Climate of Paraguay

During the winter, the dominant wind is the cold pampero from the South Atlantic, which blows across Argentina and is deflected northeastward by the Andes in the southern part of that country.

Because of the lack of topographic barriers within Paraguay, these opposite prevailing winds bring about abrupt and irregular changes in the usually moderate weather.

In transitional months of April and September, temperatures below the midsummer averages include nocturnal minima that may dip below freezing.

During July, the coldest month of the subtropical winter in the Southern Hemisphere, temperature averages about 17.87 °C (64.17 °F) in Asunción and slightly cooler on the Paraná Plateau.

No part of the Paranaense region is entirely free from risk of frost and consequent damage to crops, and various locations report snow flurries occasionally.

Although local meteorological conditions play a contributing role, rain usually falls in dominant tropical air masses.

In 2017, youth activist Diana Vicezar established a community-based organisation designed to tackle elements of the climate crisis and animal welfare.
