Forecast models from multiple sources indicate mostly clear to partly cloudy skies and light northeast winds over Istanbul on September 21, supporting peak temperatures of 25–26 °C as high pressure maintains stable conditions ahead of an approaching frontal system. This setup favors the closely matched 25 °C (49 %) and 24 °C (46 %) outcomes, with small differences arising from model variations in afternoon cloud cover, boundary-layer mixing, and exact timing of the subsequent cooling trend. Historical September maxima near 24–25 °C provide context, while the expected shift to rain and lower readings by September 22 limits upside potential beyond 26 °C. Updated runs from agencies such as NOAA and ECMWF will refine the precise maximum before resolution.

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=LTFM
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.
