Forecast models from the European Centre for Medium-Range Weather Forecasts and Global Forecast System place Warsaw’s maximum temperature for September 11 near 17–18°C, driving the tight market split between those two outcomes. A stable high-pressure ridge with light southerly flow and partial cloud cover limits daytime heating, while modest Atlantic moisture keeps surface temperatures from rising further. Minor differences in predicted cloud thickness and wind speed between model runs account for the near-even implied probabilities. Historical September averages for the city hover around 18°C, providing climatological context for the current consensus. Updated model guidance and local observations tomorrow morning will refine the exact peak before the market resolves.

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.
