Recent forecasts from agencies including the China Meteorological Administration and numerical models highlight persistent subtropical high pressure combined with scattered thundershowers and increased cloud cover as the main drivers keeping Shanghai's August 18 high temperature centered near 30–32°C. These conditions, typical for mid-August in the Yangtze River Delta, limit daytime heating while elevated humidity and weak steering flows reduce the chance of stronger warming or rapid cooling. Historical climatology shows average highs of 31–33°C this week of the year, aligning with current model runs that show only modest day-to-day variability. Updated guidance expected within 24–48 hours could refine land-sea breeze effects and precipitation timing, directly influencing the resolution thresholds around the leading 31°C and 30°C outcomes.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Shanghai Pudong International Airport Station in degrees Celsius on 18 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest 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.
