Official forecasts from the Hong Kong Observatory indicate a minimum near 26°C on August 31 amid a broad low-pressure trough sustaining showers and thunderstorms, with highs around 30°C and elevated humidity (75-95%) that moderates nighttime cooling. Ensemble guidance shows slight variations in overnight minima between 25-27°C depending on rainfall timing, cloud cover, and shifting winds from southwest to easterly directions. These conditions align with late-summer climatology for the region while the developing El Niño backdrop supports overall warmth. Traders have concentrated probability on 25-27°C outcomes, reflecting model consensus tempered by uncertainty in convective activity and the final observational reading used for market 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.
