Paraguayan autumn will be marked by thermal oscillations and days of intense cold, while winter brings uncertainty over the arrival of the El Niño phenomenon. The analysis comes from the director of Meteorology and Hydrology of the National Directorate of Civil Aeronautics (DINAC), Eduardo Mingo.
So far, the Chaco region records the lowest temperatures of the season. This Tuesday, the departments of Presidente Hayes and Boquerón reached lows of 3°C, shortly before dawn, when readings usually consolidate.
According to Mingo, the current cold air mass should remain stable for a few days. “We observe cycles of three to five days with low temperatures, followed by a slight and partial thermal rise,” he explained. This pattern will soon be interrupted by a system that will bring rain, alternating intense cold with instability and precipitation – typical behavior for the rest of autumn.
The biggest doubt among climate analysts lies in winter. The global ENSO (El Niño-Southern Oscillation) indicator is in a neutral phase, which explains current conditions. However, macroclimate models point to a transition toward the El Niño phase between July and August, at the peak of winter. Historically, the phenomenon tends to raise temperatures above the seasonal average. Mingo, however, is cautious: during the transition from autumn to winter, the most likely scenario is that the cold and harsh days of the season will continue.
