Where is it hottest in Greece in May?

The Greek islands have been famously synonymous with summer, as they offer the ideal backdrop for all kinds of travelers, and their diversity guarantees that there is at least one island you will want to return to time and time again. And with mainland Greece, and especially Athens, enjoying the reputation of an all-year-round destination, more and more people wonder when is the best time to visit Greece.

Of course, more and more people now tend to avoid the peak months (mainly July and August) and opt for a late spring escape without the crowds or the high temperatures that are a staple of the Greek summer experience. And they are right to do so, as by the end of May, temperatures across Greece have risen significantly, often ranging from 18 to 27 °C (64 to 81 °F), and the Greek islands are preparing to transition from their glorious spring awakening to their mythical summer glory. Also, rainfall is minimal, and most days are bright and sunny.

And now that we have painted a pretty enticing picture of late spring by the sea, you are probably wondering which are the hottest Greek islands in May, because you want to skip the summer but not miss the refreshing dips in crystal-clear waters and the sun-drenched days that call for exploration and relaxation. Well, the following choices deserve a spot at the top of your list!

1. Crete

If you know a thing or two about Greece, then it comes as no surprise that we start with the biggest Greek island. Crete generally enjoys some of the highest temperatures in May, with daily highs often around 22-25 °C (72-77 °F). Sea temperatures around the island average about 19-20 °C (66-68 °F), which is a bit cool but still allows for days spent on the beach, especially by late May when it gets even more comfortable.

Why visit Crete in May

If we started listing all the reasons why Crete is perfect in May (and throughout the year also), we would need a dedicated article. So, we will try to keep it short by saying that Crete offers the warmest overall island experience in May, giving you the opportunity to visit striking beaches like Elafonissi, Balos, and Vai without having to compete with hordes of people for your place in the sun, explore archaelogical marvels such as Knossos at your leisure, go hiking to one of the island’s many gorges, and always find a seat at the tavernas, where Cretan cuisine will leave you full and speechless with its unique flavours.

You can easily reach Crete from Athens, with many daily ferry crossings departing from the port of Piraeus. Check out all latest Crete ferry schedules and plan your trip hassle-free.

2. Rhodes

Rhodes, the biggest and most popular island in the Dodecanese, regularly records some of the highest average sunshine hours in Greece, with daytime temperatures often in the 23-26 °C (73-79 °F) range in May. The sea around Rhodes also warms up a little more quickly than on other islands, with average sea temperatures around 20 °C (68 °F).

Why visit Rhodes in May

Think wide beaches, charming seaside towns, lots of entertainment options, the chance to see the medieval Old Town without squeezing through countless other travellers who had the same idea, and this is what you can expect from visiting Rhodes in May. Plus, you can schedule a day trip from Rhodes to nearby islands, such as the little gems of Chalki and Symi, or hop to nearby Turkey to explore both sides of the Aegean Sea in a day.

Ferries to Rhodes depart daily from the port of Piraeus in Athens. Explore up-to-date Rhodes ferry schedules on Ferryhopper.

3. Kos

Another Dodecanese sunny haven, Kos sits in the southeastern Aegean and typically offers temperatures in the low- to mid-20s °C (70s °F) in May. Sea temperatures are similar, hovering around 19-21 °C (66-70 °F), plenty warm enough for a dip.

Why visit Kos in May

Kos is a favourite for summer, when vacationers from all over the world flock to the island for its sandy beaches and calm coves, historical sites like the Asclepeion of Kos, cycling routes, bike and hiking trails, and its overall vibrant atmosphere. Now picture all of the above without the extreme heat and the big crowds, and you can see why it is a good idea to visit Kos in May.

4. Santorini

And now, time for probably the most iconic Greek island, the mighty Santorini! We are happy to report that this volcanic wonder is warm in May, often reaching 20-24 °C (68-75 °F) during the day. Meanwhile, the sea around the island tends to be cooler than Rhodes or Kos but still within the typical 18-20 °C (64–68 °F) range.

Why visit Santorini in May

Santorini is a dream destination for countless travellers, and it is nothing short of dreamy in May. Some might argue that Santorini in late spring is even better than in summer, as you can take in the famous views (and its Instagram-worthy shots) without having to push through the masses for the best spot, explore its hiking trails and otherworldly landscapes without the blazing summer sun beating down on you, and also enjoy lower prices on the island’s hotels and rental rooms which are open for early season travel.
