Strong El Niño conditions, with Niño 3.4 SST anomalies recently exceeding +2.0°C and forecasts for a very strong event through late 2026, represent the dominant driver shaping trader sentiment for Hong Kong's August rainfall. This phase of ENSO typically weakens the East Asian summer monsoon while altering tropical cyclone tracks and intensity, introducing substantial variability around the long-term August mean of roughly 450 mm. Official outlooks emphasize uncertainty in short-term monsoon bursts and any late-month typhoon influences, which could push totals into the leading 700 mm+ bin or keep them near the 425–550 mm cluster where multiple outcomes cluster around 24–25% implied probability. Updated seasonal model runs and early-month observations will provide key signals for resolution thresholds.

If the reported data falls exactly between two brackets, this market will resolve to the higher bracket.
The resolution source for this market will be the Hong Kong Observatory, specifically the "Total Rainfall (mm)" figure for all days in August 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 relevant data is not available by November 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.
