Peloponnese travel guide
The peninsula works all year, but each season gives a different trip. Here is what to expect, and when we would go.
The short answer
For warm days, a swimmable sea and fewer people, choose May, June, September or October. July and August are the hottest and busiest. Winter is mild on the coast and quiet.
What suits you depends on what you want to do. Swimmers need late May to October. Walkers prefer spring and autumn. Climbers come from autumn to spring.

Season by season
March to May
Wildflowers, green hills and good walking weather. The sea is still cool, and some seasonal places open late.
June
Long days, warm sea and lively villages before the peak.
July and August
The hottest and busiest months. Go for the sea, walk early and plan a long midday break. Book ahead.
September and October
A warm sea, softer light and fewer visitors. Many people’s favourite months.
November to February
Mild on the coast and quiet. Some places close. Snow can fall on Parnon, and climbers fill the east coast.
Our tip
If you can choose, come in September. The sea is at its warmest and the crowds have left.
Special moments
Orthodox Easter is an important time in Greece, with village traditions in many places. Leonidio is known for its Easter night of lit balloons, so check the date each year.
Summer festivals, including a local aubergine festival near Leonidio, are usually held in July and August. Check dates each year.
