Climatology
This page presents Guyana'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.
Guyana enjoys a wet tropical climate with warm temperatures and abundant rainfall without the extremes of hot or cold. Temperature ranges between 16°C and 34°C with lower temperatures in the higher regions. Air temperatures range between 16°C and 34°C with lower temperatures in the higher regions. Temperatures on the coast range between 22°C and 31°C due to the stabilizing effect of the sea and the North Eastern Trade Winds. These Trade Winds flow over the coast with speeds averaging ten miles per hour, and decrease as they move further inland where light winds generally prevail.
