A fresh northeast monsoon combined with an upper-level anticyclone is sustaining generally fine, dry conditions across southern China, driving the Hong Kong Observatory forecast for a minimum of 27°C on September 17. Official outlooks consistently project overnight lows in the 27–28°C range under easterly flow of 3–5 Beaufort, with limited cloud cover and low rainfall probability preventing further radiative cooling. Current observations from HKO and regional stations show early-morning readings clustered near 26–27°C, aligning with the market’s dominant 88.5% implied probability for exactly 27°C. Minor deviations to 26°C carry only an 8% consensus, reflecting limited scope for cooler pockets absent any incoming frontal systems or increased humidity. Updated model guidance through the day is expected to confirm whether the minimum settles at or slightly above the forecast threshold.

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.
