Comfortable daytime weather, but pack for cool evenings

March suits travellers who prefer walking and spending time outside without relying on strong heat. The average daytime high is 9.1°C above London's March figure, so the difference should feel noticeable, especially in sunshine. Light clothes may be comfortable during warmer afternoons, but bring a jumper, long trousers and a jacket rather than packing only for summer. The warmest days can reach 24.4°C or more, while the coldest nights fall to 6.8°C or below. That contrast makes flexible layers more useful than a suitcase built around the daytime average. Plan relaxed outdoor time around the warmer part of the day, with warmer clothing ready for dinner and evenings.

Useful sunshine, some rain and a cold sea

There is enough sunshine to make outdoor plans worthwhile: March averages about 6.9 hours a day within 11.7 hours of daylight. That does not mean clear skies throughout your stay, and about 6 rainy days in the month make a light waterproof a sensible addition. Keep your plans flexible rather than assuming every afternoon will be suitable for sitting outside. The bigger limitation for a beach-focused trip is the sea, averaging 14.8°C. Even its year-to-year range of 14°C to 16°C stays firmly cold, so do not book March expecting comfortable sea swimming. It is a better fit for time beside the water in pleasant weather than for a holiday centred on being in it.
