Why is Athens warm in August?
Athens's August weather is dominated by the Azores High, a semi-permanent subtropical anticyclone that blocks Atlantic rain systems from reaching the Mediterranean. As a result, August delivers reliably sunny, dry conditions with temperatures averaging 33°C. The sea moderates extreme heat and keeps overnight lows around 22°C, making the city noticeably more comfortable than inland Mediterranean destinations. Climate data: Open-Meteo ERA5 (1991–2020).
