Mild afternoons, but pack for cooler spells

An average daytime high of 18.4°C makes November comfortable for being outdoors without the heat dominating your day. The warmer days reach 21.2°C or more, so lighter clothing can be useful, but this is not a dependable hot-weather month. Nights average 15.7°C, with the colder ones dropping to 12.2°C or below. Pack a jumper and long trousers for evenings rather than relying on summer clothes throughout. If your priority is avoiding strong heat, November is a reasonable fit. If you want warm evenings in light clothing, the temperatures make it a less convincing choice.

Rain is the main compromise

The bigger limitation is wet weather rather than cold. With about 12 rainy days, you should expect rain to affect some of your plans, though that does not mean every wet day is a complete washout. A waterproof jacket is more useful than packing only for sunshine, and it helps to keep outdoor plans movable. There are about 4.8 hours of sunshine within 9.9 hours of daylight, so sunny spells are part of the picture, but not something to build every day around. Plan your outdoor time for daylight hours and treat a clear forecast as an opportunity, not a promise for the whole stay.

Swimming is possible, but the sea is bracing

The sea averages 20.3°C, which puts it in the bracing category rather than comfortably warm swimming weather. Its November range of 19°C to 21°C also suggests you should not count on an unusually warm sea changing the character of the trip. A swim may appeal if you tolerate cooler water, but it is better treated as an option than the main reason to book. Bring swimwear if that sounds like you, alongside something warm to put on afterwards. For travellers who want lingering swims and dependable warmth on shore, November's combination of mild air, wet weather and cooler water is a compromise.
