This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 16 May '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.Current ensemble forecasts from GFS and ECMWF models, aggregated by services like TimeandDate, project a high temperature of around 24°C (75°F) in Istanbul on May 16, up from 17°C the prior day, driven by a shift to high-pressure ridging and mostly sunny skies following recent drizzle. This mild warming aligns with Istanbul's Mediterranean climate, where mid-May averages hover at 21°C based on long-term observations from the official Florya station, with sea breezes from the Bosphorus often capping peaks. The Turkish State Meteorological Service (MGM) 5-day outlook supports this consensus, though 48-hour updates could adjust for cloud cover or northerly winds. Trader sentiment reflects this stability, with low precipitation risk (20%) and historical rarity of extremes this early in spring. Watch MGM briefings tomorrow for refined guidance ahead of resolution via airport measurements.
