Trader consensus reflects high uncertainty in Shanghai’s July 18 minimum temperature, with 29 °C and 23 °C-or-below outcomes nearly tied near 39 % and 38 % implied probability. Typical mid-July overnight lows average 25–27 °C under humid subtropical conditions, but recent model runs show potential for enhanced nocturnal cooling if clearer skies develop after daytime convection, versus warmer minima near 28–29 °C if persistent cloud cover or scattered thunderstorms—already indicated in extended forecasts—limit radiative heat loss. Shanghai’s urban heat island and high humidity further compress the diurnal range, keeping outcomes clustered between 25–29 °C while rendering sub-24 °C values sensitive to any late-model shifts in precipitation timing or wind. Updated National Meteorological Center guidance expected within 24 hours will likely narrow the distribution ahead of market resolution.

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 18 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 reflects high uncertainty in Shanghai’s July 18 minimum temperature, with 29 °C and 23 °C-or-below outcomes nearly tied near 39 % and 38 % implied probability.
