Recent forecasts for Hong Kong on August 2 point to showery conditions with daytime maxima around 28°C, aligning with the tight clustering of market-implied odds between 26°C and 29°C. Persistent cloud cover and scattered thunderstorms typical of the summer monsoon trough limit solar heating and suppress peak temperatures compared to clearer summer days. Official seasonal guidance from the Hong Kong Observatory, updated July 30, calls for normal to above-normal temperatures overall for August amid ongoing climate warming trends, yet short-term model runs emphasize rainfall that caps highs near the lower end of August climatology. Traders appear to weigh uncertainty in exact rain timing and intensity—factors that could shift the daily maximum by 1–2°C—while discounting rarer scenarios of stronger heating or extreme downpours. Updated numerical weather predictions and any new HKO briefings in the coming days will likely refine these odds further.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 2 Aug '26.
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.Recent forecasts for Hong Kong on August 2 point to showery conditions with daytime maxima around 28°C, aligning with the tight clustering of market-implied odds between 26°C and 29°C.
