Current forecasts for Istanbul on September 4 show overnight lows clustered near 21–22°C under clear skies, light northeasterly winds, and stable high pressure near 1015–1017 hPa, with no precipitation expected. This setup limits radiative cooling while the urban heat island and proximity to the Sea of Marmara moderate temperatures above the September climatological minimum of 17°C. Model consensus across sources supports this range, yet small divergences arise from variations in boundary-layer mixing and exact wind speeds, which can shift the observed low by 1–2°C. The tightly matched market odds reflect this genuine uncertainty in the final minimum reading before resolution.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
