Recent short-term forecast models from agencies including the Hong Kong Observatory point to easterly winds and a strengthening subtropical anticyclone maintaining stable conditions over the region through September 23. These patterns typically produce partly cloudy skies with limited overnight radiational cooling, supporting minimum temperatures near 26–27 °C under dew points around 23–24 °C and moderate humidity. Current observations show daytime highs near 32 °C with gradual moderation expected, consistent with climatological norms for late September amid an ongoing El Niño influence that favors above-average warmth. Model consensus remains tight on this range, though scattered showers could introduce minor variability in the exact low.

This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 23 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.Recent short-term forecast models from agencies including the Hong Kong Observatory point to easterly winds and a strengthening subtropical anticyclone maintaining stable conditions over the region through September 23.
