Moderate sea, soft enough. Average annual temperature is about 12 C, in January - from +3 C on the coast to -1 C in the Ardennes, in July - 14-18 C. In this case are often times when the weather is "knocked out" the framework of the seasonal rhythm - often come in the summer of cool moist winds from the Atlantic, bringing the long rains and relatively cool weather and in winter these same marine cyclones bring warm and wet weather. Precipitation occurs mainly in autumn-winter period in the form of rain (from 700-900 mm. Lowland areas up to 1200-1500 mm. In the mountains). Relative humidity is high enough all year round.
