Persistent high humidity and minimal nocturnal radiative cooling kept overnight temperatures elevated across Hong Kong on August 13, with Hong Kong Observatory surface readings holding between 29–32°C through the evening hours. This midsummer pattern, driven by warm sea-surface temperatures around 27°C and light southerly flow, produced an official daily minimum of 30°C at the primary monitoring site. Traders have converged on this outcome at 100% implied probability because it aligns directly with verified HKO data rather than model forecasts. Only an unreported station anomaly or post-event data revision could alter resolution, both of which remain statistically improbable given the observatory’s standardized protocols and real-time quality controls.

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.
