Average weather, temperature, rainfall, sunshine hours
In Lugano, located in the canton of Ticino, on the shores of the lake of the same name (also called Ceresio), 270 meters (885 feet) above sea level, the climate is
humid temperate. Winters are quite cold, while summers are warm to hot, and characterized by a good amount of sunshine, but also by quite frequent thunderstorms. Along with Locarno, Lugano is the mildest city in Switzerland.
In the cold half of the year, the
wind is generally weak or absent, except when the
favonio (or
föhn) blows, the warm and dry wind that comes down from the Alps and is able to bring clear skies and very good visibility.
In the warm half of the year, the wind is weak or moderate and follows the
breeze regime: during the warmest hours, the breeze blows from the lake towards the mountains, while after sunset and at night, it blows from the mountains to the lake.
The
average temperature in January is around 4 °C (39 °F), while in July it is around 22.5 °C (72.5 °F).
Rainfall in Lugano is abundant, since it amounts to 1,550 millimeters (61 inches) per year. Winter is the relatively driest season. In spring and autumn, the rains are plentiful in periods of Atlantic depressions, since the southern currents are forced to rise over the Alps and condense. In late spring and summer, thunderstorms in the afternoon or evening are quite frequent (and sometimes intense). During the most intense waves of bad weather, which occur in autumn (but sometimes also in spring), the lake may overflow, flooding the lower areas of the city.
Winter, from December to February, is cold enough, but owing to the mitigating influence of the lake, it is milder than in the major cities of Switzerland, and it's also milder than in the Po Valley. Fog is less frequent as well.
There is a moderate amount of rainy days, even though the winter is the driest season.
Snow generally falls at least once every year, and it can sometimes be plentiful (for example, on January 27, 2006, 72 centimeters (28.5 inches) of snow fell), but it tends to melt soon enough because it occurs in conditions of southerly winds. In a year, an average of 26 cm (10.2 in) of snow falls. The record belongs to the winter of 1977/78, when a total of nearly three meters (10 feet) of snow fell.
We can not exclude
very cold periods, with night frosts and temperatures around freezing or even below in the daytime. However, in these cases, the weather is usually dry. It's rare for the temperature to drop below -5 °C (23 °F), even though it can happen on colder winters. The coldest record is -14 °C (6.8 °F) and was set in February 1929.
Summer, from June to August, is warm to hot, and often sunny in the morning. The temperature is generally pleasant or at least bearable, in addition, there is some wind because of the lake breeze. Sometimes, an Atlantic front, able to bring some cool and rainy days, can affect this area; more often, thunderstorms can break out in the afternoon or in the evening.
Very hot days are quite rare, however, in recent decades, due to global warming, they have become more frequent. The highest record is 38 °C (100.4 °F) and was set in July 1945. In 2022, the temperature reached 36 °C (97 °F) in both July and August.
The amount of
sunshine in Lugano is acceptable in winter, when there are sunny days alternating with cloudy periods; in the other seasons, it is not very high, in fact, Atlantic disturbances pass over the area quite frequently in spring and autumn, while in summer, in periods of good weather, cloudiness in the afternoon can form, which can lead to thunderstorms.
Best Time
The
best periods to visit Lugano are spring and early summer, in particular, from mid-April to mid-June. September, too, is a good month. However, you have to take into account some rainy days in both periods.
Summer, which is the best time for sunbathing, can be hot, though this rarely happens: the temperature is usually acceptable, especially in June. As mentioned, in summer and in May, thunderstorms can break out in the afternoon or in the evening.
