Recent Hong Kong Observatory and multi-model consensus forecasts point to typical late-June subtropical conditions, with overnight radiative cooling limited by high humidity, persistent cloud cover, and light southerly flow, keeping the minimum temperature near 27–28 °C on 30 June. Seasonal outlooks already indicate above-normal temperatures for the month, and no approaching trough, typhoon, or frontal system is expected to enhance cooling or introduce variability before resolution. Historical June minima average 26–27 °C, so the tight clustering of market-implied odds around the 27 °C and 28 °C outcomes reflects modest model spread in boundary-layer moisture and wind speed rather than any dramatic shift in the synoptic pattern.

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.
