**Forecast models from agencies tracking Shanghai’s subtropical monsoon climate show the overnight low stabilizing near 27°C on August 29, 2026.** Persistent warm, humid air under the influence of the Northwest Pacific subtropical high, combined with light easterly winds and scattered showers, has kept minimum temperatures in the 27–28°C range for recent days, consistent with late-summer climatology. Official guidance and ensemble runs converge on this value, giving traders high confidence in the 27°C outcome at 94.5% implied probability. A sharper-than-expected nocturnal cooling from heavier rainfall or an unforecast wind shift could push readings toward 26°C, but current conditions and model agreement make such a deviation unlikely 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=zspd
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.
