Lake Como sits in northern Italy’s Lombardy region at 199 metres (653 feet) above sea level, surrounded by the Prealps. The lake creates its own microclimate: winters are milder than inland Milan and summers are warm without the oppressive humidity of the Po Valley. Daytime highs range from 7°C (45°F) in January to 28°C (82°F) in July, with annual rainfall around 1,200mm spread across the year. The lake water temperature peaks at 24°C (75°F) in August and drops to 8°C (46°F) in February. Explore our complete Lake Como guide for everything you need to plan your trip.
