Forecast models from the Hong Kong Observatory and regional guidance indicate a daily maximum near 28–29°C on June 11, consistent with the closely matched market-implied odds around those levels. Persistent cloud cover and scattered showers or thunderstorms, driven by the early summer monsoon trough, are expected to limit daytime heating and keep temperatures from reaching the seasonal climatological peak. Above-normal June–August temperatures signaled in the latest HKO seasonal outlook provide a slight upward bias, yet short-term variability in rainfall timing and wind patterns introduces uncertainty that differentiates the 28°C, 29°C, and 30°C outcomes. Updated model runs and official daily forecasts in the next 48 hours will refine the precise maximum.

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.
