Comfortable for walking, but pack for cool evenings

Think light layers rather than a suitcase packed only for summer. The average daytime high of 16.5°C is mild enough for walking without planning everything around avoiding midday heat. Warmer days reach 19.8°C or more, but days reaching 25°C account for just 1%, so dependable sunbathing weather is not a sensible expectation. Nights average 11.2°C, with the coldest dropping to 8.4°C or lower. Bring a jumper, long trousers and a jacket for evenings, and keep a lighter layer handy during the day. April works best if you value comfortable outdoor activity more than hot weather and do not mind adjusting your clothing as temperatures change.

Useful daylight, some rain and a cold sea

There is plenty of daylight for flexible plans: April averages 13.1 hours of daylight and about 6.9 hours of sunshine daily. That gives you scope to make use of brighter spells, but it does not promise clear skies throughout your stay. About 7 days have rain, so bring a waterproof and avoid making every day depend on dry weather. The sea is the bigger limitation for a beach-focused trip. At an average of 14.6°C, it is cold rather than merely bracing, and the year-to-year range of 14°C to 15°C offers little reassurance for comfortable swimming. Plan seaside time around walking or sitting out when conditions feel pleasant, not long swims.
