Recent Hong Kong Observatory forecasts highlight a shift toward generally cloudy conditions with scattered showers and isolated thunderstorms on September 21, driven by weakening high pressure and increased atmospheric moisture, which limits surface heating and caps maximum temperatures near 31°C. This aligns with the closely matched market-implied odds across 28–35°C outcomes, reflecting trader uncertainty over convective development and wind patterns that could either suppress or allow brief sunny intervals to push readings higher. Climatologically, September highs average near 30–31°C, with recent dry, hot spells under subtropical ridges giving way to instability. Updated model runs and official briefings over the next 48 hours will clarify whether rainfall timing or intensity alters the daily maximum.

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.
