Recent forecasts from multiple models indicate a high near 20–21°C in Warsaw on September 18, driven by post-frontal cooling after rain and stronger westerly flow on the 17th, followed by moderate southwesterly winds, building high pressure, and extensive cloud cover that limits daytime heating. Afternoon temperatures are projected to peak in the low 20s Celsius under mostly cloudy skies with minimal precipitation risk, consistent with late-summer climatology for the region. Trader consensus clustering around 21–22°C reflects this narrow range and typical forecast uncertainty of 1–2°C arising from cloud timing and boundary-layer mixing, with new model runs and official station data from Chopin Airport likely to refine probabilities before market resolution.

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 18 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 that 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 will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.Recent forecasts from multiple models indicate a high near 20–21°C in Warsaw on September 18, driven by post-frontal cooling after rain and stronger westerly flow on the 17th, followed by moderate southwesterly winds, building high pressure, and extensive cloud cover that limits daytime heating.
