Greece has an amazing and well-deserved reputation for being one of the sunniest countries on the planet — little wonder why so many people holiday here. But when is the best time to visit Greece based on weather and tourism seasons? And what about the Greek islands specifically?
In this guide, the SIMOVO team breaks down when they prefer to spend time in Greece the most, and when the best weather and crowd levels will be for your preferred type of holiday.
Greece weather and travel seasons explained
It's easy to assume that summer in the northern hemisphere is always going to be the best time to visit Greece. It's not an incorrect assumption — but keep in mind that Greece and its islands have a Mediterranean climate, which means the sun shines here most of the year, and when summer hits, it's extremely hot.
Travel experts and the SIMOVO team actually advise that the best time to visit Greece is somewhere between mid-spring and mid-autumn. It's during this time when you're least likely to experience rainfall, and you benefit from smaller crowds and milder weather if you choose April or October over June or July.
The best time to visit will also depend on what you'd like to do here. If you're keen to go hiking across the mountains, the milder months are ideal — though summer is also a great time to escape the lowland heat by heading to the peaks.
[tip title="Greece's tourist season runs from Easter to just before Halloween"]Travel outside of this window and crowds will be smaller — but some attractions may be closed and the weather less reliably warm. The shoulder seasons on either side (April to May and September to October) offer the best balance of open attractions, good weather, and manageable tourist numbers.[/tip]Greece by season

Greece in spring
Greece is warm and pleasant in spring, with April tending to bring the best temperatures and the least chance of rainfall. It gets quite busy during this period, but you have the benefit of a nice breeze and sunshine that isn't stifling — making it one of the most comfortable and enjoyable seasons to explore the country.
Greece in summer
Greece is absolutely spectacular in summer, but the temperatures absolutely explode — and there's minimal rainfall. Even avid sun seekers may feel more than a bit uncomfortable during the hottest parts of the day. It is, however, a fantastic time for diving and snorkelling, as the sea is warm and inviting.
[warning]Greek summers regularly exceed 35°C and can spike significantly higher — particularly inland and on the smaller islands. Heat exhaustion can develop quickly during extended outdoor sightseeing. Always carry water, wear high-SPF sunscreen, avoid prolonged exposure during midday hours, and take regular breaks in shade or air conditioning. This applies equally to beach days and city exploration.[/warning]Greece in fall/autumn
Greece's autumn days are surprisingly long and sunny — the summer really does tend to go on forever here. The weather gradually gets milder, making adventuring around the various regions more comfortable. It's also a great time for swimming, as the sea water remains warm well into October before it starts cooling off significantly.
Greece in winter
Winter is the best time to beat the crowds in Greece. The south stays extremely mild, while the north gets quite chilly — and rainfall between December and February is more likely, so pack accordingly.
[warning]Many of Greece's most popular attractions, island ferry services, and beach resorts close over winter and do not reopen until Easter or later. If you visit between November and February, be prepared for a significantly reduced experience — limited island hopping, fewer restaurants open, and key archaeological sites and museums potentially operating on reduced hours. Always check opening dates before planning a winter trip.[/warning]Best months to visit Greece
Generally speaking, April and October are the best months to visit Greece — the sweet spot of mild weather and lower tourism. These shoulder months tend to offer the best chance of affordable flights, accommodation, and day rates for anyone looking to experience the best of Europe's sun and sea without the peak-season prices.
[tip title="July and August are spectacular — if you can handle the heat and the crowds"]Summer maximalists will argue that July and August are the best months to visit Greece — and honestly, the islands, mainland, and surrounding waters really do shine at this time. It just happens to get quite overwhelming for some visitors. If you've never been to Greece before and prefer a calmer, more comfortable introduction, April and October are the stronger choice.[/tip]Best time to visit Greek islands
The best time to visit the Greek islands falls somewhere around late spring and early autumn. Island sea breezes make the heat more manageable, and tourist numbers tend to be slightly lower than on the mainland even in peak season.
[tip title="Shoulder season for peace, July and August for nightlife"]If you want the most laid-back island experience, travel in late May, June, or September. If you're after the best nightlife, beach parties, and buzzing atmosphere, July and August are when the islands really come alive. The ideal approach is to visit a few times across different seasons and get a feel for when the islands work best for you personally.[/tip]Travel tips for visiting Greece
Here are some top tips to remember, regardless of when you visit Greece.
[tip title="Always carry cash — many vendors only accept cash"]You're going to need Euros throughout Greece. Cards and mobile payments are accepted at larger establishments, but plenty of stalls, vendors, and smaller tavernas — particularly on the islands — only accept cash. Always carry paper money so you're never caught short when you want to eat, shop, or pay for transport.[/tip] [tip title="Expect dinner to start late — usually after 9pm"]If you're keen to sample the best Greek food, keep in mind that restaurants in Greece tend to stay open late because locals typically eat dinner after 9pm. You don't have to change your own routine completely — just keep an open mind and embrace the pace if you want the most authentic dining experience.[/tip] [tip title="English is widely spoken but a few Greek phrases go a long way"]English is broadly spoken around the country and the islands, mainly thanks to tourism. Greek is of course the main language, and learning even a few basic phrases before you travel is always appreciated by locals and makes the experience feel more genuine.[/tip] [esim flag="🇬🇷" label="Greece" data="10GB · 30 days" price="£9" href="/products/greece" benefits="Instant QR setup · Reliable 4G/5G · No contract"]Stay connected across Greece and the islands — no roaming charges[/esim] [faq] [q]When is the best time to visit Greece?[/q] [a]April and October are the two best months to visit Greece — mild temperatures, low rainfall, manageable tourist numbers, and the best value for flights and accommodation.
