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
