Hong Kong Observatory's latest 9-day forecast, updated April 1, projects a 24–29°C temperature range for April 3 under mainly cloudy skies with sunny intervals, a few showers, and isolated squally thunderstorms later, driven by shifting southerly winds force 4–5 amid persistent troughs of low pressure. This broad range fuels trader uncertainty, yielding closely matched market-implied probabilities around 26°C (28%), 27°C (27%), and 28°C (25.5%), as cloud cover and afternoon precipitation could suppress peaks despite warmer southerly airflow and seasonal above-normal temperature outlook. Differentiating factors include timing of sunny breaks for solar heating, thunderstorm onset capping highs, and urban heat island effects; daily HKO updates and model ensembles will sharpen guidance ahead of resolution based on official observatory measurements.

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.
