Buenos Aires experiences autumn in April, with typical high temperatures ranging between 12 and 22 degrees Celsius. The question asks whether the recorded high temperature will measure exactly 18 degrees Celsius on April 20, 2026. With current YES odds at zero percent, the prediction market consensus indicates this specific temperature is assigned extremely low probability on the specified date. This zero-percent pricing could reflect trader expectations that April temperatures will trend warmer or significantly cooler than this midpoint, or that the actual recorded measurement will land between whole-number increments. The market resolves based on the official high temperature recorded by Buenos Aires' primary meteorological station for April 20. Because this market requires an exact-match outcome rather than a temperature range, the resolution criteria are strict—the recorded high must measure exactly 18 degrees Celsius, not 17.5 or 18.5. Historical April weather patterns in Buenos Aires show considerable day-to-day variance, which partly explains the zero-percent odds; traders assign vanishingly low probability to hitting this narrow, precise target. The market's near-zero pricing suggests the market perceives broader temperature ranges as significantly more probable outcomes for this specific date.
