Official forecasts from the Hong Kong Observatory point to clear skies, dry conditions, and easterly winds under high pressure for September 19, with a projected range of 27–33°C and very low rain chances. Recent observations show daily maxima near 31–32°C amid stable atmospheric patterns typical for mid-September, supporting market-implied odds favoring 32°C as the most likely peak while assigning lower probability to 33°C. Model consensus and climatological baselines reinforce this narrow band, with traders monitoring any last-minute adjustments to steering flows or humidity that could shift the daily high.

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.
