Recent forecasts from multiple meteorological sources indicate a minimum temperature near 19–21°C overnight in Istanbul on August 28, 2026, driven by northerly winds, increased cloud cover, and scattered showers that limit radiative cooling. Model consensus shows daytime highs around 26°C followed by gradual nighttime decline under moderate humidity levels of 60–80%, consistent with late-summer climatology for the region. Updated guidance issued August 27 reinforces this range, with limited model spread supporting the strong market weighting toward 18°C as the most probable recorded low. Upcoming hourly observations through dawn will determine final resolution against the precise measurement criteria.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Istanbul Airport in degrees Celsius on 28 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.Recent forecasts from multiple meteorological sources indicate a minimum temperature near 19–21°C overnight in Istanbul on August 28, 2026, driven by northerly winds, increased cloud cover, and scattered showers that limit radiative cooling.
