Trader consensus on Polymarket tightly clusters implied probabilities around 13–15°C for Istanbul's highest temperature on April 2, driven by the latest GFS and ECMWF model runs forecasting daytime highs near 14°C under partly cloudy skies with northerly winds. Recent observations from late March show persistent cool, rainy conditions with highs in the 8–17°C range, aligning with early spring climatology where April 2 averages hover around 15°C but feature high day-to-day variability from frontal passages over the Marmara Sea. Key differentiators include cloud cover thickness, which could suppress peaks by 1–2°C, versus potential afternoon clearing boosting them; official Turkish State Meteorological Service updates and new model ensembles expected daily will refine this uncertainty ahead of resolution based on airport station measurements.

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.
