Recent Hong Kong Observatory forecasts and multi-model consensus indicate a minimum temperature of 26°C for June 15, with expected thunderstorms and showers moderating overnight cooling amid above-normal seasonal temperatures. Persistent high humidity, northeasterly winds, and cloud cover from the active monsoon trough are limiting radiative heat loss, keeping lows clustered near 26–27°C rather than dropping toward the long-term June average of 25–26°C. Model agreement on these conditions has concentrated trader positions on 26°C as the modal outcome, while slight uncertainties in rainfall timing and intensity support secondary probabilities for 25°C or 27°C. Updated HKO guidance ahead of the 15th could refine these implied probabilities if convective activity strengthens or weakens.
