Weather  with a dramatic difference in weather between the summer and winter months, the Pyrenees are best visited between June and September (unless you’re there for the skiing!).  In the lowlands to the north of Lourdes the winters can be surprisingly mild (see chart).  But in the mountains the winters are severe and throughout the year you should be equipped in case of poor weather, remembering that as you climb the temperature can drop significantly.  You will find the weather in summer can be surprisingly warm although the western Pyrenees do get influenced by precipitation coming off the Atlantic.  For an up to date weather forecast, select here.
