Venezuela is entirely located in the tropics over the Equator to around 12° N. Its climate varies from humid low-elevation plains, where average annual temperatures range as high as 35 °C (95.0 °F), to glaciers and highlands (the páramos) with an average yearly temperature of 8 °C (46.4 °F). Annual rainfall varies from 430 mm (16.9 in) in the semiarid portions of the northwest to over 1,000 mm (39.4 in) in the Orinoco Delta of the far east and the Amazonian Jungle in the south. The precipitation level is lower in the period from November to April and later in the year from August to October. These periods are referred to as hot-humid and cold-dry seasons. Another characteristic of the climate is this variation throughout the country by the existence of a mountain range called "Cordillera de la Costa" which crosses the country from east to west. The majority of the population lives in these mountains.
