Athens has a Mediterranean climate with scorching summers and mild winters. The city bakes under the sun from June to September, making spring and autumn the ideal times for exploring the Acropolis, the Ancient Agora, and the hillside neighborhoods of Plaka and Anafiotika.
April and October are the sweet spots. In April, temperatures are comfortable (20C), wildflowers cover the hills around the Acropolis, and if your visit coincides with Greek Orthodox Easter, you'll witness one of Europe's most powerful religious celebrations — midnight church services, fireworks, and lamb roasting across the city. October offers similar temperatures with the bonus of warm sea swimming.
Summer visitors must be prepared for serious heat. July-August sees temperatures regularly above 33C, with heat waves pushing 40C+. The Acropolis has no shade and closes during extreme heat (above 43C). If you must visit in summer, go to archaeological sites at opening time, retreat to air-conditioned museums midday, and enjoy the Athenian Riviera's beaches (tram to Glyfada or Voula) in the afternoon.
July-August is genuinely hot (33-40C+). The Acropolis has no shade and can be brutal at midday. If visiting in summer, go to outdoor sites before 10 AM, use museums as midday refuge, and stay hydrated.
It moves each year — sometimes matching Western Easter, sometimes weeks later. Check the Greek Orthodox calendar. If your dates overlap, the midnight Resurrection service on Holy Saturday is extraordinary.
