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.
