Frost risk on the altiplano: a forecast for the countryside

On the Bolivian altiplano, frost can occur for much of the year, especially between May and August, on clear, calm nights. The altitude drives the temperature well below zero by dawn.

Impact on the countryside

An out-of-season frost damages key crops such as potatoes and quinoa, and stresses livestock. Communities combine traditional techniques with the forecast to reduce losses.

How to plan ahead

• Watch the forecast minimum temperature for the early morning.
• Risk is highest with clear skies, dry air and calm wind.
• Schedule irrigation or crop covers one or two days in advance.
