Your March weather guide
MildWeather in Andalucia in March
March is a good time for Andalucia if you want milder weather for getting out and about, rather than a hot beach holiday. Average daytime highs are 17.5°C, around 7°C warmer than London, while nights average 10.3°C. For a UK traveller, that makes it a useful change from home without much risk of uncomfortable heat. The catch is that rain remains part of the picture, evenings need layers and the sea is cold.

How March compares
March is the 9th warmest month of the year in Andalucia. Within Spain it is 38th of 87 (Spain in March). Against London's average high of 10.5°C in March, Andalucia is 7.0°C warmer by day and 7.0°C warmer at night.
Daytime and night-time in March
The typical March day in Andalucia peaks at 17.5°C, but that is an average: the warmest 10% of days reach 21.0°C or more. Roughly 1 in 59 days top 25°C. Nights average 10.3°C; one night in ten drops to 7.7°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 31.3°C (2020-03-11) and the coldest night -0.9°C (1993-03-02).
Rain in March
Some rain (4-8 rainy days): about 7 days with 1 mm or more, 59 mm in total. Year to year it varies a lot - the wettest March was 2018 with 386 mm, the driest 1997 with 0 mm. Humidity averages 72%.
Sea temperature in March

Sunshine and daylight
Around 6.3 hours of sunshine a day (estimated from cloud cover), 11.7 hours of daylight: the sun rises about 07:35 and sets about 19:31 local time in mid-March. Average cloud cover is 46%.
Is March a good time to visit Andalucia?
March is not the strongest month here: mild days. The best months for Andalucia on our scoring are July, August, June; months averaging 25°C or more: Jun, Jul, Aug, Sep.
Comfortable for exploring, but pack layers
The mild daytime temperatures suit travellers who prefer walking around without strong heat. Warmer days can reach 21°C or more, so take a light top for those spells, but do not pack as though summer has arrived. Only 2% of days reach 25°C, making reliable sunbathing weather an unrealistic expectation. A jumper and jacket will be more useful than a suitcase built entirely around shorts. The coldest nights can fall to 7.7°C or lower, so keep a warmer layer handy if you plan to stay out after dark. March works best when you value comfortable daytime activity more than warm evenings outdoors.
Leave room for rain and treat the sea as cold
Expect some weather interruptions rather than assuming every day will be dry. There are about 7 rainy days in March, so a waterproof jacket and flexible plans are sensible. That still leaves scope for time outdoors, with about 6.3 hours of sunshine within 11.7 hours of daylight, but sunshine is not guaranteed throughout the day. Use brighter spells for longer walks and be ready to rearrange outdoor plans when rain arrives. The sea averages 15.2°C, which is cold rather than comfortably swimmable. If your holiday depends on relaxed sea swimming and long stretches in swimwear, March is not a strong fit; it makes more sense for a mixed-weather break.
