Trader sentiment favors 28°C or higher in Hong Kong on March 26 at 35.5% implied probability, driven primarily by the Hong Kong Observatory's (HKO) latest short-range forecast models projecting highs of 26-28°C under clear skies and light northeasterly winds, following a recent warm spell with daily maxima averaging 25°C over the past week. Climatologically, late March sees average highs near 24°C with standard deviations allowing 30% exceedance of 27°C historically, amplified by urban heat island effects and residual El Niño influences boosting regional temperatures. Ensemble model spread introduces uncertainty, with ECMWF leaning warmer than GFS, positioning 26°C (19%) and 25°C (18%) as strong contenders; traders await HKO's noon update for resolution cues.

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.
