Warm afternoons, but pack for cooler nights

Light clothing should work well during the day, but bring a jumper or light jacket for evenings rather than assuming it will stay warm after dark. The coldest 10% of nights fall to around 12°C or lower, so an extra layer could make a real difference. At the other end, the warmest 10% of days reach around 29°C or more: keep your plans flexible enough to take a break from the midday heat. Days reaching 30°C are uncommon, at 3%, making March a sensible choice if you enjoy warmth but find hotter conditions tiring. Think comfortable daytime warmth, not guaranteed heat throughout your stay.

Swimming weather, with room for rain

The sea averages around 24°C, warm enough for swimming, although how comfortable it feels will depend on your own tolerance. That makes March suitable for a holiday mixing time in the water with other outdoor plans. Rain is still part of the picture, with about 7 rainy days during the month, so pack a light waterproof and leave some flexibility in your schedule. That figure does not mean those days are complete washouts, but neither should you expect uninterrupted sunshine. There are about 6.4 hours of sunshine within 11.8 hours of daylight, giving you scope to spend time outside without assuming every daylight hour will be sunny.
