Current forecast guidance from the Hong Kong Observatory and global models indicates overnight lows of 26–27 °C on September 7 under partly cloudy skies with scattered showers and light variable winds, following the passage of Tropical Storm Saudel. These conditions align with seasonal norms for early September, when typical minimums range 25–27 °C amid high humidity and weak steering flow before the northeast monsoon strengthens later in the week. Ensemble consistency across ECMWF, GFS, and regional runs supports this narrow band, with limited cooling potential from cloud cover and moisture rather than any sharp frontal boundary. Traders appear to weigh the balance between slightly above-normal monthly temperature outlooks and short-term model consensus, with fresh HKO updates expected to refine overnight readings ahead of resolution.

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.
