Where to go for the heat you prefer

Santorini is the coolest destination listed, averaging 25°C by day, so it is the better fit if you prefer gentler warmth. At the other end, Skala reaches 34°C: choose it for heat rather than comfortable midday walking. Athens averages 33°C, making early starts and shaded breaks sensible if you plan to spend much time outside. Crete, at 31°C, is also firmly hot rather than mild. Sissi and Stalis have warmer nights than Hersonissos and Koutouloufari, though the difference is small. Choose your destination around your daytime heat tolerance first; none of these warmer options offers much relief simply by waiting until evening.

What the weather means for your day

With 13.4 hours of sunshine and an average of 1 rainy day, July favours outdoor plans without much need to organise the day around showers. The catch is prolonged exposure to sun and heat. Keep walking and more active plans for the morning or later afternoon, leaving midday for shade, rest or a meal out of direct sun. Pack loose, light clothing, a sunhat and sun protection, and carry drinking water. Nights average 23°C, so do not expect evenings to feel crisp; light clothes should remain useful after sunset. If warm nights disrupt your sleep, prioritise accommodation with air conditioning.
