This market will resolve to the temperature range that contains the highest temperature recorded at the Warsaw Chopin Airport Station in degrees Celsius on 18 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.Trader consensus on Polymarket has locked in 18°C as the highest temperature in Warsaw today at 100% implied probability, driven by the latest forecast ensembles from ECMWF, GFS, and Poland's Institute of Meteorology and Water Management (IMGW), which converge on a midday peak of 17-18°C amid northerly winds capping warming potential. Official IMGW synoptic guidance specifies maxima around 15-18°C in central Poland, aligning with current observations of morning lows near 7°C, variable cloud cover, and moderate insolation under a cool upper-air pattern. This positions well above April's climatological average high of 13°C. Realistic challenges include prolonged clear skies enhancing solar heating to 19°C+, though model agreement and persistent breeze make this unlikely; final resolution awaits official Warsaw station data by midnight.
