December through February are the coldest months in Rome. The average daytime high is 7.5 - 8.4°C, while the standard low is 3.5°C. There are generally a few snow days during the winter, but accumulations are uncommon and the snow does not often stay very long.
While this will leaving you warming your feet by the fire in the evening, there are distinct advantages to a winter holiday in Rome. The prices of everything are lower, including travel fares, hotel rates and restaurant prices. Queues for visiting the museums and other attractions are much shorter and you’ll be able to cover a lot more ground than you can in busier times. Some restaurants are impossible to get into without reservations, but your waiting period for a reserved table will be much shorter during the winter.
Rome is humid during the winters, with the heaviest rainfalls during the months of October through January. However, those heavy rains have begun tapering off by February, leaving many clearer, sparkling days than overcast, moody ones.
March moves in with warm, gentle days and blossoming gardens and parks. The ideal time to visit Rome is during these delicious spring months between March and May, when clouds have drifted off to torment someone else for awhile, and high temperatures have not yet reached the boiling point. There are some beautiful beaches just an hour away from Rome, but the beach crowd hasn’t put on its sun-bathing gear yet. You’ll find the beaches comfortably settled into a small communities of sun worshippers and early swimmers.
It’s an excellent time to stroll the Via Appia (the Appian Way), one of the earliest and strategically, one of the most important roads in the early Roman Republic. There’s a feeling of solitude and communion with nature, as birds call cheerily from newly unfurled trees and flowers poke their heads up in celebration of spring.
Spring time temperatures average between 13 - 18°C, perfect weather for long excursions and exploring all the astounding landmarks the city has to offer. With over 2,500 years of active history, there is much to see.
Although spring had been considered a shoulder season, with travel accommodations offering some of their best traffic deals, in recent years, spring has become prime time for experienced visitors. They take advantage of the warm days and cool nights to linger among their favourite attractions. Also, the Lenten Season is a huge factor in Rome. Every year, thousands of Christians flock into Rome during the Easter holiday to visit the churches and take part in Easter ceremonies. As a result, it can actually be more difficult to find a holiday deal during the spring than it can be during the peak season.
Although March and April are on their way up as favoured months for a holiday, the peak season is still from May to . May begins gently enough, following April’s spring time weather with comfortable 23°C temperatures. The chances of rain begin tapering off, and that evening jacket doesn’t have to be anymore than your favourite zip-up.
There are a lot of festivals in May that begin with Labour Day on the first of the month. Romans will either head out of town for their own holiday or stick around for the huge concert in Piazza San Giovanni, which usually begins in the early afternoon and continues until after midnight. There are also special open house tours of the buildings and architecture in Rome, museum nights and tennis tournaments. May sixth, a new group of Swiss guards are sworn in at the Vatican, marking the date of the 1506 sack of Rome.
Some like it hot during the summer months, and though Rome’s summer heat doesn’t compete with tropical weather, June through August get hot enough to make that Italian gelato in a shaded outdoor café look like a small piece of heaven. As the summer gets dryer, it gets hotter, pumping out temperatures of 28°C and higher. Evenings cool down to 23°C, making that sweater just an extra precaution.
You can receive many hotel and travel deals in August, but if you don’t like the heat, you might find yourself spending more time trying to think of ways to cool off than in actually enjoying your holiday. Nor are you left with as many options for shopping and dining. Romans use this crackling month when temperatures are often well over 30°C to plan their own excursions to cooler climes.
The peak tourist season for Rome officially ends on September first, but it doesn’t mean an end to holiday weather. The first part of September is usually as hot and dry with August, with consistent drops in the temperature until by October, you’re coasting along in agreeable 23°C once more. Like the spring, however, September and October have become popular times for choosing a holiday in Rome. The thongs that characterize Rome’s summer have not depleted substantially and Romans have returned to their businesses and homes.
Nighttime weather is chilly in the autumn, averaging out around 6°C, so you will want warm clothing for the evenings. Rain is infrequent until October, when the wet season begins moving in. It’s difficult to know what the weather will be like from one day to the next in November. Some days could be filled with sunshine, while the following week, chilly and gloomy. The rainiest months are November and December, and you need to be prepared for downpours. The weather becomes progressively cooler, making it advisable to pack plenty of warm clothing and rain gear.
