The climate in the Sierra de Las Nieves Natural Park is generally mild. Average temperatures range from 10ºC to 17ºC, with rainfall of over 800 mm per year in the lower regions and reaching 1,700 mm at the Quejigales weather station. For several weeks of the year, snow is a regular feature above 1,600 metres.
Rainfall is predominant between October and March, whereas in the summer period, rain is practically non-existent (less than 15mm). Such a prolonged dry period is highly influential over the flora, as is the altitude of a considerable area of the Natural Park.
The snow that falls in winter is a consequence of the northerly winds that at other times of the year also provide most rain, especially in the north of the region.
