Latest numerical weather prediction ensembles from global models place 22°C as the leading outcome for Istanbul’s September 14 high, with 47% implied probability, driven by a stable anticyclone and moderate northerly flow that limits daytime warming. This consensus reflects current 500 hPa heights and surface pressure patterns consistent with early-autumn climatology, where historical mid-September maxima average 24–26°C but recent runs show a modest cooling signal from upstream Atlantic troughing. Short-range forecast uncertainty remains, particularly regarding cloud cover and any weak warm advection; traders will watch the next ECMWF and GFS cycles plus local Turkish Meteorological Service guidance for revisions before the market resolves.

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.
