Official forecasts from the Hong Kong Observatory highlight persistent cloud cover, showers, and thunderstorms linked to a broad low-pressure trough over the South China Sea, supporting an overnight low near 26°C on August 31. High humidity levels above 75% and light variable winds limit radiative cooling overnight, keeping minimum temperatures clustered around 25–27°C according to multiple model runs. Recent days have shown similar patterns with observed lows of 26–27°C amid frequent rain, aligning closely with the market’s leading outcomes at 26°C (37%), 25°C (24%), and 27°C (23%). Traders appear to weigh the consensus of official guidance against minor forecast spread in exact nighttime minima.

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
This market can not resolve until data for this date has been published.
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.
