Recent official forecasts from the Hong Kong Observatory indicate a highest temperature of 26–31°C on September 5, driven by lingering effects from Tropical Cyclone Sadler, which is expected to weaken over Guangdong while sustaining increased cloud cover, scattered showers, and moderate southwest winds that limit daytime solar heating and surface warming. Model consensus across sources aligns with highs near 29–31°C, consistent with early-September climatology but tempered by the unsettled pattern rather than clear-sky conditions that could push readings higher. Updated guidance on wind shifts and rainfall timing ahead of the weekend remains the key variable that could refine these probabilities in the final model runs.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 5 Sep '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
In the event that there is no data for the observation date by 11:59 PM ET on the seventh day following the observation date, this market will resolve to the lowest bracket.
This market will resolve once data for this date has been published on the resolution source, or by 11:59 PM ET on the seventh day following the observation date, whichever comes first.
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 official forecasts from the Hong Kong Observatory indicate a highest temperature of 26–31°C on September 5, driven by lingering effects from Tropical Cyclone Sadler, which is expected to weaken over Guangdong while sustaining increased cloud cover, scattered showers, and moderate southwest winds that limit daytime solar heating and surface warming.
