Trader consensus on Polymarket prices 13°C at 35% and 12°C at 31% implied probability for Istanbul's highest temperature on April 12, reflecting tight clustering in the latest ECMWF and GFS ensemble forecasts around 12–13°C amid a cool northerly airflow over the Marmara region. Recent light rain and cloudy conditions—such as April 10's observed 7°C high—have suppressed warming, with model spread differentiating outcomes based on afternoon cloud clearance, sea breeze moderation from the Bosphorus, and boundary-layer mixing. Turkish State Meteorological Service (MGM) guidance aligns with this range, below April climatological averages of 16°C due to persistent cold air mass. Final 12z model runs today and hourly observations will sharpen resolution at Istanbul Airport stations.

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.
