Recent forecasts for Shanghai indicate daytime highs near 30–34°C on August 19, driven by the lingering influence of the western Pacific subtropical high and monsoon moisture. Scattered thundershowers and increased cloud cover, as shown in the latest runs from regional models, are expected to limit peak solar heating and cap temperatures below the seasonal average. These variable conditions—particularly afternoon convection timing and boundary-layer moisture—create the narrow spread across the 28–32°C outcomes that dominate trader consensus. Updated guidance from the China Meteorological Administration and short-range ensembles will clarify intensification or suppression of storms ahead of the daily maximum.

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 19 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.
