This market will resolve to the temperature range that contains the highest temperature recorded at the Warsaw Chopin Airport Station in degrees Celsius on 11 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Warsaw Chopin Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/pl/warsaw/EPWA. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve to "Yes" until all data for this date has been finalized. The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Official observations from the Warsaw Chopin Airport weather station (EPWA), the standard reference for such markets, recorded a maximum temperature of 12°C on April 11, anchoring trader consensus at 100% implied probability for this outcome. Cool northerly winds and extensive cloud cover limited solar heating throughout the day, consistent with Institute of Meteorology and Water Management (IMGW) synoptic reports and ECMWF model runs forecasting highs of 11–13°C amid a transitional spring pattern. April climatological averages near 13°C provide context for this mild variability, with no significant deviations noted. Rare post hoc data revisions from quality checks represent the only realistic challenge, though initial airport telemetry is highly reliable.
