**Trader consensus favoring a 29°C peak on September 3 reflects the moderating effects of northwest monsoon flow strengthened by Tropical Cyclone Sadul’s proximity to the Guangdong coast.** Official Hong Kong Observatory guidance projects a maximum of 31°C under partly sunny skies with one or two showers later, yet persistent cloud cover from the cyclone’s outer rainbands and fresh northwest winds (force 4–5, occasionally stronger offshore) limit solar heating and promote boundary-layer mixing. Afternoon observations through early afternoon reached the upper 20s°C across urban stations, consistent with historical early-September maxima near 30.8°C but tempered by reduced insolation and elevated humidity. Model consensus and real-time surface data show little support for breaching 30°C today, aligning with the market’s strong preference for 29°C (61.5%) over 30°C (33.5%). Updated HKO briefings and additional model runs this evening will refine the final daily maximum.

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 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 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.
