Trader consensus on Polymarket overwhelmingly favors 24°C (100%) as Istanbul's highest temperature on May 9, backed by near-complete NOAA observations at Istanbul Airport (LTFM), where hourly METAR reports peaked at 24°C amid mild southerly winds (10-18 km/h), partial cloud cover, and hazy conditions typical of early May's transitional weather. This aligns with ECMWF and GFS model runs from May 8 forecasting highs of 23-25°C, influenced by warm air advection from the Mediterranean and above-average seasonal norms (historical May average ~21°C). With the dataset largely finalized 24 hours post-event, revision risk is minimal; only an improbable official NOAA adjustment to a higher reading from overlooked hourly data could challenge this positioning, pending final timeseries confirmation.

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.
