Hong Kong Observatory's latest 9-day forecast, updated April 3, projects a daytime high of 27°C on April 5 amid a lingering trough of low pressure over southern China, bringing mainly cloudy skies, occasional showers, and squally thunderstorms with high humidity (75-95%) and southerly winds force 3-6. This aligns with the monthly outlook for above-normal temperatures in April, yet trader consensus splits closely between 26°C (32.5%) and 27°C (30%), reflecting uncertainty in cloud cover's impact on solar insolation and potential for brief sunny breaks allowing peak heating. Southerly airflow moderates extremes, while historical early-April highs average 25-26°C; daily updates tomorrow could refine model consensus as the anticyclone aloft strengthens later in the week.
