It’s advisable to stay hydrated and seek shade or air-conditioned environments when the humidity levels are high. Particularly during the hottest parts of the day.

Record Temperatures in Italy

In August, Italy experienced notable temperature records and rainfall. Let’s explore some of the highest and lowest temperatures ever recorded in August and rainfall occurrences.

One of the highest temperatures on record for August in Italy was registered in Sicily. This occurred on August 11, 2021, in the town of Floridia, located in the Sicilian province of Syracuse. During that sweltering day, it reached a record temperature of 48.8 degrees Celsius (119.8 degrees Fahrenheit). This record-breaking heatwave was part of a broader extreme weather event that affected various parts of Europe.

On the other end of the spectrum, though it’s difficult to pinpoint the coldest temperature recorded in August, the coolest temperatures generally occur in the Italian Alps. In the Alpine town of Livigno, for example, the temperature regularly drops 4.5 degrees Celcius (40 degrees Fahrenheit) throughout the summer. It’s important to note that low temperatures are exceptional for August and are mainly isolated to the mountainous areas.

Rainfall in Italy

Amongst Italy’s August weather, the country is known to have little rainfall. However, the average rainfall across Italy varies depending on the region and time of year. Similar to Greece, Italy experiences a Mediterranean climate characterized by mild, wet winters and hot, dry summers.

In general, the northern regions of Italy receive more rainfall compared to the central and southern parts of the country. The mountainous areas, such as the Alps and the Apennines, contribute to the increased precipitation levels in the north. Cities in northern regions experience a higher average annual rainfall compared to towns in the central and southern parts of Italy.

Northern Italy

On average, the northern regions of Italy receive around 800 to 1,200 millimeters (31 to 47 inches) of rainfall annually. Some areas can receive upwards of 2,500 millimeters (98.5 inches). The general average translates to an average monthly rainfall of approximately 60 to 100 millimeters (2.4 to 3.9 inches). The rainfall in the north is relatively evenly distributed throughout the year. Higher precipitation occurs in the spring and autumn months.

Central Italy

Moving towards central Italy, including cities like Rome and Florence, the average annual rainfall decreases. In these regions, the average annual rainfall ranges from about 600 to 900 millimeters (24 to 35 inches). Monthly averages can vary from 40 to 80 millimeters (1.6 to 3.1 inches). The wetter period is during the autumn months.

Southern Italy

The southern parts of Italy, such as Naples and Sicily, experience a Mediterranean climate with drier summers. The average annual rainfall in these regions ranges from approximately 400 to 700 millimeters (16 to 28 inches). Monthly averages can range from 20 to 60 millimeters (0.8 to 2.4 inches).
