Polymarket market analysis
Will Hong Kong have between 140-150mm of precipitation in April?
Summary
This market will resolve according to the total precipitation in mm in Hong Kong between April 1 and April 30, 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 April 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 June 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.
