Hong Kong Observatory's precise air temperature observations, updated hourly on April 1, 2026, recorded a peak of 27°C at the Observatory headquarters around noon, with matching readings at stations like Tai Mei Tuk, propelling trader consensus to 100% implied probability for that outcome amid real-money positioning. Afternoon temperatures eased to 25-26°C under moderate easterly airflow and fine skies, aligning with pre-event model consensus forecasting 27-28°C in a season of normal to above-normal heat per HKO's April-June outlook for this exceptionally warm 2026. This positioning reflects verified meteorological data from calibrated sensors, though rare quality-control revisions uncovering higher remote-station readings could theoretically challenge it before final daily bulletin confirmation.

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.
