The northern plains see extremes of temperature. Baking summers (up to 43°C) and freezing winters (occasionally down to -10°C) lead Mazar-e Sharif’s citizens to joke about their paka o posteen (‘fan or furcoat’) climate. Spring and autumn are thankfully more temperate. Faizabad has a more moderate climate, although winter snows make travel in Badakhshan problematic between October/November and March/April. The high altitude Wakhan Corridor has warm days and near freezing nights even at the height of summer in July, while early snow effectively cuts the region off from the rest of Afghanistan from late September.
