The Hong Kong Observatory's official forecast for September 8 calls for a minimum temperature of 27°C under mainly fine skies and light east to northeast winds of 2-3, consistent with current overnight observations near 27-28°C and the strengthening influence of the northeast monsoon. This aligns with early-September climatology, where typical lows hover around 25-27°C amid high humidity and limited nocturnal cooling from urban heat island effects. Trader consensus at 93.5% for 27°C reflects the narrow uncertainty band in numerical weather models and the absence of significant cloud cover or precipitation expected to alter radiative cooling overnight. A realistic shift could occur only if unforecasted showers develop or if model runs revise the steering flow, potentially nudging the minimum by 1°C either way before resolution.

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.
