This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 15 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 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 short-range forecast guidance from regional models shows a modest cooling influence from increased cloud cover and enhanced sea-breeze circulation, positioning 26 °C as the most probable daily maximum in Istanbul on August 15. This aligns with the market’s strong 58 % implied probability for 26 °C and 25 % for 25 °C, while trimming odds for 27 °C and higher. Typical late-August climatology favors highs near 28 °C, but current runs emphasize slightly suppressed afternoon temperatures amid partly cloudy skies and moderate northerly winds. Updated model consensus and any revisions to boundary-layer moisture or wind timing in the next 24–48 hours remain the key variables that could shift these probabilities ahead of market resolution.
