About Athens

From April to June, Athens enjoys dry 18–25°C days with northerly meltemia breezes that keep the marble Acropolis bearable. Climb before 9am to dodge both heat and tour buses, then trace the Ancient Agora’s stone paths as light softens. By evening, Plaka’s narrow lanes fill with locals at outdoor tavernas serving grilled octopus. Late May sees low crowds and wildflowers on the slopes of Filopappou.
