Recent forecasts indicate a cooling trend for Istanbul on September 13, with daytime maxima likely near 24–26°C amid increased cloud cover, scattered showers, and northerly winds that limit solar heating and enhance mixing. This follows sunnier, warmer conditions on September 12 near 28–29°C. Model consensus from GFS and similar runs highlights modest precipitation chances and higher humidity as key suppressors of peak temperatures, creating tight clustering around 22–24°C outcomes. Traders appear to weigh the precise timing of any frontal passage or cloud buildup, which could differentiate between 22°C and 23°C resolution thresholds versus slightly higher readings if clearing occurs earlier. Updated model guidance through the evening of September 12 will further refine these variables ahead of market close.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 13 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=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.Recent forecasts indicate a cooling trend for Istanbul on September 13, with daytime maxima likely near 24–26°C amid increased cloud cover, scattered showers, and northerly winds that limit solar heating and enhance mixing.
