The climate in Italy

Average daytime and nighttime temperatures


All climatic diagrams of this page are taken from the collected data from 45 measuring stations in Italy.
Weather stations at an altitude above 2130m 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.

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 September. Nearly unattractive for tourists are the cold months from November to March.

Temperature records of the last 70 years

The hottest temperature measured from 1949 to March 2019 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 51 weather stations in Italy below 2130 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 22.7 degrees Celsius.

The coldest day in these 70 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 5.9 °C. In Italy, it is usual to have about 2.0 degrees more at 7.9 °C for this three-month period.


Long-term development of temperatures from 1990 - 2019

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 2019 there were only these 3 weather stations in the whole country, which reported continuous temperature values (Triest, Messina, 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 August 2003 with 28.0 °C. Februar 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 2019. So over the past 30 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.
