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 Mar '26. The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column on the specified date once information is finalized for all hours on that date, 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 to "Yes" until data for this date has been finalized. 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Official NOAA observations at Istanbul Airport confirm the highest temperature on March 31, 2026, reached exactly 17°C, driving trader consensus to a near-certain 100% implied probability for that outcome amid $207K in volume. This reading, warmer than the March climatological average of 11–12°C, reflects partly cloudy skies, light southerly winds, and radiative heating during midday hours, consistent with Turkish State Meteorological Service reports of seasonal norms slightly elevated by transient high-pressure influence. While awaiting final data certification, realistic challenges—such as post-hoc measurement revisions from quality control or discrepancies across urban heat island-affected stations—remain improbable given synchronized real-time METAR logs and model hindsight validation. Upcoming hourly breakdowns from NOAA will solidify resolution.
