Hong Kong Observatory's latest 9-day forecast, updated early April 13, projects hot weather with sunny periods and southerly winds on April 15, implying daily highs of 25–30°C amid a persistent warm airstream over southern China. Trader consensus clusters around 29°C (39%) and 30°C or higher (29.5%), narrowly ahead of 28°C (27%), driven by recent observations of 29.7°C maxima on April 13 at the Observatory and up to 30°C at outlying stations like Stanley. Differentiating factors include variable cloud cover reducing solar heating, high relative humidity (65–90%) capping adiabatic warming, and urban heat island effects; model consensus shows potential for 30°C if skies remain mostly clear, but showers loom midweek. Updated twice-daily HKO bulletins and model runs will refine odds before resolution.

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.
