Recent forecast models from agencies including the Hong Kong Observatory and global ensembles indicate overnight temperatures stabilizing near 26–27 °C amid persistent cloud cover, light easterly flow, and scattered showers that limit radiational cooling. This setup aligns with climatological September minima around 25–26 °C yet supports the market-implied 67 % probability on 27 °C as the day’s lowest reading. Higher probabilities on 26 °C or below reflect residual model spread in boundary-layer moisture and wind speed, while sub-25 °C outcomes remain discounted absent stronger northerly advection or clearer skies. Updated model runs and official minimum observations expected later today will refine resolution criteria tied to the daily 24-hour minimum.

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.
