**Latest official forecasts from the Hong Kong Observatory position a minimum temperature of 25°C as the leading outcome for September 4.** North to northwest winds of force 4–5, occasionally stronger offshore, combined with the lingering effects of Tropical Cyclone Saudel and a northeast monsoon flow, are expected to bring mainly cloudy skies and a few showers, limiting overnight radiative cooling. Multiple model runs and agency guidance, including Met Office projections, consistently show overnight lows near 25°C with daytime highs of 29–30°C under moderate humidity. This setup aligns closely with the market’s 49.5% implied probability for 25°C and 28.5% for 26°C, while the smaller odds on 24°C reflect residual uncertainty in cloud cover and wind strength. Updated model consensus and any revisions to the HKO outlook ahead of resolution will be the key near-term drivers.

The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Min (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.
