Trader consensus at 100% implied probability for a 29°C high on August 31 reflects the Hong Kong Observatory’s official daily maximum observation at its headquarters, the resolution standard for this market. Persistent cloud cover, scattered showers, and a broad low-pressure trough over the South China Sea suppressed daytime heating, keeping temperatures below the extreme values seen earlier in August when southerly flow and subsidence produced the record 36.9°C peak. With minimal solar insolation and high humidity limiting surface warming, the observed maximum aligned precisely with 29°C. Realistic challenges to this outcome remain narrow and include any post-day revision to the preliminary HKO reading or use of an alternative station network, though both are improbable given the tight observational window and established resolution criteria.

The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Max (deg. C)" the specified date once information is finalized in the relevant "Daily Extract", available here: https://www.weather.gov.hk/en/cis/climat.htm
This market can not resolve until data for this date has been published.
The resolution source for this market measures temperatures in Celsius to one decimal place (eg, 9.1°C). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is initially published for this market's timeframe will not be considered for this market's resolution.
