Recent numerical weather prediction models from sources like ECMWF and GFS indicate Istanbul's June 23 maximum will likely fall between 25–27°C, driven by moderate high-pressure influence, light northerly winds across the Bosphorus, and limited cloud cover allowing typical early-summer insolation. Sea-breeze effects from the Marmara and Black Seas may cap afternoon peaks near 26°C while suppressing stronger warming. Ensemble spreads reflect genuine uncertainty from minor shifts in steering patterns or boundary-layer moisture, keeping 25°C, 26°C, and 27°C outcomes closely matched in trader pricing. Updated model runs and official Turkish State Meteorological Service briefings over the next 48 hours will refine these thresholds ahead of market resolution.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 23 Jun '26.
The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, 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 until the first data point for the following date has been published on the resolution source.
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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Recent numerical weather prediction models from sources like ECMWF and GFS indicate Istanbul's June 23 maximum will likely fall between 25–27°C, driven by moderate high-pressure influence, light northerly winds across the Bosphorus, and limited cloud cover allowing typical early-summer insolation.
