Hong Kong Observatory measurements through late May 2026 recorded 215 mm of rainfall, placing the monthly total near the lower end of the typical 220–300 mm climatological range for the period amid scattered convective showers and isolated heavy episodes rather than persistent monsoon systems. This observational baseline, combined with minimal additional accumulation expected or recorded by month-end, underpins the overwhelming trader consensus on the 220–230 mm outcome. The market-implied probability reflects aggregated assessments of official daily extracts and forecast guidance from the Hong Kong Observatory, though final verification could shift slightly if post-28 May data revisions or localized measurement differences alter the precise total.

This market will resolve according to the total precipitation in mm in Hong Kong between May 1 and May 31, 2026, according to the Hong Kong Observatory.
The resolution source for this market will be the Hong Kong Observatory, specifically the "Total Rainfall (mm)" figure for all days in May 2026 under the "Daily Extract" at the https://www.weather.gov.hk/en/cis/climat.htm link once figures are finalized for the specified range.
If the reported data falls exactly between two brackets, this market will resolve to the higher bracket.
If the relevant data is not available by July 7, 2026, 11:59 PM ET, another credible resolution source will be chosen.
The resolution source for this market measures precipitation to 1 decimal place (e.g., 1.5), thus, this is the level of precision that will be used when resolving this market. Any revisions to precipitation recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Hong Kong Observatory measurements through late May 2026 recorded 215 mm of rainfall, placing the monthly total near the lower end of the typical 220–300 mm climatological range for the period amid scattered convective showers and isolated heavy episodes rather than persistent monsoon systems.
