Since the area is closed to the cold northerly winds, it is characterized by the typical Mediterranean climate with hot, dry summers and moderately warm and rainy winters. Around 300 days of the year are sunny, the sea temperature never goes below 15°C and in summer is around 28°C. The temperature can climb into the 40°Cs in July and August but low to mid 30°Cs is more typical. The sea breeze and the northeasterly winds blowing from inland help to make the high temperatures more bearable.
People come to Antalya all throughout the year because it is a place with a relatively mild climate, known for being sunny more often than it is not. What should be known by travelers is that the summer months can get very warm, and some find them almost uncomfortably hot. The average summer temperature is usually around ninety degrees, but the humidity can make it feel warmer. The average temperature of Antalya’s waters at that time is approximately eighty five degrees, which some people find too warm but many find to be perfect for enjoying swimming.
The rainy season is in the winter, so visitors who prefer dry travels should make sure to avoid the wettest winter months, although the rain usually only lasts for about three weeks once the rainy season hits. It generally does not snow, though, so travelers will not have to worry excessively about the winter weather, other than the rain. The rainy season may come anytime between October and April. The coldest months are January and February which are not particularly cold in comparison with many other parts of the world at that time; average winter temperatures are around forty degrees for low temperatures and sixty degrees for high temperatures.
