Trader consensus on Polymarket prices a tight race between 12°C (34.5%) and 13°C (31.0%) for Istanbul's highest temperature on April 4, driven by the latest ECMWF, GFS, and Turkish State Meteorological Service (MGM) forecast ensembles projecting daytime highs of 11–14°C amid variable cloudiness and scattered morning showers from a weak frontal boundary. Differentiating factors include model spread on afternoon cloud cover persistence—denser overcast in some runs capping peaks at 12°C, while others forecast partial clearing and lighter southwesterly winds (10–15 mph) enabling 13°C—against Istanbul's early-spring baseline of ~14°C. Inherent short-range uncertainty in the city's Black Sea-influenced temperate climate persists; new 12z model runs and evening observations could tip the balance before resolution.

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.
