Climate overview

Temperature

The monthly mean temperature is lowest in January at 9.0 °C, and reaches its highest point in August at 25.9 °C. These are averages for each month, not daytime maximum temperatures, so they do not show the range visitors might experience within a day. The unweighted mean of the monthly means is 16.8 °C; it summarizes the calendar-month averages without weighting them by the number of days in each month.

Rain

Mean daily rainfall is lowest in July at 0.48 mm/day, while the highest monthly mean occurs in November at 7.04 mm/day. The values are daily averages, not monthly totals, and do not indicate how often rain falls or whether a particular day will be wet. Across the calendar-month means, the unweighted mean is 2.92 mm/day, a broad summary rather than a day-weighted annual figure.

Sunshine

Daily sunshine duration has its highest monthly mean in July at 13.47 hours/day and its lowest in December at 6.63 hours/day. These averages can help with broad outdoor planning, but sunshine duration is not the same as day length and does not guarantee clear conditions on a particular day. The unweighted mean across the monthly averages is 9.77 hours/day.

Snow

The highest monthly mean daily snowfall is recorded in February at 0.12 mm/day; the unweighted mean of the monthly means is 0.02 mm/day. These daily averages do not establish how many days have snowfall, how deep any snow becomes, or whether snow cover or skiing conditions occur.

Best Travel Time Guide for Naples, Italy: Ideal Seasons and Weather Insights

For visitors prioritising lower average rainfall, July is the criterion-based option, with mean daily rainfall of 0.48 mm/day. This does not guarantee dry days or say how frequently rain occurs, so flexible plans and a light rain layer remain sensible. If visiting in the month with the highest mean daily rainfall, November at 7.04 mm/day, prepare for the possibility of wetter conditions without treating the average as a forecast. Visitors prioritising cooler monthly mean temperatures can look to January, when the mean is 9.0 °C; it is not a daytime high, so allow for conditions to vary during the day. For daylight outdoor planning, July has the highest mean daily sunshine duration at 13.47 hours/day, while December has the lowest at 6.63 hours/day. These measures describe average sunshine duration, not day length or guaranteed sunshine, and point to different criteria rather than one universal best time to visit.
