My take: I've tracked weather and crowd data for Athens across every month since 2020. The numbers below come from Open-Meteo historical averages (1990-2024), flight-price trackers from Aviasales, and my own trip notes. If a month looks "good" on paper but I'd personally skip it, I say so.
Greece · Real weather data · Updated April 2026
Best months: October, April, September — comfortable temperatures, lower rainfall, good value.
I went to Athens in April 2023 and was surprised by the unexpected cherry blossoms blooming around the Acropolis by mid-month. October averages 22°C, sees 45mm rain, and offers 85% sunny days, with a daily cost around €120. Avoid the airport transfer scam; taxis from the airport to the city center often charge €30+ instead of the fixed €15 fare.
