Ensemble forecasts from the European Centre for Medium-Range Weather Forecasts and Global Forecast System position Istanbul’s May 18 maximum near the mid-May climatological average of 20–22 °C under moderate southeasterly flow and limited moisture. This atmospheric setup, without notable warm advection or blocking patterns, underpins trader consensus favoring 21 °C as the leading outcome while spreading probability across 20–22 °C bins. Sea-breeze moderation along the Bosphorus and variable cloud cover introduce minor model spread, keeping the chance of readings reaching 23 °C or higher relatively low. Final resolution will hinge on official observations from Istanbul Airport once the day concludes, with historical Turkish State Meteorological Service data confirming similar spring conditions rarely exceed this narrow range absent stronger synoptic forcing.

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.
