Mild afternoons, cool evenings and a cold sea

The daytime average of 15.7°C makes walking more appealing than sitting outside for long stretches without a jacket. Warmer days can reach 19.1°C or more, but do not pack as though that warmth is guaranteed. Evenings need another layer: the average night low is 9.7°C, while colder nights can fall to 5.6°C or below. Bring a jumper and a jacket that can handle rain, with comfortable waterproof footwear rather than relying on summer shoes. The sea averages 15.5°C, firmly in the cold category. For most travellers, that makes November a month for time beside the water rather than relaxed swimming.

Plan around rain and limited sunshine

Rain is the bigger compromise than temperature. With about 13 rainy days, a waterproof outer layer should be part of your everyday kit, not something left in your luggage. That figure does not mean every wet day is a washout, but it does make an entirely outdoor itinerary a gamble. Sunshine averages about 3.8 hours within 9.6 hours of daylight, so keep your walking plans flexible and use brighter spells when they arrive. Put weather-dependent activities in daylight hours and leave room for indoor breaks. November works best if you enjoy exploring in cooler conditions and will not feel the trip has failed when rain changes the plan.
