Recent forecasts from global models including GFS and ECMWF indicate Istanbul will see a high near 21–22°C on September 22 amid northerly flow, extensive cloud cover, and widespread rain that limits solar heating. Official guidance points to daytime maxima around 21°C with gusty winds further suppressing temperatures, aligning with the market’s heaviest weighting on 21°C. This setup reflects a classic post-summer cooling pattern for the region, where precipitation and reduced insolation typically cap highs 3–5°C below clear-sky September norms. Updated model runs through September 21 show minimal spread, keeping 20–22°C outcomes dominant while lower or higher extremes remain low-probability outliers absent major forecast shifts.

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.
