The Hong Kong Observatory's 9-day forecast, updated at 11:30 HKT on May 1, projects a lowest temperature of 23°C on May 3 amid mainly cloudy conditions, showers, and squally thunderstorms as a cold front from central China crosses southern China, shifting winds from southerly to northerly force 4-5 later in the day. This aligns with the market's leading 23°C outcome at 22.5% implied probability, while nearby 21–24°C options reflect uncertainty in nighttime radiative cooling suppressed by high humidity (70–95%) and cloud cover versus potential post-frontal drying. Global models like GFS show slightly lower lows around 21°C in some runs, but HKO's multi-model consensus favors 23°C given May's typical urban heat island effect and seasonal normal-to-above-normal temperatures; watch for the 16:30 HKT update and May 2 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 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.
