May is when Greece waves goodbye to spring and prepares for summer and the hordes of tourists it brings.

That means you’re in for pleasant weather where the sun is out, but it isn’t scorching enough to require a whole day spent by the beach — not that anyone would judge you.

Expect the Greece temperature in May to average maximum temperature of 73°F (23°C), with around 10.5mm of rain and nearly 12 hours of sunshine.

The beginning of May is a little cooler, and the heat ramps up towards the end of the month. The country has a Mediterranean climate, but there are also differing climates in different parts of the country.

The Greek islands in the north are cooler but still offer balmy conditions you can take on without a jacket.

Being the shoulder season, there are also complimentary positives that make visiting Greece in May excellent, including:

  • Fewer crowds than in summer - Everyone loves the summer conditions in Greece, but in return, you get a crowded destination.
  • In May, you can get the best of both worlds - incredible temperatures and avoiding the crowds. Can you think of a much better one? We certainly can’t.
  • Lower costs - May is right by the end of the Greek shoulder tourist season, so your wallet is guaranteed to love it as much as you do.

Santorini in May is magical; it may just be the best time to visit Santorini to avoid the scrothing hit and overwhelming crowds of the summer months.

Can anything top the clear blue skies and turqoise hues of the Aegean Sea shining in contrast to the whitewashed towns when the sun sets? Probably, but you’ll likely have to jump into an abyss of fictional fantasy books to find it.

The beautiful Greek island experiences an average temperature ranging from an average low of 58°F to an average high temperature of 77°F (14°C to 25°C), 12 hours of sunshine, and just three rainy days.

This is perfect for enjoying a tour of Santorini highlights, grabbing Greek food from the street stalls, and everything in-between.

After a day of exploring, take our travel advice and take a dip in the clear waters of Perivolos Beach or spend the day soaking up the sun at Red Beach, one of the best Santorini beaches.

You can also venture inland on hikes to some of the highest spots in Santorini, like Prophet Elias, for a scenic vista. If you and your legs have no time for all that walking, then just take a leisurely stroll to Oia for another picturesque view.

Balmy temperatures? Check. Long and sunny days? Double check. A beautiful coastline with golden-sand beaches? Stop with the rhetorical questions already; Crete basically has everything you’d ask a genie for, including the best weather for exploring it on foot!

You can expect temperatures between 59°F to 75°F (15°C to 24°C), 11mm of rainfall, minimal cloud cover, and eight hours of sunshine. This sets the stage for the plethora of things to do in Crete, including a private Heraklion food tour that leaves no part of Crete gastronomy hidden.

Outside, you can take on a myriad of outdoor activities, such as scuba diving, snorkeling, and hiking. The Greece weather may bring a light drizzle from time-to-time.

When it rains, you can tuck away inside the Heraklion Archaeological Museum or discover the plethora of archaeological sites. Think Minoan palaces, tombs, and frescoes extant from Ancient Greek culture.

What’s the first thing that comes to mind when you hear ‘Mykonos’? The beaches, right? Fantastic, because May is perfect for enjoying a dip in the island’s incredible waters with temperatures between 57°F and 73°F (14°C and 23°C) and 12 hours of sunshine.

Stroll through The Little Venice district for a romantic view of the sunset, or visit the Archaeological Museum to delve into ancient Greek culture.

And if you want to dive into the waters of Mykonos, don't think twice, as the average water temperature is mild enough for even the less adventurous swimmers.

Trade in the tradition of traveling by car for a quirky, painted scooter to get around. It’ll be some of the most fun you have while on a shopping spree, from chic boutiques to traditional mom-and-pop shops on Matogianni Street.

Don’t forget to get a taste of Mykonos cuisine from places like Local Mykonos and Sakis. You don’t have to forget about the island’s gastronomical excellence when you leave; take a piece of it with you at this Mykonos traditional cooking class.

Paxos is one of the more unknown Greek islands, but nobody can hide the isle’s mostly fantastic weather.

It features temperatures ranging from 55°F to 75°F (13°C to 24°C) and nine hours of sunshine.

Unfortunately, you’ll be in for eight days of rain (which is the average rainfall weathercast), but a little rain is a small price to pay for the tranquility found here. At least you won't be afraid of an average snowfall level, as there is none!

In Paxos, the Mediterranean Sea sparkles beneath the warm sun, providing a calming presence as the gentle breeze floats through the tree leaves. Wildflowers line pathways leading to white-sand beaches and secret bays perfect for afternoon picnics.

Everywhere you look, there are vibrant colors delivered by nature's brushstrokes. You can stroll the quaint streets of picturesque villas that provide ideal spots to watch life unfold.
