What's the weather like in Costa Brava in September?The Costa Brava’s a coastal region in the northeast of Spain and has quite typical Mediterranean weather. Its location means the area does have slightly cooler and wetter weather than other destinations on the Spanish coast. Costa Brava gets more rain in September as the month goes on although you'll still get plenty of sun if you're going at this time. The Pyrenees mountains will give you some shelter from wind and rain, and they also send the cool tramuntana winds down to the coast. You can have different weather from bay to bay on the Costa Brava because of the mountains and the area can also be affected by weather systems that come over from Europe, the Atlantic, the Mediterranean and North Africa.

There’s 39mm of rain over ten days, and you can expect 12 hours of daylight with six hours of sunshine each day.
