Forecast consensus from multiple models points to clear skies and moderate northeasterly winds over Istanbul on August 27, supporting nighttime radiative cooling that favors a minimum near 21–22°C. Recent trends show highs declining from 32°C earlier in the week to around 29–30°C, with stable high pressure limiting cloud cover and moisture that could otherwise moderate overnight lows. Key variables separating the tightly matched 21°C and 22°C outcomes include subtle differences in boundary-layer mixing, exact wind speeds at the measurement site, and potential urban heat influences. Updated runs from agencies like the Turkish Meteorological Service or ECMWF could shift probabilities if they revise the low by even 1°C before resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 27 Aug '26.
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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.Forecast consensus from multiple models points to clear skies and moderate northeasterly winds over Istanbul on August 27, supporting nighttime radiative cooling that favors a minimum near 21–22°C.
