Hong Kong Observatory rain gauge data confirms 160.4mm of accumulated rainfall through April 29, locking in trader consensus at 98.4% for the 160-170mm outcome as only the final day remains. Late April showers, building on early heavy downpours like 45.1mm on April 5, propelled totals above the historical monthly average of around 150mm amid the rainy season onset. Current forecasts indicate stable fine weather with minimal precipitation expected on April 30, minimizing upside risk. Realistic challenges include an unforeseen thunderstorm or convective burst delivering over 9.6mm, potentially tipping into 170-180mm or higher bins, though model consensus shows low rain probabilities.

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. Any revisions to precipitation recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
