Nights average 3.5°C; one night in ten drops to -0.3°C or lower, so pack a layer for evenings - it is genuinely cool after dark.

Pack for chilly evenings, not just mild afternoons

The daytime average is mild enough for walking in a coat, but it does not tell the whole story. The warmest days can reach 17.4°C or more, while the coldest nights fall to -0.3°C or below. Wear layers you can remove if an afternoon turns mild, and keep a warm outer layer for heading out after dark. A jumper, long trousers and closed shoes are more useful than clothes chosen for heat. March is a reasonable choice if hot city weather puts you off, but less convincing if you want to sit outside comfortably without thinking about what to wear.

Leave room to change plans when it rains

Rain is a meaningful part of the March trade-off, so avoid making every day depend on staying outdoors. Carry a compact umbrella or waterproof jacket, and choose shoes that can cope with wet pavements. There are about 4.9 hours of sunshine within 11.7 hours of daylight: enough daylight for unhurried outings, but not a promise of bright skies throughout. Keep outdoor plans flexible and have an indoor alternative ready when conditions turn wet. This month works better for travellers who can adjust their day than for those whose main priority is reliable sunshine or spending most of their time outside.
