The Hong Kong Observatory warned Saturday of a prolonged stretch of “unstable weather” set to drench the region through the upcoming spring holidays, as humidity levels are expected to remain near saturation for over a week.
A low-pressure trough and a humid easterly airstream began moving across the Guangdong coast Saturday afternoon, bringing cloudy skies and scattered showers to the city. While afternoon temperatures hovered between 23 and 27 degrees Celsius, forecasters say the atmosphere is rapidly becoming “muggy.”
According to the Observatory, maximum relative humidity is forecast to reach 90% or higher every day for the next nine days. This persistent dampness marks a soggy start to the local spring season, often characterized by heavy sea fog and persistent drizzle.
Meteorologists anticipate a brief spike in temperatures early next week as a southerly airstream takes hold. Highs on Monday are expected to hit 29 degrees Celsius (84 degrees Fahrenheit) with sunny intervals. However, the heat is likely a precursor to more volatile conditions.
By Tuesday, the approaching trough is expected to trigger more frequent showers and thunderstorms. This pattern is projected to persist through the mid-week and disrupt the upcoming long weekend.
Holiday travelers and residents planning outdoor activities for Good Friday (April 3) and the following Saturday should prepare for mostly cloudy skies, periods of rain, and localized thunderstorms.
The outlook remains similarly gloomy for the Ching Ming Festival on April 5. Forecasters expect lingering showers and early morning lightning to mark the traditional day of ancestral remembrance.
While temperatures will fluctuate slightly between 23 and 28 degrees throughout the week, the Observatory warned that the defining features of early April will be “persistent dampness and the risk of sudden downpours.”
