Climate

Total annual precipitation

Páramo climate is basically a diurnal climate type: cold during the night and warmer during daytime according to the altitude. In the superpáramo frost occurs almost every night. Thermal seasonality is absent, only occurring the rain and dry season during the year.

The climate is rather wet on the eastern slope of the Cocuy Range with an estimated 4000-5000 mm yearly precipitation in the bamboo páramo near the upper forest line (probably there are no rain gauges here). As a consequence, the eastern slopes have much higher cloud incidence, frequent drizzle and prolonged rains. El Cocuy town at 2749 m on the western slope and in the rain shadow of the tradewind has 901.2 mm precipitation (mean over 10 years).

Temperatures Sierra Nevada del Cocuy

The IDEAM (Instituto de Hidrología. Meteorología & Estudios Ambientales) is presently monitoring the Colombian glaciers including those of the Sierra Nevada del Cocuy (IDEAM 2012). The mean maximum temperature registered by the meteorological station near Güicán at 3716 m has increased about 2° C between 1976 and 2010, while the mean temperature increased about 1° C and the mean minimum temperature went down 1-2° C in the same period.
