When is the best time to go to Greece?

The peak tourist season in Greece corresponds to not only the summer season but also the time of school holidays. Most tourist sites see a large influx of vacationers, travelling from around the world. For this main reason, one should consider making their reservations well in advance in order to ensure a reasonable price with adequate accommodation. Especially if one desires to enjoy the sun and sea in peace. Otherwise, spring and fall are beautiful to visit Greece in all its authenticity.

Some Greek islands can even be visited all year round. During these off periods, one can benefit from the low level of tourists in order to privately discover the ancient ruins, relax on the Greek countryside and soak up the hospitality of the residents who live away from the modern world. If one is visiting Greece during the off season, take a moment to travel to Macedonia throughout the winter as this can be exciting: one can follow the footsteps of the great historical figures like Aristotle and Alexander the Great at a personal pace, while enjoying the peace and nature.

So, when is the best time to go to Greece? Here's some more information to help you in your decision:

  • In Greece, the weather is good everywhere in May, June, July, August and September

Climate and Weather in Greece

Throughout most of its territory, Greece has a Mediterranean climate which varies mainly with the differing altitudes and latitudes of the region. In general, we find mild, rainy winters and hot dry summers, like its neighbors, Albania, Bulgaria and Turkey. Less notable, seasons like the fall or the spring, although they are relatively pleasant, are generally short when compared to the summer or winter seasons. The climate in Greece is regularly softened and cooled by the wind on the coast, but the heat is quite common within the country.

The Mainland's Climate in Greece

The winter is in general rather mild and humid and the summers are hot and dry on the Greek mainland, it is not however uncommon for particularly cold temperatures in mountainous regions or in the capital, Athens. This approximates the harsh winters of Turkey, including Ankara as well, or as in Sofia, Bulgaria. In Athens and more generally inland, the heat is also sometimes extreme, causing it to be unbearable at times. On the coast however, the climate is similar to that of the Greek islands, thanks to the intervening North Winds which temper the summer heat. Note the possible appearance of “alcyoneus” days throughout January and February, which offer beautiful moments of sunshine in the middle of the winter blues.

The climate of the mainland in Greece also faces great temperature variations, depending on the location. Thus, summers are particularly hot in the Peloponnese and in the north, while the winters are long and cold. Despite such, Macedonia still faces very hot summers as well!

The Climate on the Greek Islands

Quite different from the mainland climate, the weather of the islands varies enormously depending on which part of the archipelago that one is located. Thus, the Ionian Islands face a lot of humidity and low wind exposure, creating the scorching summer temperatures while the Cyclades suffer from drought on a fairly regular basis when the summer arrives, the latter period lasting for six months in this part of the archipelago and rather popular with the tourists. There are times when the rain may indeed be entirely absent between the months of May and October. The summers are pretty cool though, thanks to a seasonal wind known as “Meltemi” that refreshes the whole of the atmosphere. Sporades and Dodecanese face themselves a climate similar to that of the Cyclades - with lesser important winds and a warmer summer.
