Official meteorological observations from Shanghai stations confirm a daily maximum of 31°C on August 15, 2026, aligning with subtropical monsoon climatology where August highs typically range 30–35°C amid high humidity and variable cloud cover. Recent model runs from agencies tracking regional pressure patterns and sea-surface temperatures supported this outcome by indicating limited daytime heating due to scattered showers and easterly flow, preventing excursions above the threshold. Trader consensus at 100% reflects real-time data convergence rather than forecast uncertainty. Unlikely revisions could arise only from post-event quality-control adjustments to station records or rare microscale heat anomalies not captured in standard measurements.

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 15 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.
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.Official meteorological observations from Shanghai stations confirm a daily maximum of 31°C on August 15, 2026, aligning with subtropical monsoon climatology where August highs typically range 30–35°C amid high humidity and variable cloud cover.
