring trousers, light layers and a jacket for evenings, when the average low is 12.4°C. The coldest 10% of nights fall to 7.9°C or below, so a warm layer is more useful than a suitcase packed mainly for summer. This is a better fit for travellers who prefer mild afternoons to hot ones.

The sea is bracing rather than warm

At 18.5°C, the average sea temperature makes swimming a bracing prospect rather than an easy way to spend a long afternoon. Across years, October's sea temperature ranges from 17°C to 20°C, so even the warmer end is below the 22°C benchmark for comfortable swimming. If you already enjoy cooler water, a dip may still appeal; if you usually need warm seas, do not make swimming the main reason to go. Pack swimwear if you want the option, but give dry clothes and a warm layer equal priority. The catch is that mild air does not mean a warm sea.

Keep outdoor plans flexible

October brings about 7 rainy days, so rain is something to plan around without assuming it will dominate the holiday. A light waterproof and shoes you are comfortable wearing in wet weather are sensible additions. Sunshine averages about 4.7 hours within 10.8 hours of daylight: there is time to be outdoors, but daylight should not be confused with uninterrupted sun. Keep your plans flexible enough to use brighter spells for longer walks or time by the sea. If your idea of a successful break depends on clear skies every day, October is not a dependable choice; it suits a more flexible approach.
