Beware of preconceived ideas!
A mild climate and temperatures influenced by the ocean
A total of 1,700 hours sunshine per year
Dominating south-westerly winds
Rainfall of oceanic origin, particularly on the relief


Normandy's climate is characterised by a temperate oceanic influence: rainfall, temperature and wind are largely dependent on the agitated Atlantic current. However, major variations are observed between coastal and inland territories and depending on relief.


Rainfall: most often oceanic, rain falls initially on the relief. In the Bocage and to the north of the Cotentin, an average of over 1,100mm of rainfall is observed each year.
Further east, the hilly Pays d'Auge is also subject to abundant rainfall with a yearly maximum of up to 900mm. In the more protected plain stretching from the Orne estuary to the Pays d'Argentan, less than 800mm of rain falls each year.


Wind: dominating south-westerly winds. The west coast of the Cotentin peninsula, together with the more exposed northern headlands, are subject to the strongest winds, particularly in the winter. An average of 130 days of strong wind are recorded in the La Hague region, compared to only 27 days in Alençon. In spring and summer, the coast is regularly subject to the sea breeze, contributing to improved sunshine.


Temperatures: thermal conditions are also largely dependent on coastal proximity. Coastal regions are generally spared the harshest of winter conditions and freezing is both rare and short-lived.
Thermal amplitude is low and periods of freezing are short. These relatively mild temperatures also concern the Bessin and the Caen plain despite certain striking contrasts. In the Bocage, the Pays d'Auge and in the Perche region, together with the Alençon and Argentan basins, a continental climate combined with the presence of changing relief results in heterogeneous temperatures: the eastern slopes are subject to earlier (autumn) and later (spring) periods of freezing which are also more frequent than in western zones; winters are generally colder, but summers are also warmer with maximum temperatures above 25°C recorded over 30 days per year.


Despite its image as a particularly rainy region, Normandy in fact benefits from excellent levels of sunshine with an average of 1,700 hours per year.
