This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 2 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 which 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 can not resolve until the first data point for the following date has been published on the resolution source. 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 official forecasts and real-time observations for Istanbul on September 2 indicate mostly sunny conditions under a stable high-pressure system, with northeast winds of 10–25 km/h moderating daytime heating. Hourly model guidance shows temperatures rising from morning lows near 21°C to afternoon peaks of 28–29°C, consistent with early-September climatology for the region. The tight split between 26°C and 27°C market-implied odds reflects lingering uncertainty in exact peak timing, slight model-to-model differences in boundary-layer mixing, and potential microclimate effects at the official measurement station, where urban heat or wind gusts could trim the maximum by 1–2°C from broader guidance. No significant frontal systems or cloud cover are expected to alter the trajectory before resolution.
