Hong Kong Observatory's latest 9-day forecast, updated April 30 at 23:20 HKT, projects a May 1 temperature range of 22–25°C under mainly cloudy conditions with 70–90% humidity, east-northeast winds force 4, and isolated morning/night rain patches, centering trader consensus around a 22°C low at 44.5% implied probability versus 21°C at 39%. High humidity and persistent cloud cover—driven by a Guangdong cloud band—limit nocturnal radiative cooling, while moderate winds mix the boundary layer, but slight clearing or trough-induced cooling ahead of the weekend cold front could dip to 21°C. Model consensus reflects this tight uncertainty, with historical May lows averaging 23°C amid normal-to-above-normal seasonal temperatures; watch HKO's next local forecast update for refinements.

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.
