Recent official forecasts from the Hong Kong Observatory indicate a minimum temperature of 27°C on September 9 under easterly to northeasterly flow of 4–5 on the Beaufort scale, with partly cloudy skies and scattered showers. This aligns with prevailing high-pressure ridging and typical early-September climatology, where overnight radiative cooling is limited by humidity levels near 60–90% and minimal frontal influence. Ensemble guidance shows low potential for further cooling below 26°C absent stronger northerly advection or clearer skies, while the 27–28°C range dominates trader positioning given the narrow spread in short-range model outputs and absence of tropical cyclone impacts. Updated runs through early September continue to support these thresholds ahead of the resolution window.

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.
