This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Warsaw Chopin Airport Station in degrees Celsius on 2 Sep '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=epwa If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source. In the event which there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket. To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C. This market can not resolve until the first data point for the following date has been published on the resolution source. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
Forecasts for Warsaw on September 2 indicate a high near 22–23°C under partly cloudy skies, stable high pressure near 1019 hPa, and light westerly winds, driving the near-even market split between those outcomes. Moderate solar radiation under variable cloud cover, combined with advection of mild Atlantic air masses, supports daytime warming above the early-September climatological average of roughly 18–20°C while limiting stronger heating. Low precipitation chances and moderate humidity further constrain peak values, with minor model differences in afternoon cloud timing or boundary-layer mixing explaining the tight 22°C versus 23°C probabilities. Official measurements at the primary station will resolve the market once the daily maximum is recorded.
