I am often asked, “When is the best time to Travel to Santorini? Is there a Rainy season?”.
Well, according to the scientists, there's a dry season that corresponds to summer (Apr-Oct) and a rainy season in winter (Nov-Mar).
My personal experience has been that the rainy season means absolutely nothing.
It is rare for the weather to rain continuously for days!!
The best weather is often found in April, May, September and October. These are also the months when you can find some good travel bargains.
