**Official forecasts from the Hong Kong Observatory point to a maximum of 31°C on September 22 amid a shift from recent clear, high-pressure conditions to increased cloud cover and scattered showers.** On September 20, surface observations reached 33°C+ under dry easterly flow and subsidence, but models indicate moderating influences by midweek, including higher humidity (65–95%) and reduced insolation from convective clouds. This creates tight uncertainty between 29–31°C outcomes, as the exact timing and coverage of showers—driven by a weakening anticyclone and possible trough influence—will determine peak heating. Historical late-September normals hover near 30–31°C, with traders weighing model consensus on boundary-layer mixing and diurnal temperature ranges against the risk of brief clearing allowing brief spikes. Updated HKO briefings and ensemble runs over the next 48 hours remain key resolution catalysts.

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.
