What you gain in September

  • 29°C and 9 hours of sun — optimal for the Acropolis, the Ancient Agora, and the National Gardens without any risk of heat exhaustion
  • Cruise traffic drops noticeably after the first week; the Plaka recovers something of its neighbourhood character from mid-month
  • Athens Epidaurus Festival final performances: late September outdoor theatre in cooling evening air is genuinely one of the best experiences Greece offers

What you sacrifice

  • Prices lag behind the crowd reduction: September still carries June-level pricing in most hotels and restaurants
  • The first occasional autumn rains arrive in the final week — nothing severe, but outdoor plans need contingency
  • Acropolis pre-booking still essential; the site hasn't emptied enough to risk same-day entry
