Santorini in May is a great place to visit, but you should know that it’s not yet 100% summer and high season, so here is everything you need to know.
If you are planning to visit Santorini island in Greece in May, you should know that the weather will be great and it is possible to swim in the sea. The weather is usually anything between 15-30 degrees Celsius, and it is almost always sunny with clear blue skies.
BEST HOTEL IN SANTORINI ΜΑΥ:San Antonio
BUT ALSO CHECK:
May is considered the month where the high season pretty much starts, but it is still a relatively quiet month for the island compared to the super busy July, August, and September.
The island won’t feel crowded at all, and most of the businesses consider this month a “trial period” where they get organized for the upcoming tourism storm of the summer. However, this doesn’t mean that they won’t be operating normally. May is just the beginning of the “season”, as we call it in Greece.
Let’s put it this way: if August is 120% busy for Santorini, then May is about 50% busy.

May in Santorini is pretty hot and dry. The temperature can be anything between 15-30 degrees Celsius (and towards the end of the month, even more than 30 degrees Celsius!). It is usually sunny, but you may get cloudy and rainy days in the first half of the month.
May is an unpredictable month weather-wise in Greece, but it’s usually sunny, and it will feel nice and warm without being annoyingly hot.
During the day, you will be wandering the streets of Fira and Oia or the beaches of Kamari and Perissa with t-shirts and shorts in May, but you will need a light jacket in the evening and at night.
If it’s sunny (and towards the end of the month), it may even feel super hot! ????
May in Greece is considered spring and not summer, but it will mostly feel like the average north/central European summer, and even better.
It won’t feel at all like a Western European May with cloudy skies, rain, and extremely unpredictable weather. This is the Mediterranean!
May is the beginning of the high season (or should season, as some people call it), and your options are not limited. You may even get much better deals in hotels and restaurants.
In May, you are definitely avoiding the massive tourist crowds of July and August, which means more available hotel rooms to choose from.
Bear also in mind that 90% of the Greeks go on holidays in July or August, which makes things even worse.
It’s very rare for a Greek to go on holidays in May (the Greeks want the weather to be super hot, i.e., more than 35 degrees, to feel the need to go for holidays…never understood why though, but it’s a fact ????…)
So there is one less tourist crowd to compete with when you are searching for that nice table with the view at one of the best restaurants on the island or that nice sunbed at Perissa Beach.

However, because of how popular Santorini has become in the last few years, May might also feel a bit busy and crowded towards the end of the month (but again, that doesn’t necessarily mean that you won’t have a great time).
May is probably one of the best motnhs to visit the island, because the weather is still great but you will be avoiding the crowds and the high prices in hotels an restaurants which are following the high demand of the summer months.
Swimsuits, bikinis, monokinis, Borat-kinis, speedos, Hawaiian flowery shirts, normal t-shirts, shorts, every single summer dress you first saw on Instagram and then bought online, sandals, flip-flops, some hiking shoes (yes, you are going to do some hiking in Santorini, sitting on the pool all day with a cocktail is not good for your health ???? ) and so on…
You need all the summer clothes you can find, BUT you need to take some jackets and slightly warmer clothes for the less warm nights…
May is spring in Santorini but it will feel like summer for most people…!
Early May is a great time to visit Santorini because you will be avoiding the summer crowd while you will still be able to swim in the sea, and all businesses will be open on the island.
The seawater won’t be very warm because of the previous winter months, but that doesn’t mean that you will be prohibited from swimming and enjoying the amazing beach life and the awesome beach clubs in Santorini.
The black beaches of Perissa, Perivolos, and Kamari are amazing in May.

