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 Chongqing Jiangbei International Airport Station in degrees Celsius on 21 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 Chongqing Jiangbei International Airport Station, available here: https://www.wunderground.com/history/daily/cn/chongqing/ZUCK. 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.
Latest forecast guidance from meteorological agencies points to a daily maximum of 33–34°C in Chongqing on August 21, reflecting the primary driver behind current market-implied odds. Persistent subtropical high pressure over the region, combined with the heat-trapping effects of the Sichuan Basin topography and high humidity that limits overnight radiative cooling, supports this range under typical late-summer conditions. Official model consensus, including runs highlighting 33–34°C highs, aligns with climatological baselines for mid-to-late August, when averages hover near 32–34°C. Traders appear to weigh the slight edge toward 33°C against potential model variability in timing of any cloud cover or weak frontal influences. Updated regional forecasts and observational data ahead of the date remain the key near-term catalysts for any shifts in these probabilities.
