Climatology
This page presents Guatemala's climate context for the current climatology, 1991-2020, derived from observed, historical data. Information should be used to build a strong understanding of current climate conditions in order to appreciate future climate scenarios and projected change. You can visualize data for the current climatology through spatial variation, the seasonal cycle, or as a time series. Analysis is available for both annual and seasonal data. Data presentation defaults to national-scale aggregation, however sub-national data aggregations can be accessed by clicking within a country, on a sub-national unit. Other historical climatologies can be selected from the Time Period dropdown list.
Observed, historical data is produced by the Climatic Research Unit (CRU) of University of East Anglia. Data is presented at a 0.5º x 0.5º (50km x 50km) resolution.
Guatemala's climate is not marked by normal seasons of the northern hemisphere, but by a rainy season (May to October) and the dry season (November to April). The rainy cycle occurs when establishes the regime of the trade winds of the northeast and, subsequently, when the zone intertropical convergence approaches these latitudes. From the end of August, the rainy season produces intense rainfall. The characteristics of the climate during dry season are determined by masses and cold migratory fronts.
