**Trader consensus on the Hong Kong Observatory’s official daily maximum for September 21 centers on 31°C (35.5% implied probability), followed by 30°C (24.5%) and 32°C (22.0%).** The Hong Kong Observatory’s 9-day forecast highlights mainly cloudy skies with a few showers and isolated thunderstorms, plus light northeast winds, which are expected to cap daytime heating despite residual warmth from an upper-air anticyclone. This setup aligns with climatological September norms near 30–31°C while introducing modest cooling from increased cloud cover and moisture. Model guidance shows limited spread, with most runs converging on a peak near 31°C under these conditions. The market’s tight clustering around 30–32°C reflects traders’ assessment of this near-term forecast stability ahead of the Observatory’s final observation.

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
In the event that there is no data for the observation date by 11:59 PM ET on the seventh day following the observation date, this market will resolve to the lowest bracket.
This market will resolve once data for this date has been published on the resolution source, or by 11:59 PM ET on the seventh day following the observation date, whichever comes first.
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 initially published for this market's timeframe will not be considered for this market's resolution.
