This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 8 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 Hong Kong Observatory forecasts point to a 27–33°C range on September 8 under mainly fine, very hot conditions with light winds, establishing 27°C as the market favorite at 56.5% implied probability. Recent observations show overnight lows near 27°C amid a persistent warm, humid airmass with dew points in the mid-20s. Ensemble models display modest spread, with some projecting 25–26°C minima if scattered showers or slightly stronger easterly flow develop overnight, supporting the secondary 26°C (21.5%) and 28°C (18.5%) outcomes. The approaching northeast monsoon later in the week has yet to strongly influence tomorrow’s boundary layer, keeping temperatures elevated relative to seasonal September baselines. Updated HKO guidance and new model runs ahead of the overnight period remain the key near-term catalysts for any shift in trader positioning.
