Recent short-term forecasts from the Hong Kong Observatory and models indicate persistent summer monsoon conditions with high humidity, scattered showers, and limited overnight radiative cooling, keeping the August 19 minimum near 26–28°C. Variable cloud cover and potential thunderstorm timing create the narrow spread among leading outcomes, as clearer intervals could allow slightly more cooling toward 25°C while sustained moisture and light winds support a 27°C floor. Seasonal guidance for normal-to-above-normal temperatures provides broader context, but day-to-day model consensus on local steering patterns and precipitation will drive final 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
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.
