**Forecast models for Warsaw on September 13, 2026, cluster around a daytime maximum of 19–21 °C under mostly cloudy skies and southwesterly flow.** Multiple global and regional runs, including GFS-derived guidance and ECMWF outputs, indicate afternoon temperatures peaking near 20 °C, with some ensembles reaching 21 °C where breaks in cloud cover allow greater solar heating. Light-to-moderate southwest winds (roughly 7–10 km/h) promote mild advection of warmer air from the south while limiting strong radiative cooling overnight, keeping minimums in the low-to-mid teens °C. Slight model spread arises from differences in predicted cloud thickness and exact wind speeds, which directly affect the surface energy balance and the final observed high. Historical September averages near 16–18 °C provide context that current conditions are mildly above normal. Resolution depends on the official maximum recorded at the Warsaw station, with final model updates and real-time observations expected to narrow remaining uncertainty before the close of trading.

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.
