Recent Hong Kong Observatory forecasts project a minimum temperature of 27°C for June 19 amid sunny periods with a few showers and moderate rain probability, supporting the near-even market split between 26°C and 27°C outcomes. In Hong Kong’s subtropical monsoon climate, overnight lows during early summer typically range 25–28°C due to high humidity limiting radiational cooling, variable southerly winds, and cloud cover from convective activity. Model consensus shows slight differences in boundary-layer moisture and wind speed that could tip the minimum by 1°C, with historical June data clustering around these values. Traders are weighing the latest multi-model guidance and any HKO updates ahead of the 24-hour observation window at the official station.

This market will resolve to the temperature range that contains the lowest temperature recorded by the Hong Kong Observatory in degrees Celsius on 19 Jun '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.Recent Hong Kong Observatory forecasts project a minimum temperature of 27°C for June 19 amid sunny periods with a few showers and moderate rain probability, supporting the near-even market split between 26°C and 27°C outcomes.
