Trader consensus clusters tightly around a 27–29°C minimum for Shanghai on July 25, reflecting model spread in nocturnal cooling under the East Asian summer monsoon. Recent ECMWF and GFS runs show variable cloud cover and scattered showers that limit radiative heat loss after daytime highs near 33–35°C, while humidity above 80% and light winds reduce the typical diurnal range. Official guidance from the China Meteorological Administration emphasizes uncertainty in timing of any frontal passage or tropical moisture surge, which could drop the overnight low by 1–2°C or hold it near 28°C. Updated model runs and local observations through July 24 will be key for resolving these thresholds.

This market will resolve to the temperature range that contains the lowest temperature recorded at the Shanghai Pudong International Airport Station in degrees Celsius on 25 Jul '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the Shanghai Pudong International Airport Station, available here: https://www.wunderground.com/history/daily/cn/shanghai/ZSPD.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.Trader consensus clusters tightly around a 27–29°C minimum for Shanghai on July 25, reflecting model spread in nocturnal cooling under the East Asian summer monsoon.
