The climate of Rome

Rome, much like the rest of Italy, is the epitome of the Mediterranean climate, falling under the Köppen climate classification of Csa. The city sits on the western side of central Italy, confined by the Apennine Mountains and the Tyrrhenian Sea. The Mediterranean climate gives Rome hot summers and mild winters, with noticeable variations in temperature and rainfall throughout the year.

A distinct characteristic of Rome's climate is the oscillation between monthly temperatures. Based on available data, temperatures can fluctuate from a brisk 3.1°C (37.6°F) in January to a blistering 30.6°C (87.1°F) in August. Rainfall also follows a pattern throughout the year, peaking at 115mm (4.53") in November and shrinking to as low as 19mm (0.75") in July. Observing the daylight hours, Rome enjoys a maximum of 15.2 hours in June and a minimum of 9.2 hours in December.

One unique aspect about Rome's weather conditions is the frequency of sunshine hours in the summer. Extended periods of sunlight reaching up to 10.7 hours are recorded in July. Concurrently, there is a surge in the UV index in July, reaching 9. Rainfall days exhibit a different trend - mostly concentrated in the late autumn and early winter months, specifically November (9.7 days) and December (8 days).

The best time to visit Rome

Determining the "best" time to experience Rome largely depends on an individual's preferences.

Therefore, the period from late September through to October is highly recommended.
