Hi Swati Mishra, Santorini in May (60% Crowded) There's a big difference between •Early May (when cool overcast days can still be common) • late May (when the days are consistently sunny and warm). May is the month when the beach towns dust off the cobwebs and open for business. Average Max Temperature: 22°C. Average Rainfall: 7mm. fell free to contact for collaboration for this trip 😊🏝
Almost everything gets open in Santorini by the mid of May, So I am sure that you will have fun during that time, As far as for me I actually visited this place in October and the temperature during this time 22 C
