Greece travel guide
The best time to visit Greece is May to June or September to October, when the weather is warm, the sea is inviting and the islands are calmer than in peak summer. July and August bring the hottest weather and the liveliest atmosphere, perfect for families travelling in the school holidays. Winter is mild and quiet, with many island hotels closed until spring, while Athens and Crete welcome visitors all year round.

Figures are typical averages and vary by island and region. Crete and Rhodes are usually a little warmer, and northern Greece a little cooler.
June to September offers the most reliable beach weather. Choose September for the warmest sea and a calmer atmosphere once the school holidays end.
July and August fit the school holidays and every resort facility is open. Book early, as family suites and interconnecting rooms are in high demand. The May half-term and October half-term are excellent alternatives with milder heat.
April, May and October are ideal for exploring ancient sites such as the Acropolis and Knossos without the midday heat of high summer.
Late May, June and September bring romantic warm evenings and easier restaurant reservations in Santorini and Mykonos.
Early and late season, in May and October, typically offer the best value on luxury hotels, with lower prices than in peak summer.
Tip: Greek Orthodox Easter is the country’s biggest festival and usually falls on a different date to UK Easter. It’s a wonderful time to visit, but book early.
