Your March weather guide
MildWeather in Costa Brava in March
Costa Brava in March suits a break with walks and time outdoors, rather than a warm beach holiday. Average daytime highs are around 16°C, but nights fall to 7°C and the sea is cold at 13°C. Go if you are happy wearing layers and adjusting your plans around rain. It offers milder afternoons than London, but not reliable warmth for sitting outside all day or spending much time in the water.

How March compares
March is the 9th warmest month of the year in Costa Brava. Within Spain it is 68th of 87 (Spain in March). Against London's average high of 10.5°C in March, Costa Brava is 5.4°C warmer by day and 3.7°C warmer at night.
Daytime and night-time in March
The typical March day in Costa Brava peaks at 15.9°C, but that is an average: the warmest 10% of days reach 19.6°C or more. Roughly 1 in 1000 days top 25°C. Nights average 7.0°C; one night in ten drops to 3.6°C or lower, so pack a layer for evenings - it is genuinely cool after dark. Between 1991 and 2020 the hottest March day here reached 25.5°C (2001-03-23) and the coldest night -4.2°C (2010-03-11).
Rain in March
Wet (more than 8 rainy days): about 8 days with 1 mm or more, 57 mm in total. Year to year it varies a lot - the wettest March was 2013 with 137 mm, the driest 1997 with 6 mm. Humidity averages 75%.
Sea temperature in March
The sea averages 13.0°C - too cold for most (under 18°c). Depending on the year it ranges from 12.5°C to 13.5°C. For the warmest sea here, come in August (24.8°C).
Sunshine and daylight
Around 5.7 hours of sunshine a day (estimated from cloud cover), 11.7 hours of daylight: the sun rises about 07:00 and sets about 18:55 local time in mid-March. Average cloud cover is 51%.
Is March a good time to visit Costa Brava?
March is not the strongest month here: mild days and frequent rain. The best months for Costa Brava on our scoring are July, June, August; months averaging 25°C or more: Jun, Jul, Aug.
Mild afternoons, but pack for cold evenings
The daytime average makes March comfortable for walking without summer heat, though it is not a promise of shirtsleeves weather. Warmer days can reach around 20°C, so removable layers make more sense than a heavy outfit you cannot adjust. The catch comes after sunset: average nights are cool, and the coldest can fall to around 4°C or lower. Bring a jumper, a jacket and long trousers rather than packing mainly for the warmest afternoon. Plan your longer spells outdoors for the warmer part of the day, and keep something warm with you if you expect to stay out into the evening.
Allow for rain and treat the sea as scenery
Rain is a real planning consideration, with about 8 rainy days during March. A waterproof jacket and footwear that can handle wet pavements are sensible, and a flexible schedule will serve you better than plans that depend on dry weather throughout. There is still useful outdoor time: around 5.7 hours of sunshine within 11.7 hours of daylight on average, although that does not guarantee a sunny spell each day. The sea is the clearer limitation. At 13°C, it is cold rather than merely refreshing, so March does not suit a holiday built around comfortable swimming. Choose it for time beside the water, not warm-water bathing.
