The Weather in Sitges is quite unique. Even though it is 20 mins from Barcelona, the fact that it is surrounded by mountains gives Sitges its very own micro-climate. So on days when it is pouring rain in Barcelona, clear blue skies and temperatures of 30 degrees (July/Aug) are the norm for Sitges.
The climate in Sitges is mild, with no extreme temperatures, cool but not cold in the Winters, and softer more pleasant temperatures in the Summer. Some would say the perfect weather.
The privileged location of Sitges allows this village to enjoy mild Winters, with a few rainy days but not many, and with temperatures around 15ºC. The Spring and Autumn are seasons of sun, and the temperatures are usually around 20ºC. Spring and Autumn see the most rain while the Summer is hot with temperatures of about 30ºC. This special climate in Sitges is due to its location between the Macizo del Garraf and the closeness of the Mediterranean sea.
