This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 4 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 from multiple meteorological models and station observations position Istanbul's September 4 high near 26–27°C, with afternoon readings climbing toward 27°C under mostly clear skies and moderate northeasterly winds. This aligns with early September climatology, where average daily maxima hover around 23–27°C before seasonal cooling accelerates. Current conditions, including dew points near 17°C and low precipitation probability, support modest warming without strong advection of hotter air masses. Trader consensus heavily favors 26°C as the implied outcome, reflecting model consensus on peak values and historical resolution patterns for similar transitional days, though slight upward revisions in some runs keep 27°C viable pending final official measurements.
