Recent official forecasts from the Turkish State Meteorological Service and international models indicate a peak temperature of 24°C for Istanbul on September 18, 2026, under partly cloudy skies with moderate northeast winds of 15–20 km/h. This positioning reflects the consensus across GFS and ECMWF runs showing limited daytime heating due to persistent cloud cover and stable high pressure, consistent with late-September climatology where daily maxima average near 23–25°C. Current observations around midday reached 22–23°C with dew points supporting modest further rises, while the low probability of 25°C or higher stems from the absence of stronger southerly flow or clear-sky amplification. Updated model guidance later today will refine the final maximum before 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.
