Hong Kong's forecast for August 9 centers on a mainly fine day with maximum temperatures expected near 35–36°C, according to the Hong Kong Observatory's 9-day outlook of 29–36°C and supporting global model guidance. Traders assign the highest probabilities to these thresholds because recent runs show limited cloud cover and light winds allowing strong solar heating, while isolated afternoon showers or thunderstorms could suppress peaks below 37°C. Above-normal seasonal temperatures driven by long-term warming trends and current synoptic patterns add modest upside risk, yet typical August humidity and convective activity create genuine uncertainty around the exact high. Updated model runs and the next HKO briefing will likely refine these market-implied odds.

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.
