Buenos Aires experiences autumn weather in April, with typical highs ranging from 21°C to 24°C depending on wind patterns and continental air mass influences. April 20, 2026, sits at the tail end of Buenos Aires' autumn season, when temperatures can be volatile due to seasonal shifts between warm and cool air masses. This market asks whether the city's highest temperature on that specific date will be exactly 22°C—a prediction that requires precision, as forecasts at this granularity are inherently uncertain and sensitive to small changes in atmospheric conditions. The resolution will use official meteorological data from Argentina's national weather service (Servicio Meteorológico Nacional), ensuring a transparent and objective outcome. A 33% YES probability suggests traders view an exact 22°C high as possible but less likely than alternative outcomes like 21°C, 23°C, or 24°C. This reflects the probabilistic nature of daily temperature forecasts: while 22°C is well within the normal April range for Buenos Aires, hitting that specific value with precision requires converging conditions across wind speed, cloud cover, and solar radiation. Weather markets like this reveal collective expectations about atmospheric dynamics over a narrow time window.
