Recent ensemble forecasts from global models such as ECMWF and GFS place Istanbul’s May 18 maximum near 21–22 °C, producing the tight clustering around those two outcomes. A weak high-pressure ridge over the eastern Mediterranean is expected to limit cloud cover while allowing modest southerly flow off the Anatolian plateau, yet a developing sea-breeze circulation from the cooler Black Sea waters could cap afternoon warming by 1–2 °C depending on timing and strength of the onshore gradient. Historical mid-May averages at the Istanbul Airport station sit near 21 °C, so traders are weighing whether the current anomaly will hold or be tempered by increased low-level moisture and reduced insolation. Final resolution will hinge on the official 24-hour maximum recorded at the primary meteorological site.

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.
