This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 28 Aug '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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source. 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.**Northerly winds and increased cloud cover with scattered showers are suppressing daytime heating in Istanbul ahead of August 28, shifting model consensus toward a maximum temperature near 24–26°C.** Official forecasts from the Turkish State Meteorological Service and international guidance (ECMWF, GFS) indicate a high around 26°C, with some runs showing 24–25°C under thicker cloud and light rain that limits insolation. This marks a cooldown from recent 29–30°C readings driven by clearer, warmer southerly flow. Ensemble spread remains modest but favors outcomes at or below 26°C, consistent with climatological late-August norms of ~27°C when modified by transient northerly advection. Updated model runs and the next NHC/NOAA-adjacent regional briefing will refine the exact peak before market resolution.
