Hong Kong Observatory forecasts indicate a maximum of 26–30°C for July 27 under mainly cloudy skies with showers and squally thunderstorms that may ease later, driven by southerly winds. These conditions introduce cloud cover and precipitation that limit solar heating and evaporative cooling, keeping daytime peaks near or slightly below the long-term July average of roughly 31–32°C. Recent model consensus and seasonal outlooks for normal-to-above-normal temperatures provide background context, yet short-term dynamics like thunderstorm timing and wind shifts create uncertainty around whether readings settle at 29°C, 30°C, or edge toward 31°C. Traders weigh these variables against historical variability in subtropical summer convection when assessing the closely matched leading outcomes.

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.
