The climate of Paraguay consists of a subtropical climate in the Paranaense region and a tropical climate in the Chaco.^[1] The Paranaense region has a humid climate, with abundant rainfall throughout the year and only moderate seasonal changes in temperature.

The seasons in Paraguay are opposite to those in the northern hemisphere, meaning northern summer is Paraguayan winter, and vice versa.

During summer, the dominant influence on the climate is the warm sirocco winds blowing out of the northeast.

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. Winds are generally brisk. Velocities of 160 kilometres per hour (99 mph) have been reported in southern locations, and the town of Encarnación was once leveled by a tornado.
