Current Climate


This page presents Paraguay'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.

Paraguay’s climate overall is characterized by high humidity and warm temperatures year-round, with hot and rainy summers, and mild winters with significant temperature variability that can bring both frosts to practically the entire national territory, as well as heat waves. Annual temperatures increase from south to north, while rainfall decreases from east to west. Warm temperatures are present throughout most of the year, as average annual temperatures exceed 20°C throughout the country. In the Eastern Region, the annual average temperature is between 20°C and 24°C, while in the Chaco or Western Region, average annual temperatures hover around 25°C. The two periods of maximum rainfall in most of the country are from March to May and from October to November. Downpours are common from September to April, where a large amount of rain falls in a few minutes and generally this occurs when tropical air masses are dominant, and humidity is high. Light rains are common during the winter months, from May to August.
