Recent forecasts from multiple meteorological models indicate a high of 21°C for Istanbul on September 22, aligning with the market's strongest implied probability at 64.5%. A cooler northerly airflow and associated frontal system are driving this outlook, bringing increased cloud cover, scattered showers, and suppressed daytime maxima compared to the 25–26°C readings observed on September 20–21. Ensemble guidance shows limited spread around 20–22°C, reflecting typical late-September variability under such patterns, while historical September averages near 24°C provide context for the expected dip. Updated model runs and official briefings over the next 48 hours will refine precipitation timing and any residual warming potential 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.
