Forecast models from global ensembles indicate maximum temperatures in Chengdu on August 18 clustered near 23–24°C, driven by a stable subtropical high-pressure ridge and moderate monsoon moisture that limit afternoon boundary-layer heating. This produces the market-implied probabilities favoring 23°C (68.0%) and 24°C (29.5%), reflecting uncertainty from local Sichuan Basin topography and variable cloud cover or precipitation. Recent observational trends and ensemble runs show suppressed daytime warming relative to August climatological averages of 30–34°C, with key resolution hinging on final peak readings amid ongoing moisture influences.

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 Chengdu Shuangliu 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 Chengdu Shuangliu International Airport Station, available here: https://www.wunderground.com/history/daily/cn/chengdu/ZUUU.
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.
