Best time to visit Athens: month-by-month weather (2026)

The strongest months for visiting Athens are May, June, September, and October, based on the highest visit scores in the data. These months combine warm daytime highs, generally between the low 20s and low 30s Celsius, with long sunshine hours ranging from about 9.8 to 13.7 hours a day, and relatively modest rainfall compared with the winter months.

The trade-off is that May through October is also the peak season, meaning larger crowds and higher demand during these same well-rated months. Midsummer brings the most intense heat, with July averaging a high of 35.6C, while November and December bring the heaviest rain, with December averaging 103mm, making the shoulder months a compromise between comfortable weather and manageable crowds.
