Recent forecasts from the Hong Kong Observatory and global models indicate typical June highs of 28–32°C under the southwest monsoon, with persistent humidity above 80% and scattered showers limiting solar heating. Trader consensus clusters around 31–33°C because variable cloud cover and timing of precipitation can suppress peak temperatures by 1–3°C on any given day, while brief clear intervals or reduced rainfall allow brief spikes toward 34–35°C. Historical June climatology shows a 30–32°C average maximum, but model spread in the 48-hour window introduces uncertainty around exact insolation and boundary-layer mixing, keeping lower (≤30°C) and extreme (≥36°C) outcomes less favored yet plausible if steering patterns shift.

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