Best time to go to Oia
You’re all but guaranteed good weather in Greece in the summer. Temperatures are usually in the 30s, plus you can expect about 12 hours of sunshine a day. And as for rain, you’ll hardly see a drop in July and August. If you prefer things a bit cooler, spring and autumn see plenty of sun, but temperatures are a bit more comfortable, in the mid-20s. These shoulder months are a great time to visit if you’re into walking or sightseeing, as it’s not too hot, even in the peak of the day. You might experience some rain showers from time to time, too.
