Current Climate 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. Data for  specific coordinates can be downloaded for in the Data Download page.

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.

Climate Data Historical

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.

Temperature

  • The largest increments in annual average temperature were observed in the coldest regions (Western Highlands) with increases between 9.4 and 10.3%; in the warmer regions (Pacific and Caribbean) increases observed were lower, between 0.8 and 1.5%. 

Precipitation

  • All regions show increase in rainfall. In the North region, a 48% increase is reported, while the Caribbean and Transversal del Norte regions show smaller relative increments, between 2.3% and 9.6%. An 18% increase (with a variation between 13.2 and 27.6%) was reported in the rest of the climate regions. 

This section provides the options to visualize historical climate data for different timeframes via map and annual cycle chart.
