What’s the weather like in Greece in May?

Greece is a country with varied geography. It’s mountainous, borders three seas and has almost 14,000km of coastline. There’s different weather around the country, although the most popular holiday destinations have a typical Mediterranean climate. If you’re going in May you can look forward to rising temperatures, which are nearly at their summer peak, and not much rain after the wetter winter. Large parts of Greece are mountainous or hilly, and the northern Pindus Mountains have quite a big impact on the weather. You’ll see less rain in the east than in the west but will be driest in the south where Greece’s famous islands are.


The average high in southern Athens is 25ºC in May, which cools to 14ºC at night, so you should bring a warm jumper for the evenings. The sea temperature is 19ºC, while humidity’s low. There’s 23mm of rain over four days, and you can expect 14 hours of daylight with ten hours of sunshine each day. Make sure you pack plenty of sun cream as UV levels will be very high. The sun goes down at around 8.30pm through much of the month.
