**Traders have converged on 27°C as the overwhelming favorite (97% implied probability) for Shanghai’s lowest temperature on August 24, 2026, because multiple official and model forecasts consistently project an overnight minimum in the 26–28°C range.** Current surface observations from Shanghai stations show nighttime readings near 27–28°C under partly cloudy skies with southeasterly flow and high humidity, consistent with late-summer climatology for the region. Numerical weather models maintain this narrow band through the resolution window, with limited spread and no signals for significant advection of cooler air or rapid radiative cooling. A shift to 26°C or 28°C would require an unexpected deviation in the steering pattern or measurement at a specific official station, but the tight consensus across authoritative sources leaves little room for such outcomes before midnight.

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=zspd
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.
