Seasons in Paraguay

Paraguay is located in the middle of South America thus its climate is diverse. Eastern regions have wet tropical weather conditions while north-western areas are lying in the zone of dry tropical climate. Order of seasons is reversed in relation to the North Hemisphere and on top of it year is roughly divided into wet and dry seasons.

Local summer (November to March) is warm with possible peaks up to 43 °C (109 °F) in north-western portion of the country. Winter (April to October) is cooler with possible leaps of temperatures depending on prevailing air masses. Warm Amazonian air is followed by cold Antarctic masses making weather rather unpredictable. Range of annual amount of precipitation is wide: from 700 mm (27.5”) in western regions to 2000 mm (78.7”) in eastern mountains.

Summer in Paraguay

Whole season is the best time to visit the country. Though average temperature range is between 22 and 25 °C (72-77 °F) overall weather conditions are rather unpredictable due to movement of cold and warm air masses so travelers should be prepared for both warmth of 30 °C (86 °F) and coolness of 6 °C (43 °F).

Autumn in Paraguay

September is the last change in a year to visit the country while weather hasn’t spoiled. Comparing to previous months September is bit rainy yet actual rainy season starts at October. Oddly enough other weather parameters may seem as perfectly fine for vacation – temperature slowly rises as well as amount of hours of sunlight per day.

At November precipitation is at its peak. Showers usually occur at afternoons and nights providing morning chill. In addition at November thunderstorms are coming to the country. Thus combination of weather conditions make visit to Paraguay uncomfortable.
