Comfortable for walking, but pack for cold evenings

The daytime average is mild enough for walking with a jacket, but not a reason to pack only spring clothes. Warmer days can reach 17.4°C or more, while the coldest nights fall to 3.7°C or below. Bring layers you can remove when the afternoon feels warmer, plus something properly warm for evenings. Closed shoes and long trousers are a more useful starting point than sandals and shorts. March works best if you enjoy being out in cooler conditions; it is less convincing if your main aim is to sit outdoors in warmth from morning until late.

Leave room for rain, and treat the sea as cold

With about 11 rainy days, a waterproof jacket belongs in your bag, and outdoor plans need some flexibility. You may still find useful sunny spells: March averages about 5.6 hours of sunshine within 11.7 hours of daylight. That is time for getting outdoors, but it does not mean the day will stay bright or dry. Keep your plans movable rather than making every day depend on clear skies. The sea averages 13.9°C, which is cold rather than comfortably swimmable. If swimming is central to your holiday, March is a poor fit. For a break spent mostly on foot, with pauses indoors when rain arrives, the weather is easier to work with.
