How Does Weather & Best Time Work in Greece?
Last verified: 2025-06 · Europe
1The Quick Answer
The best times to visit are April–June and September–October — warm, uncrowded, and with lower prices than peak summer.
2What You Need to Know
Greece has a Mediterranean climate with hot, dry summers and mild, wet winters. July and August are the peak tourist months: temperatures regularly exceed 35°C and popular islands like Mykonos and Santorini become very crowded and expensive. The meltemi — a strong northerly wind — can disrupt ferry services across the Aegean in August. April to June offers warm weather, blooming wildflowers, and significantly fewer crowds. September and October are excellent for beach holidays with warm sea temperatures and quieter resorts. Athens is comfortable year-round, even in winter.
3Practical Tips
Practical Tips
- 1Visit the Acropolis and other outdoor archaeological sites early in the morning (opening time) in July and August to beat the heat and crowds.
- 2September is arguably the best month for island-hopping: sea temperatures are at their warmest, crowds have thinned, and prices drop after August.
- 3Check ferry operating status during the meltemi season (August) before planning tight onward connections from Aegean islands.
Important Warning
The meltemi wind can cancel or significantly delay ferries across the Aegean in August — always book accommodation with flexible cancellation and allow buffer days near flights.
