Revealing the Weather in Rome

Rome has a warm, dry climate with well-defined seasons. Winters are mild, and what Romans call "bitter cold" is around 30 degrees Fahrenheit, which rarely happens during the day. In summer, the weather is hot, maybe not as humid as it gets in, say, Washington, D.C., but still rather unpleasant, particularly if you're sensitive to heat. Also, many attractions are outdoors, where you can't resort to air conditioning (which, by the way, more times than not will not work as well in your hotel room as at home).

Rome in August is crowded with tourists and lines, and unbearably hot. All the locals have gone out of town, including shop and restaurant owners who often take at least two weeks off in August, if not the entire month. July isn't much better temperature-wise, but at least most restaurants and shops are open.

Most of the rain usually falls in the late fall and winter (it rarely snows in Rome — maybe once every ten years), with November usually being rainiest. Heavy and brief thunderstorms are common, not only during the fall and winter, but also in the spring and summer (particularly in August), and the occasional rainy day can happen all year around but particularly from fall to spring.

Here are the pros and cons for traveling in each season.

April through June

Spring and early summer are the most pleasant times to visit Rome:

Temperatures are moderate, and the weather is mild, making it a pleasure to walk through the city both during the day and at night.

Limited rainfall allows you to get out and enjoy the outdoor activities — without worrying about excess heat.

But keep in mind:

Everybody knows this is a great season — including hotels and airlines, which jack up their prices.

Around Easter time, Catholic pilgrims and large groups of very noisy schoolchildren from all around the world descend on Rome. Plan your museum visits carefully, and make reservations.

May 1 is Labor Day in Italy, and all workers in Rome have the day off. Everything shuts down, even public transportation.

July and August

Summertime is when most people take their vacations, and there are many upsides:

The weather is beautiful, and outdoor life — especially in the sweet evenings — is at its max.

You can get discount rates in most hotels.

There is little traffic because residents tend to escape to the seashore, especially on weekends.

On the other hand, it may also be the worst time to come to Rome:

Airfares are high.

You can expect long lines for major attractions.

Temperatures during the day often soar into the 90s, and Roman ruins turn into ovens.

Many shops and restaurants close during August.

September and October

Next to spring, fall is a wonderful time to travel to Italy:

The weather is still fairly mild and pleasant.

With school back in session, crowds are relatively sparse.

On the other hand:

Hotel prices are high.

You have to watch for the rain, which typically starts falling in October.

November through March

More and more vacationers are reaping the benefits of traveling to Italy in the winter; if you can put up with rain and occasional cold spells, this is an excellent time for traveling to Rome:

The relatively mild weather keeps the city pleasant for touring. Rain is at its heaviest in November and December but is usually manageable.

There are fewer crowds at the prime attractions, and you often receive better and more attentive service.

Except for the Christmas–New Year's period, airfares and hotel rates are at their lowest.

On a rainy day in November, you might find the Pantheon almost empty.

But keep in mind:

Although average temperatures are mild, it can get quite chilly. Depending on how resistant you are to colder temperatures, you may not be able to enjoy some outdoor attractions.

Traffic is at its worst because most people take their cars to go to work and shopping when it gets nippy; correspondingly, air- and noise-pollution levels rise.
