Climate of the Pas-de-Calais

The Pas-de-Calais is a department classified under oceanic Climat.

Of share its position, the Pas-de-Calais is subjected to various climatic influences: time is known as " variable" but the sea protects from any climatic excess.

The relief and the position of the department compared to great flow differentiate the climate from one end to another of the area:

the influence Atlantic in flow of west often involves the birth of the typical ciels of drag of the area.
the influence of flows of east can cause cold winters under an immaculate blue sky or sunny summers.
flows of south bring in summer an air drained by the overflight of France and the interior of the area can then approach the 40°, as at the time of the summer 2003.

The most sprinkled zones are the zones of reliefs, especially if they are wooded. The west is exposed to the marine winds dominating of south-west: if the variation in temperatures are attenuated, the Highland of Artois is for example the most sprinkled zone department, with 1000 mm/an. In the center of the department, the hills of Artois receive approximately 800 mm/an. This office plurality falls to 600 mm/an on the north-eastern slope, protected from the dominant winds, with an estival average temperature slightly higher than 23°. One thus observes a contrast in precipitations, with zones of relief in the west relatively sprinkled whereas certain areas of plains are as dry as the Riviera.

The average Température in Hiver rises with 2°C, and in be with 26°C. At the time of dryness, the temperatures can reach the 35°C, and at the time of rigorous winters -3°C. In the Pas-de-Calais, it rains 159 days per annum is 44% of the year.
