Latest numerical weather prediction models project a daytime high near 25–26°C for Istanbul on September 21 under mostly clear skies and light northeasterly winds. This outlook stems from a stable high-pressure ridge suppressing cloud formation and limiting mixing, consistent with late-September climatology where average highs reach about 23°C. Minor model spread in boundary-layer moisture or wind strength could shift the peak by 1–2°C, keeping probabilities distributed across the 22–29°C range. Updated runs from agencies such as the Turkish State Meteorological Service and ECMWF over the next 24 hours will provide the clearest signals ahead of market resolution.

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.
