This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 3 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 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 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.
Recent official forecasts from the Hong Kong Observatory indicate a minimum temperature range of 25–30°C for September 3, driven by persistent northwest monsoon flow and scattered showers that limit nocturnal radiative cooling under mostly cloudy skies. Model outputs and station data show overnight lows stabilizing near 24–25°C amid moderate winds and high humidity, consistent with the market's concentration on 25–26°C outcomes. Tropical cyclone remnants nearby have sustained unsettled conditions without major cooling surges, while historical September baselines for the region favor minima around 25–26°C under similar patterns. Updated model runs and the next HKO briefing will likely refine these implied probabilities ahead of resolution.
