Recent forecasts indicate persistent cloud cover, showers, and thunderstorms around August 20 will moderate overnight radiative cooling in Hong Kong’s subtropical monsoon climate, keeping minimum temperatures near the seasonal average of 26–28°C. Numerical weather prediction models show slight variations in timing and intensity of convective activity, which can shift the daily low by 1–2°C depending on wind patterns and humidity levels. Trader consensus clusters tightly on 28°C and 29°C because current ensemble guidance from agencies like the Hong Kong Observatory supports these values, while lower or higher outcomes remain possible if rainfall is heavier or lighter than expected before the market resolves.

This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 20 Aug '26.
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.Recent forecasts indicate persistent cloud cover, showers, and thunderstorms around August 20 will moderate overnight radiative cooling in Hong Kong’s subtropical monsoon climate, keeping minimum temperatures near the seasonal average of 26–28°C.
