Climate overview
Temperature
Monthly mean temperatures reach their highest point in July at 26.2 °C, while the lowest monthly mean is in January at 7.5 °C. These figures describe each month’s average, not daytime high temperatures, so they do not show the full range visitors may experience from day to day. Across the calendar months, the unweighted mean of monthly mean temperatures is 16.3 °C; it summarizes the monthly averages rather than weighting them by the number of days in each month.
Rain
Mean daily rainfall is highest in November at 5.20 mm/day and lowest in July at 0.70 mm/day. These are average daily amounts, not monthly totals, and they cannot indicate how often rain falls or guarantee conditions on a particular day. The unweighted mean of the monthly mean daily rainfall figures is 2.47 mm/day. It provides a broad summary, while the contrasting monthly values show why that summary should not be treated as a prediction for every part of the year.
Sunshine
Mean daily sunshine duration is greatest in July at 13.31 hours/day and lowest in November at 6.47 hours/day. These averages describe sunshine duration, not day length, and do not promise the same amount of sun on an individual day.
Best Travel Time Guide for Rome, Italy: Ideal Seasons and Weather Insights
For visitors prioritising lower average rainfall, July is a conditional option, with mean daily rainfall of 0.70 mm/day. That average does not guarantee dry days or show rain frequency, so keep plans flexible and bring suitable rain protection if needed. If you are visiting in November, when mean daily rainfall reaches 5.20 mm/day, packing a compact rain layer is a prudent way to prepare without assuming rain will fall every day.
Visitors who prefer cooler monthly averages may consider January, the month with the lowest monthly mean temperature at 7.5 °C. It is a comparison of monthly averages, not a guarantee of cool conditions throughout the day, so check forecasts close to travel and bring adaptable layers. For outdoor sightseeing planned around sunshine duration, July has the highest mean daily sunshine at 13.31 hours/day, while November has the lowest at 6.47 hours/day. These figures can inform broad planning, but sunshine duration is not day length and does not ensure clear weather on a chosen date.
