Climate Chart of Athens, Greece

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

Climate overview

Temperature · Rain

Monthly mean temperatures range from January at 9.0 °C to July at 28.3 °C, marking the coolest and warmest monthly averages in the record. These are averages for each month, not daytime highs, so they do not describe the full range visitors may experience within a day. Rainfall follows a different calendar pattern: the lowest mean daily rainfall is in July at 0.23 mm/day, while the highest is in December at 2.55 mm/day. These figures are daily averages rather than monthly totals, and they do not indicate how often rain falls or guarantee dry or wet weather on a particular day.

Sunshine

Daily sunshine duration averages are highest in July at 13.07 hours/day and lowest in December at 6.81 hours/day. This can help frame expectations for daylight outdoor planning, but sunshine duration is not the same as day length and monthly averages cannot promise the conditions on an individual visit.

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

For visitors prioritising cooler monthly averages, January is the relevant choice in the record, with a mean temperature of 9.0 °C. Treat that as a monthly average rather than a forecast or a measure of daytime highs; flexible clothing can help accommodate day-to-day variation. If lower average rainfall is the priority, July has the lowest mean daily rainfall at 0.23 mm/day. It is a conditional option, not a guarantee of dry days or a measure of rain frequency; visitors should still be prepared for changing weather.

Rain preparation matters most for visitors considering December, when mean daily rainfall reaches its highest monthly average at 2.55 mm/day. A light rain layer or an adaptable plan may be useful, while remembering that the average does not predict whether rain will fall during a particular outing. For outdoor sightseeing with sunshine in mind, July records the highest mean daily sunshine duration at 13.07 hours/day; December records the lowest at 6.81 hours/day. These averages can inform daylight planning, but they do not establish day length or guarantee sunshine, so they should not be treated as a single overall ranking of when to visit.
