**Recent numerical weather prediction consensus from sources including GFS and regional models points to a maximum temperature of 24–25°C in Istanbul on September 20, supporting the market’s heavy weighting toward 24°C.** Northeasterly (poyraz) winds at moderate strength under partly cloudy to mostly sunny conditions are expected to limit daytime heating while maintaining seasonal norms for mid-September. Current observations on the 19th, with highs near 24–26°C and stable high pressure, reinforce this trajectory, though slight model variations in cloud cover or wind timing could nudge the peak by 1°C. Official monitoring will finalize the daily maximum after the observation period closes, consistent with standard meteorological resolution criteria for city-wide temperature records.

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.
