**Official forecasts from the Hong Kong Observatory and supporting models indicate a minimum temperature of 26–27°C on September 19, driven by a moderating northeast monsoon and persistent anticyclone aloft that maintains generally fine, dry conditions with light easterly winds.** Clear skies overnight support some radiative cooling, yet the overall warm air mass and weak pressure gradients keep lows from dropping further, consistent with historical mid-September baselines around 26°C. Multiple sources project daytime highs of 31–33°C and overnight minima near 25–27°C, with minimal rain risk reinforcing stable temperatures. Traders appear to weigh these consensus signals heavily, though minor model revisions or localized urban heat effects could still shift the exact recorded low before resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 19 Sep '26.
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.**Official forecasts from the Hong Kong Observatory and supporting models indicate a minimum temperature of 26–27°C on September 19, driven by a moderating northeast monsoon and persistent anticyclone aloft that maintains generally fine, dry conditions with light easterly winds.** Clear skies overnight support some radiative cooling, yet the overall warm air mass and weak pressure gradients keep lows from dropping further, consistent with historical mid-September baselines around 26°C.
