Mild afternoons, but pack for cool evenings

An average high of 14.8°C makes January comfortable for walking if you dress for cool weather rather than summer. The warmer days reach 17.4°C or more, so a sunny afternoon can be pleasant for sitting outside, but warmth is not guaranteed. Night-time temperatures average 10°C, with the coldest nights dropping to 7.2°C or below. Bring trousers, a jumper and a jacket you can add as the afternoon cools. Keep outdoor plans towards the middle of the day to make the most of the warmth. This is a reasonable choice for travellers who dislike heat, but a poor match if you want to spend the day in swimwear.

Plan around daylight, showers and a cold sea

January offers about 5.4 hours of sunshine within 9.6 hours of daylight, so there is scope for time outdoors without expecting clear skies all day. About 6 rainy days means a waterproof jacket is sensible, and plans that can move around are more useful than a fixed outdoor schedule. Use brighter spells for walks and leave room for breaks indoors when rain arrives. The sea is the bigger limitation for a beach-focused trip: at 14.8°C, it is cold rather than merely bracing. Even its year-to-year range of 14°C to 16°C stays firmly cold. Treat time by the water as a chance to walk or sit in suitable clothing, not as a promise of comfortable swimming.
