**Forecast models from GFS and ECMWF indicate a daily maximum near 27°C in Istanbul on September 12 under clear skies, moderate northeasterly winds, and high pressure promoting subsidence warming.** Recent runs show afternoon peaks of 26–29°C depending on station location and exact timing of the diurnal maximum, with limited cloud cover or sea-breeze moderation keeping values tightly clustered. This narrow spread explains the near-even market split between 25°C and 26°C, as traders weigh minor model differences, urban heat effects versus official airport readings, and historical September norms around 25–28°C. Updated guidance later today or tomorrow could shift the implied probability if any ensemble member diverges on wind strength or boundary-layer mixing.

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.
