Official observations from the Hong Kong Observatory established a daily maximum temperature of 27°C on May 15, 2026, under persistent overcast skies, 83–89% relative humidity, and widespread thundery showers tied to a low-pressure trough over the South China Sea. This verified station reading, consistent with mid-May subtropical climatology where daytime highs typically range 26–29°C, anchors the market’s near-certain 27°C outcome as traders incorporate the precise resolution data rather than forecasts. Realistic challenges to this result would require abrupt sky clearance, sharply reduced humidity, and stronger solar insolation allowing prolonged radiative warming, though such conditions were absent amid the active trough and elevated moisture.

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.
