What's the temperature like in Mykonos during May?

The temperature is extremely stable in May with average highs of 20℃ and lows just 2℃ lower at 18℃. The UV index will be high at this time of year, so protection against skin and eye damage is needed. Try to limit exposure between 10am and 4pm. Apply broad spectrum SPF 30+ sunscreen every few hours, even if it's cloudy, or more frequently after sweating or swimming, and wear UV-blocking sunglasses too, and bear in mind that bright surfaces, such as sand and water increase UV exposure.

Does it rain in Mykonos during May?

On average, there will be 2 rainy days during the month, amounting to 30.8mm in total. That's much drier than we see in England during August, and therefore not something to be concerned about. There's a small chance that you'll catch a thunderstorm during your trip.

Is it windy in Mykonos during May?

You're unlikely to experience any strong winds. Expect a gentle breeze that increases to moderate at times during May. With warm air temperatures and high humidity, any breeze will feel warm but refreshing.

How warm is the sea in Mykonos during May?

The water around Mykonos is around 19℃ during May. It will feel a little on the cool when first entering, but you'll warm up quickly. Most kids will have no problem with this temperature, but those who feel the cold are unlikely to want to swim.
