Greece in August
The warmest sea and the fullest islands. 15 August is the busiest day of the Greek travel year — book every ferry.
August has the warmest water of the year — around 25–26°C in most places and close to 28°C off Rhodes — and the heaviest demand. Europe is on holiday and so is Greece: around the Dormition on 15 August, Greeks head to their home islands, ferries sell out and room prices peak.
It can still be a good trip, if you plan for it. Book boats and rooms well ahead, pick bigger islands that absorb crowds (Crete, Kefalonia, Naxos) or the Ionian side, and swim early and late. The meltemi blows hard in the Cyclades. For Romanians driving down, summer border queues can be long — check them live before you set off.

Where to go this month

Kefalonia is the largest Ionian island and the most grown-up: mountains and fir forest, cave lakes, pastel villages like Fiskardo and Assos, and cliff-backed beaches such as Myrtos. Rent a car, slow down and plan on a week.

Greece’s largest island is almost a country of its own: Minoan palaces at Knossos and Phaistos, Venetian harbours in Chania and Rethymno, gorges in the White Mountains and lagoon beaches like Balos and Elafonisi. Plan for distance, and for more than a week.

The largest of the Cyclades and the most self-sufficient: marble villages, mountain farms, Archaic temples and a west coast of long, shallow sandy beaches. Naxos suits families, walkers and anyone who wants the Aegean without Mykonos prices.

Skopelos is the slower, greener neighbour of Skiathos: a steep white harbour town, pine-framed pebble bays, plum orchards and the clifftop chapel from Mamma Mia!. No airport, so it rewards people who like the journey.

Three pine-covered peninsulas south of Thessaloniki: busy, sociable Kassandra, greener Sithonia with its turquoise coves, and the monastic republic of Mount Athos. Northern Greece’s beach playground, and an easy drive from Romania.

Paxos is a small, olive-covered island south of Corfu with no airport: three harbour villages, a cliff-lined west coast full of sea caves, and a short hop to Antipaxos and the turquoise water of Voutoumi.
