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 Wuhan Tianhe 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 Wuhan Tianhe International Airport Station, available here: https://www.wunderground.com/history/daily/cn/wuhan/ZHHH. 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.
Recent numerical weather models from global and regional forecasting centers indicate a peak temperature near 35°C in Wuhan on August 19, driven by persistent subtropical high pressure and limited cloud cover that favors daytime heating in the Yangtze River basin. Ensemble guidance shows modest spread, with potential for isolated thunderstorms to cap highs at 34°C or allow brief clearing that pushes readings to 36°C, aligning with the market-implied probabilities clustering around these values. Historical August climatology for the city features mean daily maxima of 32–34°C, providing context for why traders assign lower weight to outcomes below 34°C or above 37°C absent major shifts in steering patterns. Updated model runs and official China Meteorological Administration briefings in the next 48 hours represent the key upcoming catalysts that could refine these odds.
