Climate Chart of Santorini, Greece

Climate overview

Temperature

Monthly mean temperatures range from January at 12.4 °C to August at 25.9 °C. These are monthly averages, not daytime highs, and individual days may differ from the pattern they describe. Across the calendar months, the unweighted mean of the monthly temperature means is 18.8 °C. It offers a broad annual reference, but does not represent a day-weighted average or indicate the temperature expected on a particular visit.

Rain

Mean daily rainfall is highest in February, at 1.79 mm/day, and lowest in July, at 0.02 mm/day. The difference can help frame rain preparation, but these daily averages do not show how often rain falls or guarantee a dry day in the lower-average month. The unweighted mean of monthly mean daily rainfall is 0.76 mm/day. This is an average daily amount, not a monthly rainfall total, and it cannot by itself describe the timing or duration of individual rain events.

Sunshine

Mean daily sunshine reaches its highest level in June, at 13.20 hours/day, and its lowest in December, at 7.54 hours/day. These averages may help with outdoor scheduling, but sunshine duration is not the same as daylight length and does not promise clear skies on a given day. The unweighted mean of monthly mean daily sunshine is 10.50 hours/day, providing a broad reference across the year rather than a forecast for any particular date.

Snow

Recorded mean daily snowfall is highest in January, at 0.13 mm/day; the unweighted mean across monthly means is 0.01 mm/day. These small average amounts do not establish how many days have snow, snow depth, ground cover, or skiing conditions.
