Persistent cloud cover, easterly winds, and scattered thunderstorms are moderating peak heating in Hong Kong today, keeping maximum temperatures near the long-term September average of roughly 30°C. Current midday readings hover around 28–29°C with high humidity and limited sunshine, while forecast models show modest disagreement on afternoon clearing that could allow brief spikes to 31–32°C before showers return. These factors explain the tight market clustering around 30–32°C, where small differences in convective timing or wind gusts determine whether the daily high settles at 30°C or edges higher. Official Hong Kong Observatory updates through the afternoon remain the key data points for resolution.

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.
