Weather on our Mountain Trips in the Pyrenees

Mountain weather is notoriously unpredictable and the Pyrenees are no exception!

Generally, in this part of the range, winds blow from the humid Atlantic north, creating cooler, cloudier and wetter conditions on the French side. The southern-facing Spanish side, where most of our walking takes place, sits in the rain shadow and enjoys a much better climate, usually dry and sunny during the summer, although during July and August thunder storms often develop late in the day.

The very best months to come are probably from early June to mid-July when the conditions are typically the most stable, temperatures are pleasant and most snow has usually melted from the highest parts of our trails. There are also tons of flowers! Late July and August are hot although cool at night. September is cooler and increasingly wetter, while October can be quite wet and is usually the limit since soon snow will begin to fall at the higher elevations.

Remember that on most routes you will usually be hiking well above the overnight bases (see below) and therefore temperatures will be considerably cooler and rainfall will be more frequent and heavier. In addition, higher up it will inevitably be windier (and therefore increasing the sensation of cold “windchill factor”).
