Rome Weather in October
Planning a trip to Rome in October? Here's what the weather is really like as autumn settles in — and one distinctive storm pattern worth knowing about.
October is a fantastic month to visit Rome. Highs start the month in the upper 70s°F and dip to the mid and upper 60s by month's end. Overnight lows start around 60 and drop into the 50s by the end of the month, so some cool mornings are possible, especially mid-to-late October. Rain picks up: 7–8 days on average, with about 4.5 inches spread across the month, making it the second-wettest month behind November.
Occasionally those rains come as intense storms that can cause flooding in the countryside and sometimes reach into the city. The reason is a specifically Italian weather pattern: Genoa lows. Cold air moving through the mountains interacts with warm Mediterranean air and creates low-pressure systems that can park over Italy and dump heavy rain. The extra lift in the mountains makes flooding a real risk in the countryside in October and November, and some of that rain can make it to Rome too. Not a reason to cancel — just a reason to keep an umbrella handy. Meteorologist Ian Schwartz breaks down what to expect.

What are Genoa lows?
A specifically Italian weather pattern.

They're common in October and November and can cause real flooding — especially in the countryside, but sometimes affecting the city too.
Is October a good time to visit Rome?
A fantastic month. Temperatures are comfortable, autumn light is beautiful, and crowds thin from summer peaks. The trade-off is more rain than the summer months and the occasional heavy storm from a Genoa low. Pack an umbrella and check the forecast — but don't let it change your plans.
