Traders have converged on a 31°C high for Hong Kong on August 15 with near-certainty because official Hong Kong Observatory observations, consistent with post-Typhoon Dolphin cooling and regional model guidance, recorded that exact maximum under partly cloudy conditions with light rain. Seasonal forecasts from the Observatory had projected normal to above-normal August temperatures overall, yet the immediate synoptic pattern after the early-month heatwave produced a modest peak around the long-term climatological average rather than the record 36.9°C seen days earlier. Market-implied odds reflect high confidence in these verified station data, which serve as the resolution benchmark; only an unprecedented post-release correction to the official daily maximum could alter the outcome.

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.
