Official measurements from the Hong Kong Observatory recorded a daily maximum of exactly 27°C on May 15, 2026, driving near-certain trader consensus on that outcome. This aligns with mid-May subtropical climatology, where persistent high pressure from the South China Sea and strengthening southwest monsoon flow typically produce afternoon highs in the 26–29°C range at the primary urban station, consistent with historical records showing median maxima rising toward 28°C during this transition period. Model guidance and observational trends prior to the date supported stable conditions without significant diurnal heating spikes. A realistic challenge to this resolution would require an unforeseen post-event data revision or station-specific anomaly, though such adjustments are rare once preliminary readings are confirmed and archived.

This market will resolve to the temperature range that contains the highest temperature recorded by the Hong Kong Observatory in degrees Celsius on 15 May '26.
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 to "Yes" until data for this date has been finalized.
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 finalized for this market's timeframe will not be considered for this market's resolution.Official measurements from the Hong Kong Observatory recorded a daily maximum of exactly 27°C on May 15, 2026, driving near-certain trader consensus on that outcome.
