Current forecasts from multiple models, including GFS and ensemble guidance, indicate Istanbul will experience mostly clear skies with northeasterly flow on September 10, supporting daytime highs near 27–28°C and overnight lows of 18–21°C under stable high pressure. This places the expected minimum in a narrow band around 20°C, consistent with seasonal norms but slightly above the long-term September average low of 17°C. Trader sentiment remains closely split between outcomes above 27°C and 17°C or below because small shifts in wind speed, cloud cover, or the timing of any subtle cold-air advection could alter nocturnal radiational cooling rates by several degrees. Upcoming model runs and surface observations over the next 48 hours will likely resolve the primary uncertainty in boundary-layer conditions.

This market will resolve to the temperature range that contains the lowest 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 lowest 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.Current forecasts from multiple models, including GFS and ensemble guidance, indicate Istanbul will experience mostly clear skies with northeasterly flow on September 10, supporting daytime highs near 27–28°C and overnight lows of 18–21°C under stable high pressure.
