Northeast monsoon influence over southern China is the dominant factor shaping trader views, with official Hong Kong Observatory guidance pointing to daytime temperatures of 26–32°C on September 10 amid partly sunny skies, a few showers, and drier conditions. Recent observations show highs of 31–32.7°C through September 8–9 before the cooler northeasterly flow arrives, while model consensus and historical September patterns support a most probable peak near 31°C. Lower odds on 29°C or below reflect limited cooling potential during peak heating hours, and slim chances above 33°C align with the stabilizing monsoon and typical diurnal ranges under these conditions. Updated HKO briefings and regional model runs remain the key near-term catalysts.

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.
