Latest meteorological forecasts for Istanbul on September 18 point to an afternoon peak of 23–24°C under partly cloudy skies and moderate northeast winds, driving the tight 52%–43% market split between those outcomes. Regional pressure patterns and Sea of Marmara surface temperatures are moderating daytime heating while limiting stronger solar input from variable cloud cover, keeping values near the September climatological average of roughly 24°C. Model consensus shows minimal risk of exceeding 25°C or falling to 22°C, with any brief showers exerting only localized cooling effects. Traders are weighing the final official station reading against these variables as the day progresses.

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.
