**Clear skies, light southerly winds, and a stable warm air mass are positioning Warsaw for a daytime high near 28–29 °C on September 9.** Official forecasts from multiple models show peak temperatures climbing from morning readings around 20 °C to afternoon maxima of 27–29 °C under minimal cloud cover and low precipitation chances during peak heating hours. This aligns closely with the prior day’s observed high of 28.1 °C, supporting trader emphasis on the 29 °C outcome at 49.5 % implied probability, followed by 28 °C (24.5 %) and 30 °C (20.5 %). The narrow spread reflects model consensus on modest daytime warming without strong advection or convective suppression, with only a slim chance of exceeding 31 °C before cooler, rainier conditions arrive on September 10.

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 9 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.**Clear skies, light southerly winds, and a stable warm air mass are positioning Warsaw for a daytime high near 28–29 °C on September 9.** Official forecasts from multiple models show peak temperatures climbing from morning readings around 20 °C to afternoon maxima of 27–29 °C under minimal cloud cover and low precipitation chances during peak heating hours.
