Summary
Hong Kong began Saturday under cloudy skies with showers and thunderstorms linked to an upper-air disturbance affecting the Pearl River Estuary. Rain was particularly heavy in some areas during the morning, with more than 30 millimetres recorded in many places and more than 70 millimetres in Sai Kung and Lantau. The Hong Kong Observatory issued a special weather reminder at 4:10am and said whether a Red Rainstorm Warning Signal would be needed would depend on the development of the thunderstorm area. The Amber Rainstorm Warning Signal was later cancelled at 9:10am after being in force for more than five hours.
Key Points
- At 8am on Saturday, the Observatory recorded a temperature of 26 degrees Celsius and relative humidity of 93 per cent in Hong Kong
- The average UV Index at King's Park in the previous hour was 0.2, which the Observatory classified as low
- Thunderstorm warnings were in force on Saturday morning, with the Observatory expecting a few thunderstorms over Hong Kong.
- Saturday's forecast was mainly cloudy with showers, occasionally heavy rain in the morning, and a daytime high of about 30 degrees Celsius.
- The outlook said showers would persist on Sunday, northerly winds would strengthen at night, and morning lows would fall to around 24 degrees in the following days.
Why It Matters
The morning downpours and thunderstorms affected multiple districts, showing how quickly localized rain can intensify across Hong Kong, especially in places such as Sai Kung and Lantau. The forecast of a cooler, drier spell after the weekend also points to a noticeable shift in conditions that could affect outdoor plans and travel over the next few days.
