Buenos Aires, the capital of Argentina, experiences mild autumn weather during mid-April with typical daily high temperatures ranging between 18°C and 22°C, making 20°C fall within the expected seasonal range. This market specifically tracks whether the highest temperature recorded on April 19, 2026, will be exactly 20°C—a narrow, precise outcome. The extremely low odds at 2% reflect the inherent difficulty in predicting such exact weather outcomes; prediction markets typically see better participation around rounder thresholds or broader ranges, and this specific precise target has attracted minimal trading interest to date. At 2% implied odds, traders are pricing in approximately a 1-in-50 chance of Buenos Aires reaching this exact benchmark temperature. Weather prediction markets like this resolve based on official meteorological data from Argentina's national meteorological service (Servicio Meteorológico Nacional), ensuring outcomes are independently verifiable and not subject to dispute. The current modest price and low volume suggest traders view a 20°C exact high as unlikely compared to nearby temperature outcomes. This market closes at 00:00 UTC on April 19, 2026, when official weather records will determine the final resolution.
