The Hong Kong Observatory's official minimum temperature reading of exactly 27°C on June 5, 2026, drove the near-certain market consensus. A persistent, humid southwesterly airstream overnight suppressed radiative cooling typical in early summer, keeping overnight lows aligned with the long-term June average of 26–27°C. This outcome matches climatological baselines from the Hong Kong Observatory and NOAA seasonal outlooks projecting above-normal temperatures with minimal day-to-day variability. Only an unforecasted surge in clear skies or a sudden shift to drier northerly flow could have pushed the low below 27°C, but no such development materialized in model consensus or observations.

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.
