Official forecasts from the Hong Kong Observatory indicate a minimum temperature range of 25–29°C or 26–30°C for September 4, driven by northwest to northwesterly winds of 4–5 on the Beaufort scale associated with the weakening tropical cyclone Sa Del and northeast monsoon influence. These conditions promote moderate overnight cooling under mostly cloudy skies with scattered showers, limiting radiative heat loss while maintaining high humidity levels of 70–95%. Recent model consensus and observational trends from the past 48 hours show overnight lows stabilizing near 25°C, consistent with climatological September baselines, though minor shifts in wind strength or precipitation could adjust the realized minimum. Market-implied odds favor 25°C as the mode, reflecting trader assessment of these atmospheric dynamics ahead of final resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 4 Sep '26.
The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Min (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 minimum temperature range of 25–29°C or 26–30°C for September 4, driven by northwest to northwesterly winds of 4–5 on the Beaufort scale associated with the weakening tropical cyclone Sa Del and northeast monsoon influence.
