Persistent active southerly flow and showers associated with a weakening tropical cyclone have kept overnight temperatures stable near seasonal norms for late August in Hong Kong. Official observations from the Hong Kong Observatory show the minimum since midnight reaching 26.3 °C, aligning closely with model consensus and climatological baselines around 25–26 °C. High humidity and cloud cover have limited radiational cooling, supporting the market-implied 97.5 % probability for a 26 °C daily low. A sharper drop below this threshold would require an unexpected surge in northerly winds or clear-sky conditions late in the period, neither of which is indicated in current guidance.

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.
