Comfortable days, but pack for cool evenings

Plan for changeable levels of warmth rather than a suitcase of summer clothes. A T-shirt may feel comfortable in sunshine, but a jumper and a jacket give you options when it feels cooler. The warmest 10% of days reach 20.8°C or more, while the coldest 10% of nights fall to 6°C or below. That makes a warm evening layer more useful than extra swimwear. Days reaching 25°C account for just 1%, so midday heat is unlikely to dictate your plans. December works best for travellers happy to spend time outdoors without expecting to sit in beachwear throughout the day.

Use the daylight and leave room for rain

There are about 5.6 hours of sunshine within 9.6 hours of daylight, giving you a useful sunny window without the long days of summer. Keep outdoor plans flexible and make the most of brighter spells rather than leaving everything until late afternoon. Around 5 rainy days means a light waterproof is sensible, although rain need not be the focus of your packing. Sea swimming is the bigger compromise: the water is bracing, so treat a dip as optional rather than the main reason to travel. If warmer weather matters more than travelling in December, May, June and September are better choices overall.
