Warsaw, Poland's capital city, experiences variable spring weather as April transitions into late spring. Daily high temperatures in mid-April typically range between 10–16°C, though specific daily highs can fluctuate significantly based on weather systems moving across Central Europe. April 18 falls at the tail end of spring, when weather forecasting becomes increasingly uncertain beyond a few days out. This market asks whether the highest temperature recorded in Warsaw on April 18 will be exactly 13°C—a specific pinpoint prediction rather than a range. The current 0% YES odds suggest traders believe either the temperature will be warmer or cooler than 13°C, or that exact-temperature predictions are intrinsically difficult to resolve. Historical weather data for Warsaw and current forecast models provide the basis for resolution. The odds distribution reflects low conviction that this precise temperature will materialize, indicating traders expect the high to deviate from this specific mark.
