Crete falls into two climatic zones, with the largest part of the island falling into the Mediterranean and the south coasts and Gavdos island falling to the North African. It has one of the healthiest climates for humans to live as it is quite humid near the sea, with short mild winters and cool summers. While the far south has subtropical weather during summer, and inland alpine areas of the three major massifs can be as cold as -10°C (14°F) in winter, most of the inhabited areas lie close to the coast, which means mild temperatures.
The average Crete temperature decreases as you travel north. July and August are the warmest months, and January is the coldest month of the year. In summer, the average maximum temperature ranges between 20-30ºC (70-90°F) and in winter between 10-15ºC (50-60°F).
Seasons and clothing requirements
Summer: June – August Summer in Crete is moderate to hot, with temperatures hovering around 20-30 degrees celsius and clouds almost nowhere. In most places you can wear shorts and a t-shirt or singlet during the day, adding a light jumper at night. In dry south shores, sun get warmer and you should always wear hats, sunglasses and have water with you.
Autumn/Fall: September – November Temperatures during this time are a little cooler than summer but the Crete weather can be excellent. Suitable clothing includes light pants or shorts, and a t-shirt or long-sleeved top. It can cool off at night more during this season, so make sure you are prepared with a warm sweater, especially in the mountainous areas.
Winter: December – February Winter in Crete brings colder weather to much of the island, with snow in the mountains and rain in the rest areas, but still sunny days are very common. You’ll need jeans, long-sleeved tops and coats in most places, and if you’re heading into the snowcapped mountains, gloves and thick sweaters are also a good idea.
Spring: March – May Spring brings weather of all types – expect everything from cold, frosty, clear days to sunny and hot. Make sure you are prepared for this type of weather if you are visiting during this time. Jeans are good and layers work well on top, as they can be added and removed depending on what the weather brings.
