Official Hong Kong Observatory forecasts for September 15, 2026, indicate a daily minimum of 26–27°C under the influence of a northeast monsoon and high-pressure ridge, with observed overnight lows at key stations already settling near 26°C amid partly cloudy skies and scattered showers. This aligns with climatological norms for mid-September, when subtropical highs typically suppress deeper cooling while easterly flow maintains humidity levels above 60%. The market’s 96.5% implied probability on 26°C reflects trader confidence in these model runs and real-time station data, though a stronger-than-expected monsoon surge or localized heavy rainfall could briefly dip readings toward 25°C before dawn.

The resolution source for this market will be information from the Hong Kong Observatory, specifically the "Absolute Daily Min (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.
