Official forecasts from the Hong Kong Observatory indicate a high of 31°C on September 17 under persistent northeast monsoon flow and high-pressure subsidence, producing clear skies, low humidity, and minimal rain chances. These stable atmospheric conditions, with easterly winds at 4–5 on the Beaufort scale, favor temperatures clustering near the 30–31°C range observed in recent days. Model consensus shows little day-to-day variability, though slight warming could push readings to 32°C if subsidence strengthens. Traders price 31°C highest at 39.5% implied probability, reflecting alignment with the authoritative 27–31°C forecast range and limited upside potential before resolution tomorrow.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 17 Sep '26.
The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Max (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 indicate a high of 31°C on September 17 under persistent northeast monsoon flow and high-pressure subsidence, producing clear skies, low humidity, and minimal rain chances.
