Official forecasts from the Hong Kong Observatory indicate a daytime maximum near 32°C on August 25 under a southerly airstream, with scattered showers, thunderstorms, and periods of cloud cover expected to limit solar heating and peak temperatures. Recent observations show surface readings in the 29–31°C range by early afternoon alongside rainfall in multiple districts, consistent with convective suppression of further warming. Market-implied probabilities favoring 31°C over higher values reflect trader assessment of these moisture-driven cooling effects and historical August patterns where persistent rain often caps maxima below model peaks. Updated radar and station data through the afternoon will refine the final recorded high at the Observatory.

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.
