Persistent low-pressure trough over the northern South China Sea combined with effects from Tropical Storm Narra are driving increased cloud cover, showers, and squally thunderstorms across Hong Kong on August 25, limiting solar insolation and capping daytime maxima. Official Hong Kong Observatory guidance points to a 26–30°C range under south to southwest winds of 4–5, occasionally gustier offshore, with humidity 75–95%. These conditions favor lower outcomes near 29–30°C, yet trader sentiment clusters around 30–32°C amid model spread on rainfall timing and any brief clear intervals that could allow brief warming. High baseline moisture and onshore flow further suppress extremes relative to climatology. Updated model runs and HKO briefings ahead of the 25th will refine resolution probabilities.

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.
