Recent ensemble forecasts from sources including GFS and ECMWF indicate a daily maximum of 26–27°C for Istanbul on September 10 under clear to partly cloudy skies, moderate northeasterly winds of 10–20 km/h, and negligible precipitation risk. This positions 25–26°C as the leading market outcomes, consistent with the narrow spread across model runs and climatological September norms near 23–27°C. Stable high-pressure conditions and the absence of significant frontal systems or moisture advection over the past 48 hours have kept probabilities anchored, with traders weighting official monitoring thresholds and minor ensemble spread in afternoon peak readings. Updated model guidance expected in the next 24 hours could refine the exact maximum.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 10 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 ensemble forecasts from sources including GFS and ECMWF indicate a daily maximum of 26–27°C for Istanbul on September 10 under clear to partly cloudy skies, moderate northeasterly winds of 10–20 km/h, and negligible precipitation risk.
