Rome’s climate is Mediterranean and mild, which means that any time of year is good for visiting the city.
If we compare the climate of Rome to that of London, Dublin, Amsterdam or other northern European cities, temperatures are much more pleasant throughout the year and are between 2 and 10ºC higher, depending on the season. Rome’s climate is much warmer than New York or San Francisco.
Autumn and winter precipitation levels are higher than in London.
Rome’s coldest months are January and February. At this time of year, low temperatures are around 5ºC, and can reach freezing temperatures at night. During the day, the temperature is usually fairly pleasant.
July and August are the hottest months of the year, with average high temperatures of 30ºC. Due to the high humidity, on some summer days the felt air temperature can be quite overwhelming.
In August, some businesses that are not associated with tourism close down to beat the city heat.
Although any time of year is great for visiting Rome, if you have the chance, it’s best to go in the spring or autumn. There are fewer tourists and the temperature is more pleasant. Of the two seasons, rain is less likely in the spring.
