 Conversely, in those brief episodes when the southwestern winds blow through the mountains (especially during October–November), the effect reverses, the northern coast gets inside the Foehn winds and is dry and much warmer than the inner plateau, where rain is present.The average precipitation is about 1,200 mm, higher than in most areas in inland central Europe, and wetter than almost anywhere in Spain, a country generally considered dry (the main exception to this northernly rainfall trend is the Sierra de Grazalema, in the southern province of Cádiz, with mountains that block the Atlantic moisture-carrying winds and which is, indeed, the most rainy place in Spain).Asturias has an average summer temperature of 20-22 °C, being one of the mildest climates in Europe.
