Hong Kong Observatory's latest 9-day forecast, updated at 16:30 HKT on April 11, projects daytime highs of 26–29°C on April 12 under a southerly airstream delivering hot conditions with sunny intervals amid mainly cloudy skies and isolated showers, driving trader consensus toward 28°C as the leading outcome at 45% implied probability. This range reflects model consensus for above-normal April temperatures in a seasonally warm pattern, with south winds force 4–5 enhancing heat advection while high humidity (70–90%) and low precipitation risk temper extremes. Recent soil temperatures around 26°C and sea surface at 24°C support potential for peaks near 29°C, though cloud cover introduces uncertainty; official HKO observations will resolve the market tomorrow.

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.
