Current forecasts from the Hong Kong Observatory and meteorological services indicate a minimum temperature of 27–28°C for August 18, 2026, under typical subtropical summer conditions with high humidity, scattered showers, and no significant cold fronts or typhoon influences. These align with seasonal outlooks projecting normal to above-normal temperatures for August–October amid ongoing climate trends, while daily model guidance consistently shows overnight lows in this narrow range due to persistent warm air masses and limited nocturnal cooling. Trader consensus, reflected in the dominant 28°C (65%) and 27°C (31%) implied probabilities, incorporates these official projections and historical August baselines around 26–28°C, with lower outcomes remaining remote absent unexpected atmospheric shifts.

This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 18 Aug '26.
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
This market can not resolve until data for this date has been published.
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.Current forecasts from the Hong Kong Observatory and meteorological services indicate a minimum temperature of 27–28°C for August 18, 2026, under typical subtropical summer conditions with high humidity, scattered showers, and no significant cold fronts or typhoon influences.
