The wind is quite common, and can increase the sensation of cold.

Winter, from December to February, is relatively mild. At night the temperature is normally around freezing (0 °C or 32 °F), while during the day it's about 10 °C (50 °F). However, there may be variations depending on the weather situation: cold winds from the north or east can bring snowfall and frost; for instance in February 2012 the temperature dropped to -11 °C (12 °F). On the other hand, when the winds blow from the ocean, the temperature gets milder, though with quite frequent rains.

Spring, from March to May, is cool and quite rainy. Temperatures can change quickly, and the first mild or even warm days, alternate with quite cold days.

Summer, from June to August, is mild or pleasantly warm, with cool nights. In periods of good weather, during the day it can get hot: the temperature can reach and exceed 30 °C (86 °F); very hot days are rare, but sometimes it can reach as high as 35 °C (95 °F) and even above. In the afternoon, thunderstorms may erupt, usually of short duration, while some occasional Atlantic disturbances can bring some cool and rainy days, also in mid-summer. After all, due to Atlantic fronts and afternoon thunderstorms, it rains on average for 10/12 days per month in summer as well.

Autumn, from September to November, is initially mild, in fact in September there may still be some summery days. But with each passing week, it gradually becomes more cool, cloudy and rainy.

The amount of sunshine in Lourdes is decent, but not great, all year round: good weather is more frequent in summer, but in the afternoon the sky can become cloudy, while in the other seasons, disturbances pass often enough.




The best time to visit Lourdes runs from June to September, being the warmest and driest of the year. May and October, though rainier, may be fine too, although sometimes it can get cold, especially in the first half of May and in the second of October. Those who cannot stand the heat, to avoid the albeit rare hot days, can choose May, September and October.
