Hong Kong Observatory forecasts for May 18 project overnight lows in the 24–25 °C range under mainly cloudy skies with scattered showers and southeast winds, keeping trader consensus tightly split between those two outcomes. Persistent high relative humidity from a lingering low-pressure trough over the northern South China Sea limits nocturnal radiative cooling, preventing sharper drops despite the pre-monsoon transition period. Historical mid-May minimums cluster around these values, reinforced by urban heat-island effects at the official station and shifting southerly airflow that moderates temperature swings. The next HKO bulletin will refine model guidance on cloud cover and wind patterns before resolution.

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.
