Trader consensus on Polymarket assigns a 100% implied probability to 17°C as Istanbul's highest temperature today, driven by the Turkish State Meteorological Service's (MGM) latest hourly forecast—updated at 11:50 local time—showing peaks of 17°C from noon to 3 p.m. under clear skies, transitioning to 18°C briefly before cooling, with current airport-area observations hovering at 15-17°C amid light winds (10 km/h) and 50% humidity that cap warming. This aligns with a recent cool spell, including yesterday's 15°C maximum, and model convergence from ECMWF/GFS analogs indicating limited solar heating potential. Realistic challenges include prolonged clear conditions or a wind shift boosting afternoon temps to 18°C, though low sun angles and stable air masses make this unlikely; monitor MGM updates and NOAA Istanbul Airport (LTFM) readings for final 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.
