As you might expect from one of the Greek Islands, the weather in Santorini can be very hot during the summer months with little or no rainfall. In July and August Santorini weather temperatures average around 30°C. Fortunately, the temperature is moderated by the meltemi, or Northern wind.

The famous Santorini sunsets are due in part to the humidity in the Cyclades islands which can make the sky seem hazy and lead to spectacular sunsets.

The Autumn months of September, October and November are milder than the Spring months of March, April and May all over Santorini, and the sea temperature reaches its peak at this time. And even during the winter months of December, January and February there is little rainfall on the island of Santorini.

In very hot weather in June, July and August, even the Santorini people seem to suffer. Ex pats and holiday makers can have some problems with the heat of the Santorini weather. Holidays can sometimes be spoilt by sunstroke or sunburn. It’s a good idea to make sure you follow some simple guidelines to avoid problems:

Drink plenty of water! Even if you don’t feel thirsty. Use a high factor sun cream, even if it looks a bit hazy, and wear a hat. Children especially should be covered up with long sleeves and hats, and sun block on exposed skin.

Stay by the pool, or the sea – or take a nap at the height of the afternoon summer sun. Don’t do anything too strenuous around the noon day heat. Finally – drink plenty of water! Dehydration is one of the main reasons for problems experienced in the heat of the Mediterranean sun. You'll want to look like a bronzed Adonis or a glowing sexy Greek goddess not a shrivelled prune!

TOP TIPS when it's HOT!

  • Drink plenty of water
  • Use a high factor sun cream
  • Wear a hat
  • Cover up
  • Stay near the pool or the sea
  • Take a nap at noon
  • Again, drink plenty of water!
