Austria enjoys a temperate Central European climate with four distinct seasons. Summers, between June and August, are hot with cool nights. In Vienna and other low-lying cities, temperatures during the day can get uncomfortably hot over July and August. Winters are cold and below freezing in January and February. The ski season in the Alps runs from December to April but the mountains are also popular with hikers and climbers over the summer when the weather is usually warm and bright.
