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 Apr '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.Trader consensus on Polymarket prices 15°C as the leading outcome at 44% implied probability for Istanbul's highest temperature on April 5, reflecting the latest Turkish State Meteorological Service (MGM) and ECMWF model ensembles projecting peaks near 15-16°C amid partly cloudy skies and light southerly winds. Recent observational data from April 1-3 show stable early spring highs around 14-16°C, moderated by the Marmara Sea's thermal influence, with minimal precipitation allowing modest daytime heating. Forecast model agreement has tightened over the past 24 hours following a brief cooler spell, though uncertainties in cloud cover or wind shifts could favor nearby 13-14°C outcomes at 19.5% each. New GFS and ECMWF runs, plus MGM bulletins, are due April 4, potentially refining these odds ahead of resolution.
