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 assigns a 43.5% implied probability to a 15°C high in Istanbul on April 5, reflecting the latest ECMWF and GFS ensemble means projecting mild afternoon peaks of 13–15°C amid northerly winds and partial cloud cover that limit solar heating. Recent model runs over the past 24 hours, including NOAA's GFS 00Z update, have converged on this tight cluster—bolstered by Turkish State Meteorological Service guidance showing similar conditions with possible light sprinkles—shifting odds away from warmer outcomes above 16°C seen in earlier outlooks. Climatological April highs average 16°C, but current synoptic patterns favor cooler anomalies; new 12Z ECMWF/GFS cycles expected today could refine peak timing and cloud trends influencing final resolution based on official Istanbul station measurements.
