Latest official forecasts and numerical weather models, including consensus runs from major global systems, indicate a daily maximum temperature of 31°C for Chengdu on August 29, supporting the market's near-certain implied probability for that exact outcome. Persistent cloudy conditions with light rain or showers have moderated daytime heating while steering patterns have maintained typical late-summer warmth without significant advection of cooler air. Historical climatology for the period shows average highs near 30–33°C, aligning with current observations and model guidance. A realistic challenge would require unexpected heavy precipitation or thicker cloud cover suppressing the peak by several degrees, though recent data releases show limited divergence among authoritative sources.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=zuuu
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.
