**Official Hong Kong Observatory forecasts position 27°C as the most likely overnight minimum for September 8, 2026, with a predicted range of 27–33°C under generally fair to partly cloudy skies and light easterly to northeasterly winds.** This aligns with the market’s leading 63.5% implied probability for 27°C, as recent HKO guidance issued on September 7 emphasizes weak pressure gradients and limited cloud cover that typically allow radiative cooling to reach the seasonal baseline minimum near 27°C. Model outputs and nearby observations show overnight lows stabilizing around 26–28°C, with urban heat effects and light winds reducing the chance of deeper cooling to 25°C or below (combined market share under 6%). A strengthening northeast monsoon later in the week and a distant low-pressure area offer little near-term disruption, supporting trader consensus around the current forecast while leaving modest room for 26°C or 28°C depending on final model runs and localized conditions.

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 position 27°C as the most likely overnight minimum for September 8, 2026, with a predicted range of 27–33°C under generally fair to partly cloudy skies and light easterly to northeasterly winds.**
