This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 5 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 atmospheric conditions over Istanbul, including clear skies and light northeasterly winds under a stable high-pressure system, support a daytime maximum near 27–29 °C according to consensus from numerical weather models. Official forecasts from regional meteorological services project a peak in this range for September 5, consistent with typical early-September climatology of 23–27 °C averages. Trader emphasis on the 27 °C outcome reflects observed morning temperatures and limited afternoon heating potential, while modest probabilities for 28–29 °C capture residual model spread and possible localized warming. With the day progressing toward resolution, updates from ground stations will determine the final recorded high.
