Lake Como is known for its relatively mild weather. Average daily temperatures range from about 2 °C (36°F) in January to 30°C (86°F) in July. Due to the unusual micro-climate of Lake Como, the summers tend to be long and winters are short and mild. Summer conditions can begin as early as May. However there can be a lot of rainfall in May so make sure you bring a rain jacket. The holiday season runs from Easter to October. Ideal times to go are May, June and September/October when it is still warm and sunny but not as crowded (or as hot) as in the midsummer months. Rainfall is consistent across the year, with spring and autumn being the wettest periods.
Springtime in Lake Como is a beautiful sight to witness as the trees and flowers bloom. During this season you will experience torrential downpours which can last for a couple of days but the consecutive days thereafter are usually clear and sunny.
Although the summers can be hot, they are bearable, as there is usually a gentle breeze therefore making it slightly cooler than the cities. You also have the added bonus of having the lake to cool off in. Summers will see the odd day when the mercury rises over 30°C, but in the peak summer months the temperatures tend to hover in the high 20’s. Water temperatures can reach an average of 24°C (75°F) during the month of July.
Autumn is a great time to visit Lake Como as it is usually a lot quieter than in the summer months and the weather is still mild and pleasant. There is rainfall during the autumn season but nothing compared to the UK. The changing colour of the vegetation on the surrounding mountains is a beautiful sight to behold; from golden yellows, oranges and reds to brown. It is also quieter at this time of year compared to the summer months .
Winters are rarely bitterly cold as the surrounding mountains act as a barrier in keeping Lake Como warmer than other locations at similar latitudes. However the valleys can funnel chilly winds from the alps in the winter and there are more foggy days during this period where you are unable to see the lake but don’t despair, as you also have lots of crisp clear blue skies during the winter months too. Snowfall is erratic and primarily affects the higher ground. There is less rainfall during the winter months. The temperature can drop below freezing ( -3°C) with January being one of the coldest months.
