**Northeast monsoon flow is the dominant driver moderating Hong Kong temperatures ahead of September 11, 2026.** Official Hong Kong Observatory guidance forecasts a maximum of 31°C under mainly fine, dry daytime conditions with north-to-northeast winds of force 4–5, following the recent arrival of cooler, drier air from the north that has already lowered morning readings. Historical September normals place the daily maximum near 30.8°C, and current model consensus shows limited potential for strong daytime heating or convective suppression that could push values to 33°C or above. Trader emphasis on 31–32°C outcomes aligns with this pattern of modest warming under stable high pressure and low precipitation risk, while probabilities drop sharply outside 29–33°C given the established steering flow and absence of tropical moisture or clear-sky amplification in the latest updates.

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.**Northeast monsoon flow is the dominant driver moderating Hong Kong temperatures ahead of September 11, 2026.** Official Hong Kong Observatory guidance forecasts a maximum of 31°C under mainly fine, dry daytime conditions with north-to-northeast winds of force 4–5, following the recent arrival of cooler, drier air from the north that has already lowered morning readings.
