The Athens heat in July and August

On extreme-heat days the Culture Ministry closes the Acropolis and other open archaeological sites during the hottest hours, typically 12:00 to 17:00, and outdoor work is restricted; this happened repeatedly through 2024 and 2025, with July 2025 seeing 43°C and four consecutive days of midday closure. There is no published temperature threshold — the decision is made day by day and announced that morning, so a timed ticket for an afternoon slot can be voided at short notice. Plan the Acropolis, Ancient Agora, Kerameikos and Sounion for the first slot after opening or the last two hours before closing.
