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 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.Latest short-range forecast ensembles from ECMWF and GFS models show Istanbul's maximum 2-meter temperature tightly clustered at 12–14°C today, driving the near-even split in trader odds with 12°C and 13°C edging ahead at 33.5% and 31.0%. Persistent northerly winds from a lingering low-pressure system over the Black Sea are suppressing highs below April climatological norms of around 16°C, while variable cloud cover introduces uncertainty in peak solar insolation. Differentiating factors include subtle model divergences on boundary-layer mixing and afternoon clearing potential; official Turkish State Meteorological Service (MGM) hourly observations from central stations will provide resolution criteria, with any unexpected sunshine burst able to tip toward 14°C.
