Current forecasts from the Hong Kong Observatory and global models point to minimum temperatures near 27–28°C on June 20, consistent with above-normal seasonal outlooks for June–August amid ongoing climate warming trends. High humidity above 80 percent, widespread cloud cover from showers, and light winds limit nocturnal radiative cooling in this subtropical environment, keeping overnight lows elevated compared to drier conditions. Trader sentiment clusters around these values because ensemble guidance shows only modest day-to-day variability, with resolution hinging on precise timing of any convective activity or changes in boundary-layer moisture that could shift the minimum by 1–2°C. Historical June averages near 27°C provide the baseline against which short-term model updates will be measured.

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.
