Forecast consensus from multiple meteorological models points to a high of 25–26°C in Istanbul on September 21, driven by mostly sunny to partly cloudy conditions, light northeasterly winds, and minimal cloud cover that allows efficient daytime heating. This aligns with late-September climatology for the region, where highs typically range 24–27°C under stable high-pressure influence ahead of an approaching frontal system expected to bring cooler air and rain by September 22. The market’s strong 63.5% implied probability on 25°C and 30% on 24°C reflects traders’ assessment of these stable atmospheric patterns and limited model spread, with lower-probability outcomes tied to potential minor forecast revisions from updated runs or localized variations in urban heat effects.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=LTFM
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
