Trader consensus on Polymarket reflects tight clustering around 12–14°C for Istanbul's highest temperature on April 17, driven by short-range forecast models like ECMWF and GFS showing ensemble means near 13°C amid persistent northerly winds from a lingering upper-level trough over the Black Sea. Recent cold air advection from the Balkans, noted in Turkish State Meteorological Service (MGM) updates, has kept daytime highs 3–5°C below April climatological norms of 16–17°C, with partial cloud cover further capping solar heating. Differentiating factors include model disagreements on afternoon clearing and boundary-layer mixing, yielding a 2–3°C spread; final observational data from Florya station today could tip outcomes 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.
