Official forecasts from the Hong Kong Observatory indicate a maximum of 32°C on September 10 under the influence of the northeast monsoon, which has slightly cooled morning temperatures while allowing daytime heating to the low 30s amid partly sunny conditions and low precipitation probability. Model consensus and recent observations align with this range, as trade winds limit excessive moisture and cloud build-up that could cap highs below 31°C or push them higher. Trader emphasis on 31–32°C outcomes reflects these stable atmospheric patterns and historical September baselines near 30–31°C, with minor downside risk from localized showers and upside limited by the monsoon's moderating effect ahead of the next forecast update.

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.
