Latest ECMWF and GFS ensemble forecasts project Istanbul's highest temperature on April 7 between 12-15°C, fueling trader consensus with 27.5% implied odds on 14°C and 26% on 13°C amid tight clustering across nearby outcomes. This reflects persistent northerly winds advecting cooler continental air over the Marmara region, coupled with partly cloudy conditions that curb insolation and peak heating. Differentiating factors include model divergences on boundary layer mixing, sea breeze strength from the Black Sea and Marmara Sea, and exact timing of any diurnal clearing—subtle shifts yielding 1°C variances. Historical early-April highs average 14°C, consistent with current guidance. Traders await Turkish State Meteorological Service updates and new 00Z/12Z model runs by April 6 for refinement.

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.
