Although this is a mainly dry area, we can have torrential rain even in the summer. From time to time the Pyrenees also has a very strong, dry wind , the Tramontane, although this is much less frequent in Serralongue than nearer the coast.
We are, however, much further south than Great Britain (the next village is the most southerly commune in mainland France!), and the sun is higher, so sensitive skins can burn, even in winter!
As for eating out, etc, this area is very relaxed, and there is no need to dress up, even for very good restaurants.
Jeans or shorts are acceptable anywhere, anytime.
There is a Meteo France weather station in Serralongue, so for a really close look at our weather see Serralongue weather
