Recent meteorological forecasts indicate Istanbul will reach daytime maximum temperatures of 25–27°C today, driven by stable high-pressure systems and southerly flow over the region. Official models from the Turkish State Meteorological Service and European Centre for Medium-Range Weather Forecasts show minimal cloud cover and light winds that favor surface heating, consistent with May climatology where highs frequently exceed 24°C. This underpins the market’s 100% implied probability for 25°C or higher. A realistic challenge would require an abrupt shift in steering patterns or unforecasted marine layer intrusion that caps readings below the threshold at official measurement stations by midnight.

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.
