Current meteorological forecasts for Hong Kong point to elevated overnight minimum temperatures on May 21, with ensemble guidance from the Hong Kong Observatory favoring values near or above 29°C due to southerly warm-air advection and reduced radiative cooling under partly cloudy skies. This positioning reflects a departure from late-May climatological averages of 24–25°C, as recent model runs show limited influence from cooler northerly flows or significant precipitation that could enhance nocturnal temperature drops. Traders are watching for updates in the next 48 hours from regional numerical weather prediction systems, which could shift probabilities if steering patterns or humidity levels change.

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 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.
