Climate overview
Temperature
Monthly mean temperatures are lowest in January, at 11.5 °C, and reach their peak in August, at 26.9 °C. The 18.5 °C mean is an unweighted average of the monthly means, not a day-weighted annual average. These figures describe average temperatures for each month; they are not daytime highs and do not show the range visitors may encounter from day to day.
Rain
Mean daily rainfall is lowest in July, at 0.28 mm/day, while the highest monthly mean occurs in November, at 3.46 mm/day. The unweighted mean across monthly means is 1.99 mm/day. These are daily averages, not monthly rainfall totals: they do not establish how often rain falls or guarantee dry weather in the lower-rainfall month.
Sunshine
Mean daily sunshine reaches its highest level in July, at 13.32 hours/day, and its lowest in December, at 7.22 hours/day. The unweighted mean across monthly figures is 10.14 hours/day per day. These averages can help with planning outdoor time, but sunshine duration is not the same as day length and does not specify conditions on an individual day.
Snow
The highest monthly mean daily snowfall is recorded in January, at 0.60 mm/day; the unweighted mean across monthly figures is 0.08 mm/day. These small average amounts do not reveal the number of snowy days, snow depth or snow cover, so they cannot establish whether snow-related activities will be available.
Best Travel Time Guide for Sicily, Italy: Ideal Seasons and Weather Insights
For visitors prioritising cooler monthly averages, January is the relevant reference point, with a mean temperature of 11.5 °C; this is a monthly mean, not a daytime maximum or a forecast for a particular visit. Those seeking lower average daily rainfall can consider July, when the mean is 0.28 mm/day, while packing for possible showers remains sensible because the average does not quantify rain frequency or promise dry days. If outdoor sightseeing and sunshine duration are priorities, July has the highest mean daily sunshine at 13.32 hours/day; that figure indicates average sunshine hours, not day length. Rain preparation may be especially relevant in November, which has the highest mean daily rainfall at 3.46 mm/day. These criteria point to different planning considerations rather than establishing one universally best time to visit.
Snowfall averages are small, with the highest monthly mean daily amount in January at 0.60 mm/day. This cannot tell visitors how many snowy days to expect or whether snow will lie on the ground, so it is not a basis for assuming snow cover or suitable skiing conditions.
