Recent Hong Kong Observatory forecasts for September 11 project a maximum of 31°C under generally fine, dry conditions with northeast to north winds of 4–5, consistent with northeast monsoon influence suppressing stronger heating. Trader consensus splits closely between 31°C and 32°C because some regional models and analogs show potential for an extra degree if daytime cloud cover stays minimal and solar radiation peaks amid low humidity. Recent observations near 31–32°C on September 9–10 reinforce this narrow range, while low precipitation probabilities limit cooling. Updated model runs and morning observations tomorrow will likely resolve the uncertainty before market close.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 11 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.Recent Hong Kong Observatory forecasts for September 11 project a maximum of 31°C under generally fine, dry conditions with northeast to north winds of 4–5, consistent with northeast monsoon influence suppressing stronger heating.
