The climate in Italy

Average daytime and nighttime temperatures

All climatic diagrams of this page are taken from the collected data from 83 measuring stations in Italy.
Weather stations at an altitude above 3490m have not been included.
All data correspond to the average monthly values of the last 20 years.

Back to overview: Italy

Climate zone: The northern part of Italy is located in the temperate climatic zone, while the southern part is subtropical.

The climate in Italy widely corresponds to the German weather conditions. It is cold, wet and a few beautiful summer months are also happening. A beach holiday can be enjoyed in the warmer season with water temperatures up to 25 degrees. Due to the warmer temperatures the best time for traveling is from June to August. Nearly unattractive for tourists are the cold months from November to March. Days with heavy rain and large amounts of precipitation are in July.

Temperature records of the last 72 years

The hottest temperature measured from 1949 to June 2021 was reported by the Palermo Bocadifalco Sicilia weather station. In August 1999 the record temperature of 45.2 °C was reported here. The hottest summer from July to September, based on all 55 weather stations in Italy below 3490 metres altitude, was recorded in 1987 with an average temperature of 24.5 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 22.3 degrees Celsius.

The coldest day in these 72 years was reported by the weather station Dobbiaco. Here the temperature dropped to -23.0 °C in March 2005. Dobbiaco lies at an altitude of 1226 meters above sea level. The coldest winter (January to March) was in 2005 with an average temperature of 5.5 °C. In Italy, it is usual to have about 2.0 degrees more at 7.6 °C for this three-month period.

The most precipitation fell in Februar 2005. With 357.1 mm per day, the Monte Terminillo weather station recorded the highest monthly average of the last 72 years. Incidentally, the region with the most rainfall for the whole year is around Capo Palinuro. The driest region is near Termoli.

Long-term development of temperatures from 1990 - 2020

In contrast to single record values, a long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would give a falsified result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would already decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and falsifies the average again. The subsequent long-term development was therefore reduced to only 3 measuring points in order to have actually comparable data over as long a period as possible.

In the years 1990 to 2020 there were only these 3 weather stations in the whole country, which reported continuous temperature values (Messina, Triest, Trapani Birgi). From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was 2003 with 28.0 °C. 2003 was the coldest month with an average temperature of 7.1 °C.

The average annual temperature was about 17.3 °C in the years after 1990 and about 17.7 °C in the last years before 2020. So over the past 31 years it has only increased by a minimal 0.4 °C. This trend only applies to the selected 3 weather stations in Italy. A considerably more comprehensive evaluation of the global warming has been provided separately.
