All is more tourists visiting Greek resorts off-season. There are many reasons why vacationing off-season is a good choice, with the most important being fewer crowds and more favorable prices. But where to vacation and still be able to swim off-season?
Where to vacation in Greece in May?
In May, the sea water temperature in some Greek cities is above 20°C, which is sufficient for a pleasant swim. Based on average observations of water temperature over the past ten years, the warmest sea in Greece in May was 20.5°C on the island of Kastelorizo. The warmest locations for swimming in Greece in May are usually found on the southern islands, where sea and air temperatures are higher compared to the northern parts of the country. Here are a few examples:
- Crete - Crete is one of the warmest places in Greece in May. The sea temperature in Crete in May can reach around 20-21°C\, while the average daily air temperature ranges from 20 to 25°C. Nights are cooler\, but the days are warm and sunny\, making Crete an ideal place for early summer vacations.
- Rhodes - Rhodes\, known for its sunny days\, also offers warm temperatures in May. The average sea temperature can be around 19-21°C\, and the air temperature around 20-24°C.
- Kos - On the island of Kos\, the sea temperature in May ranges around 19-21°C. The average daily air temperature is around 20-23°C\, making the island pleasant for beach stays.
- Santorini - Although Santorini may not be the first choice for classic beachgoing due to its rocky beaches\, the sea temperature in May ranges around 18-20°C\, and the daily air temperature is similar to Kos and Rhodes. All the other Cycladic islands are suitable for spring vacations. It is important to note that temperatures can vary from year to year, and it is recommended to check the current weather forecast before traveling. Also, the water may be slightly colder in the morning and evening, while it is more pleasant for swimming during the day.
Temperature on the Ionian Islands and Ionian Coast in May
Sea temperature: In Lefkada and the Ionian coast including Parga, the sea temperature in May usually varies from around 18°C to 21°C. Although the sea is slightly cooler compared to summer months, many tourists visit the Ionian coast in May for swimming, especially towards the end of May. Air temperature: Average daily air temperatures in May range from 20°C to 25°C. Nights can be cool, so it is advisable to bring warmer clothing. May in Lefkada and Parga and generally on the Ionian islands and Ionian coast offer pleasant weather for vacations, with fewer crowds compared to the peak tourist season. This time of year is ideal for those who want to enjoy the natural beauty, historical sites, and quieter beaches.
Is it warmer in May in the Ionian or Aegean Sea?
Temperatures on the Aegean coast are similar to those on the Ionian coast in May.
- Believe it or not, the Aegean Sea can be slightly cooler compared to the Ionian Sea.
And here’s why: Halkidiki is located at around 40° north latitude, while Lefkada is at around 38°. In addition to being further north, Halkidiki is “immersed” in the northern Aegean, which is under more direct influence of colder water masses coming from the Dardanelles and Black Sea currents. The Ionian Sea is connected to the deep and warmer Mediterranean to the south. Depth vs. Shallows
- Lefkada: The western coast has huge depths close to the shore. Although it warms up more slowly in the summer, it retains heat more and loses it slower during winter, so it starts with a bit more “warmth” in the spring.
- Halkidiki: The bays (Toroneos, Singitikos) are shallower. They will probably surpass Lefkada by the end of May because shallow water heats up faster in direct sunlight, but currently, after winter, that water mass is still cold.
In both cases, May is a month that offers a lot - pleasant temperatures, fewer crowds, and the opportunity to truly experience the beauty and charm of Greece. Whether you choose the Ionian or Aegean coast, May can be an ideal time for a real vacation.
Vacationing in May in Lefkada or in Halkidiki - sea and air temperature
| Location | Air Temp (Day) | Air Temp (Night) | Sea Temp (Average) |
|---|---|---|---|
| Lefkada | 22°C – 24°C | 15°C | 18.5°C |
| Halkidiki | 21°C – 23°C | 13°C | 17.5°C |
The data in the table is based on average temperatures measured in the last 20+ years. Although sea and air temperatures are similar in both places, Halkidiki may have slightly cooler nights due to its more northern location. Both places offer pleasant spring conditions with fewer crowds and are ideal for visitors looking for a quieter vacation. There are swimmers in May, but do not expect bathing like in the season. Only the bravest swim. Splashing and all-day bathing do not.

In short about vacationing in May
- Ionian Sea (Lefkada/Parga): More stable, warmer start of the season, greener nature.
- Aegean Sea (Halkidiki): Cooler nights, more northern position, shallows heating up faster only in June.
- Common: May is for exploration, peace, and a “quick” refresh in the sea, not for all-day water activities.
