What's the weather like on the Costa Brava in March?With its Mediterranean climate on the southeast coast of Spain, the Costa Brava has short, cool winters and long, hot summers. In March, spring brings slightly warmer weather after a cold winter season, with rising mild temperatures, less rain and more sunshine. Although it’s not beach weather at this time of year, March is a good month for exploring the Costa Brava away from the high season crowds.
AveragesOn average, temperatures on the Costa Brava in March hover around 11°C, with highs of a pleasant 18°C at the peak of the day. At night temperatures drop to a low of 4°C, so although the afternoons can be warm enough for t-shirts, you’ll need a jumper and jacket for evenings out at the local bars and restaurants. At this time of year, the Mediterranean waters are a chilly 14°C, so you’ll need to be very brave if you want to take a dip in the sea. Just 45mm of rain is expected this month, falling across an average of eight wet days.