You can swim in Santorini in May, but the seawater might be less warm than it is in July or August. Or beach businesses, shops, bars, restaurants, tavernas, beach clubs, and hotels at the famous seaside towns of Kamari, Perissa, and Perivolos will be open and ready to welcome you.
May doesn’t feel like a hot season in Santorini, and that’s a very good thing!
July and August in Santorini are busy (like…crazy busy…!) and you can feel that everywhere: on the busy streets of Fira, during sunset time in Oia, at the beach bars of Perissa and Perivolos (where it might be super difficult to find a sunbed to lay down) and on the exhausted waiters and housekeepers of the island.
You can do everything you’d do during June, July, August, September, or October, as all businesses, tour operators, and hotels will be open as usual.
For May, here are the companies with direct flights to Santorini usually (these change every year, so please double-check before booking anything):
(Unfortunately, there are no direct flights from outside Europe to Santorini…you have to get off at Athens and then take another plane or ferry to Santorini if you are coming from the US)

Santorini in May is a great month to visit the island. Don’t get me wrong, you will have a great time in Santorini whenever you choose to go, but I strongly believe that May, June, and early October are some of the best months to visit the island.
You will be avoiding the crowds, you will enjoy the amazing landscape with fewer people around, you will avoid most of the massive and super annoying cruise ships, and you may even get better deals on hotels and tours.
The weather in Santorini in May is mostly hot and dry, with temperatures ranging between 15-30 degrees Celsius (59-86 Fahrenheit). It is usually sunny, though there may be a few cloudy or rainy days in the first half of the month. You can wear summer clothes during the day, but a light jacket is recommended for the evenings.
Yes, you can swim in Santorini in May. The seawater will not be as warm as it is in July or August because it is still warming up from the winter, but it is comfortable enough for swimming. All the beach bars and clubs in Perissa, Perivolos, and Kamari are fully open.
May is the beginning of the shoulder season in Santorini, so it is not overly busy. While all businesses, hotels, and restaurants are 100% open, the island only sees about half the tourist volume compared to the peak months of July and August. It is a great time to avoid massive crowds and get better hotel deals.
Yes, early May is a fantastic time to visit Santorini. You will enjoy sunny, warm weather and fully operational restaurants and tours, while avoiding the heavy summer crowds. It is considered one of the best times of the year to visit the island.
You should pack summer clothing like swimsuits, t-shirts, shorts, and sandals for the daytime. However, because May evenings can still be chilly, you should also pack a light jacket or sweater, as well as comfortable walking or hiking shoes for exploring the caldera paths.

Athens vs Santorini comes down to city history versus island scenery. Here’s how they compare on attractions, beaches, nightlife, food, cost, transport, and who should visit each.
Stand in Fira at noon. Count the cruise ships in the caldera below — usually four to seven on a high-season Tuesday. Listen, and you’ll hear four languages on every step of the cable car queue. Twenty minutes inland, in a Pyrgos church courtyard at the same hour, the only sound is a cat stretching […]

Thank you for a great article. We will be in santorini may 27-June 1 and we are reserved at Vedema
Now I am wondering if that’s a good choice in May or should I change to hotel in Oia or Fira
The reason we picked Vedema is because its quieter but if May is not as busy is a Vedema still a good choice?
hi there,
I think Vedema is not a bad option in any season.
Actually, at the time you are visiting (end of May – early June) the whole island is much livlier and you have nothing to worry about!
Actually May in Santorini is still high season and all shopes, restaurants and hotels are fully operational and open.
We are coming to Kamari at the beginning of May and I’m so worried about the weather! We hoped for some pool/beach time between exploring, and love sitting outside a Greek Taverna in the evening. Will that be possible that early on in the season?
hi there,
Absolutely!
You don’t have to worry about the weather in May in Santorini.
Yes, you may get some rain but that’s pretty rare to be honest.
Obviously, it won’t be as hot as it is in July or August but for just sitting outside enjoying your meal or your drink the weather would be perfect.
You would need a jacket in the evenings though but the weather would feel very pleasant to most people.
All this obviously depends on what weather you are used to, to be honest.
Do you mind me asking where you are travelling from so I can give you an idea of what the weather in May in Santorini would feel like?
