Climate Chart of Rethymno, Greece

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

Monthly mean temperatures range from a high of 26.6 °C in August to a low of 13.0 °C in January. These figures describe month-level averages, not daytime highs or the temperatures visitors will experience on every day. The unweighted mean across the monthly means is 19.4 °C, a broad summary rather than a day-weighted annual average.

Rain

Mean daily rainfall is lowest in July, at 0.25 mm/day, and highest in December, at 4.61 mm/day. These are daily averages for the respective months, not monthly rainfall totals, and the lower figure does not mean every day is dry or reveal how often rain occurs. The unweighted mean of the monthly daily-rainfall means is 2.27 mm/day.

Sunshine

Average daily sunshine reaches its highest level in July, at 12.99 hours/day, and its lowest in December, at 7.41 hours/day. These duration averages can help with broad outdoor-planning expectations, but sunshine hours are not the same as daylight length and do not guarantee clear skies on a given day. The unweighted mean across the monthly figures is 10.28 hours/day.

Snow

The highest monthly mean daily snowfall is recorded in January, at 1.16 mm/day; the unweighted mean of the monthly daily-snowfall means is 0.17 mm/day. These averages do not establish how many days have snow, snow depth, persistent cover, or whether conditions support skiing.

Best Travel Time Guide for Rethymno, Greece: Ideal Seasons and Weather Insights

For visitors prioritising lower average rainfall, July is the conditional option indicated by the lowest mean daily rainfall, 0.25 mm/day. This average cannot guarantee dry days or describe rain frequency, so keep plans flexible and check forecasts close to travel. If cooler monthly averages are the priority, the lowest monthly mean temperature occurs in January at 13.0 °C. It is a month-level mean, not a forecast of daytime conditions; pack for changing daily weather rather than relying on the average alone.

Rain preparation is especially relevant around December, when mean daily rainfall is highest at 4.61 mm/day. This does not mean rain every day, but a light waterproof layer and flexible outdoor plans are sensible precautions. For daylight outdoor planning, July has the highest average daily sunshine at 12.99 hours/day, while December has the lowest at 7.41 hours/day; sunshine duration is not day length and cannot ensure clear weather.
