The Ideal Time to Explore Greece

Are you finally setting your sights on that dream getaway to Greece but unsure about the best time to go? Many travelers deem the warm, dry summer months of June, July, and August as the prime time for a visit. However, there’s much to enjoy beyond this peak season, which also attracts the largest crowds in this Mediterranean paradise.

During September and October, the beaches are less crowded, yet the weather remains pleasant enough for swimming. If your plans involve exploring ancient landmarks, consider visiting in spring or fall, as you can anticipate mostly sunny weather with milder temperatures.

Discover the optimal times to visit Greece, whether your plans include island hopping, exploring archaeological treasures, or dodging the crowds.

Optimal Time to Experience the Greek Islands

• Optimal months: April–June, September–October

The ideal timeframe for island hopping in Greece is from April to October. Although spring and fall may bring occasional rain, the weather is generally sunny and warm. The northern regions tend to be cooler, while southern areas experience higher temperatures. By June, the waters around Greece are warm enough for swimming and remain so until about mid-October.

July and August see peak prices, temperatures, and crowds, especially in popular island clusters like the Cyclades, Ionian, and Dodecanese. During these months, average temperatures typically stay in the mid-80s Fahrenheit but can often soar into the mid-90s, with a high likelihood of heatwaves.

As the summer season concludes at the end of August, the islands become noticeably quieter, making September and October ideal months to relax by the sea. Average temperatures range from the low 80s in September to the high 70s in October.

Ideal time to explore Greece for sightseeing

• Optimal months: April–May, September–November

Spring and fall offer exceptional opportunities for sightseeing. Wandering through ancient sites like Delphi, Epidaurus, and Olympia is far more enjoyable in spring, with temperatures averaging between 60 and 70 degrees. While you might encounter some rain and cooler weather—so layering may be necessary—a simple T-shirt is usually sufficient.

Exploring archaeological sites in early spring or late fall provides a more relaxed experience compared to the summer months, when large cruise ship tour groups crowd these attractions. You’ll find shorter ticket lines or none at all.

Optimal time to visit Greece for a crowd-free experience

• Ideal months: October–May

Summer marks the peak tourist season in Greece, so if you prefer to avoid the throngs, plan your visit accordingly. Even September now attracts a considerable number of visitors, especially those not restricted by school holidays.

By October, the beaches, towns, and tavernas of Naxos, Paros, and Kos are wonderfully tranquil. You can expect nearly perfect blue skies during a November stroll through the medieval old town of Rhodes. This month also offers some of the best deals on domestic flights and accommodations.

As winter arrives, consider exploring the northwestern mountainous regions of Greece. Aside from the Christmas and New Year’s holidays, the Epirus area sees relatively few travelers—where cozy fireplaces and warm hospitality await guests at charming stone-built boutique hotels. Many of the most beautiful are nestled in the traditional villages of the UNESCO World Heritage-listed Zagori, home to the stunning Vikos Gorge.

Winter presents the perfect opportunity to experience Santorini’s enchanting beauty without the interruption of selfie enthusiasts. Expect average temperatures around 55 degrees, with a limited selection of hotels catering to a diverse array of off-season visitors.

Ideal time to visit Athens

• Optimal months: October–May

Instead of simply adding a short stay in Athens at the beginning or end of your busy summer island adventure, consider dedicating a full week to thoroughly explore the intricacies of this vibrant city.

The best time to visit the Greek capital is during the fall, winter, or spring when Athens truly shines, and notably when locals are present. This allows you to gain a richer understanding of life in this lively metropolis where ancient history blends seamlessly with modern culture.

Don’t be fooled—winter can be quite chilly. However, if you're open to the possibility of a rainy day or two, this is the perfect time to capture the Acropolis and its monuments bathed in golden afternoon light without the tourist crowds. You can explore gems like the National Archaeological Museum and the Museum of Islamic Art with minimal visitors. Plus, food enthusiasts can savor Athens’s growing array of Michelin-starred restaurants along with beloved family-run mezze spots that never lose their charm.
