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 heavily favors a highest temperature of 15°C at 52.5% implied probability for Istanbul on April 5, 2026, reflecting the latest hourly forecasts from the Turkish State Meteorological Service (MGM) that project peaks of 14–17°C under persistent cloud cover and light showers from a low-pressure system (current 1009 hPa). High humidity (up to 99%) and gusty winds (up to 31 km/h) are suppressing daytime heating, with stadium-specific models like Seyrantepe topping at 14°C around 14:00 local time. Observations from April 4 show struggling highs near 12°C amid rain, cooler than the April climatological average of 16.7°C. Probabilities taper for 16°C (27.5%) and 14°C (13.5%) due to model uncertainty in exact peak timing, with real-time MGM station data through evening poised to resolve the market.
