Comfortable afternoons, chilly evenings

Pack for spring rather than summer. The warmer days can reach around 21°C, making lighter clothing useful in the afternoon, but colder nights can drop to 5°C or below. Layers will serve you better than a suitcase built around shorts and swimwear: bring something light for daytime, a jumper and a jacket for after sunset. Midday is a sensible time for outdoor plans if you want the most warmth, rather than a period you need to avoid because of heat. March suits travellers who prefer mild conditions for walking, but it is a less convincing choice if sitting outside late in light clothing matters to you.

Useful sunshine, but keep beach plans modest

There is enough sunshine to make outdoor plans worthwhile, with about 6.3 hours a day on average, but do not expect clear skies throughout your stay. Around 6 rainy days across March make a waterproof layer and flexible plans sensible; rain is a possibility to work around, not a reason to rule the month out. Treat time by the sea as a chance to walk or sit out when conditions feel comfortable, rather than as a swimming holiday. The water remains cold even when the air feels pleasantly warm. If sea swimming is central to your trip, March is a poor fit regardless of how sunny an afternoon looks.
