With an average of 318 mm per year, rainfall is low. There is drought in summer with only a few storms in the late afternoon.
In July and August, temperatures are typically above 30°C (86°F), reaching up to 40°C (104°F) a few days per year.
In winter the temperatures are low, usually between -4ºC and 10°C, with frosts during the night. Snow occurs only once every year, and fog is common (about 20 days from November to January) and the temperature won’t be higher than 0-3ºC with fog, frosting at night.
However, the worst part is the Cierzo (strongest wind in Spain), a cold and dry wind blowing from the NW that is quite common on clear days and can make your stay really unpleasant. Beware also of sunny days in spring and autumn, if the Cierzo blows, you will regret not having warm clothes with you.
Be especially careful with cierzo in winter, since on some cold waves thermal sensation has been as low as -15ºC due to its high speed.
