Forecast models from the Hong Kong Observatory and global ensembles indicate a typical mid-August pattern for August 19, with daytime highs most likely reaching 31–32 °C amid scattered showers, thunderstorms, and broken cloud cover that curbs peak solar heating. Seasonal norms place average August maxima near 31 °C, while the current ENSO-neutral backdrop and long-term warming trend support slightly above-normal readings without extreme clear-sky conditions. Traders assign the highest implied probabilities to 31 °C and 32 °C because model runs show limited variability in maximum temperature, hinging mainly on the precise timing and coverage of afternoon convection versus any brief sun breaks. Resolution will depend on the official daily maximum recorded at the Hong Kong Observatory station.

The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Max (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.
