WhatAWeatherClimate in Rome
Rome has a Mediterranean climate with continental influence due to its inland position. Summers are hot and dry, with average highs of 31 degrees Celsius, and winters are mild with average lows of 4 degrees.
Annual rainfall is around 800 mm, concentrated in autumn and winter. Mediterranean cut-off lows can deliver intense rain in a few days, with problems along the Tiber and low-lying areas.
The sirocco, a hot, dusty wind from North Africa, arrives several times a year and can spike temperatures and degrade air quality. The northerly tramontana brings cold, dry air in winter.
Best time to visit is spring (April-May) and autumn (September-October), avoiding the extreme July-August heat. Use the hourly forecast, UV index and air quality before planning the Colosseum, the Forums or Vatican City.
