This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 31 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 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. 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 forecasts from meteorological agencies point to a daytime maximum of 26–28°C in Istanbul on August 31, sustaining the near-even split between 26°C and 27°C in trader positioning. Northeasterly flow under high pressure supports partly cloudy skies and moderate daytime heating, with afternoon peaks shaped by light winds and regional sea-breeze effects that limit further warming. Model consensus places the most likely high near 27°C, though small shifts in cloud cover or wind timing could tip the observed peak one degree either way. Historical late-August averages hover around 29°C, underscoring how current patterns are suppressing the upper end of the distribution ahead of tomorrow’s official readings.
