Recent forecasts from multiple models indicate Shanghai's overnight low on August 31 will likely settle between 26–28°C, aligning with the market's leading outcomes amid persistent humidity and scattered showers. In Shanghai's humid subtropical climate, typical late-August minima hover near 25–26°C; current conditions with southeasterly winds, 70–90% humidity, and cloud cover from incoming systems are suppressing radiative cooling and keeping temperatures elevated relative to drier analogs. Official guidance shows consensus around 26–27°C lows, with minor model spread tied to exact rainfall timing and wind shifts that could nudge readings by 1–2°C. Updated numerical weather predictions and local observations over the next 48 hours will refine these probabilities ahead of resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Shanghai Pudong International Airport Station in degrees Celsius on 31 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=zspd
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.
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 models indicate Shanghai's overnight low on August 31 will likely settle between 26–28°C, aligning with the market's leading outcomes amid persistent humidity and scattered showers.
