Comfortable days, with a sharp drop after sunset

The daytime average makes March well suited to travellers who prefer being active outdoors without strong heat. A light top may be enough during warmer spells, but keep a jumper handy rather than packing only summer clothes. Days reaching 25°C account for 11% of the month, while 30°C is much less common at 2%, so hot weather is a bonus rather than the basis for booking. Evenings need a different approach: the coldest nights can fall to around 6°C or lower. Bring a jacket and long trousers if you want to stay comfortable outside after sunset, and choose layers you can remove as the day warms.

Useful sunshine, but leave room for rain

March brings about 7 hours of sunshine a day within 11.7 hours of daylight, giving you a useful amount of time for outdoor plans. That is not a promise of clear skies throughout your stay, though. There are about 6 rainy days in the month, so a light waterproof is a sensible addition to your bag. Keep your schedule flexible enough to move outdoor time around wetter weather rather than treating every day as a beach day. The balance suits travellers happy to make the most of sunny periods and adjust when conditions change; it is less suitable if uninterrupted sunshine is essential.

Better for time by the sea than time in it

The sea is the main catch if you are considering March for a beach-focused trip. Its average temperature is 14.8°C, with a year-to-year range of 14°C to 16°C, so even a warmer year leaves it cold for swimming. Sitting by the water may appeal when the air feels warm, but do not confuse a pleasant afternoon with comfortable bathing conditions. If swimming is central to your holiday, March is a poor fit. If you mainly want fresh air, walks and some daytime warmth, the trade-off is easier to accept. Pack for time outdoors, with warm layers for cooler moments, rather than relying on swimwear.
