Good for outdoor plans, with a wet-weather fallback

March gives you enough daylight for unhurried days out: about 11.6 hours, with around 5.4 hours of sunshine on average. That leaves scope for pleasant spells outdoors, but sunshine is not an all-day promise. The warmer days reach around 16°C or more, so removable layers make more sense than dressing for constant cold. Rain is the catch rather than heat: with about 8 rainy days, it is sensible to keep indoor options flexible instead of committing every day to being outside. A waterproof outer layer is useful, and shoes that cope with wet conditions will make a damp day less of a nuisance.

Pack for cold evenings, not swimming

The drop in temperature after daytime outings is the main reason not to pack too lightly. Average nights are around 5°C, while the coldest nights fall to about 2°C or below. Bring a warm layer beneath your coat, and keep it with you if you expect to stay out into the evening. March is also a poor choice if swimming matters to your holiday: the sea averages 9.8°C, firmly in the cold category rather than merely bracing. Treat time beside the water as a clothed outdoor activity. This month works best for travellers who prefer cool conditions and do not need their break to include beach weather.
