HK Observatory forecasts occasional gale-force thunderstorms starting from Thursday, lowest temperature to drop to 19°C


18th March 2023 – (Hong Kong) According to the Hong Kong Observatory, the current easterly airstream affecting the coast of Guangdong will be gradually replaced by a southerly airstream in the next few days. As a result, warm and humid conditions with showers are expected over the coastal areas early to midweek next week. Towards the latter part of next week, a trough of low pressure is anticipated to bring unsettled weather to southern China, leading to an increase in showers and thunderstorms over the coastal areas of Guangdong.

Over the next nine days, the Hong Kong Observatory predicts that there will be rain with temperatures ranging between 20 to 24 degrees Celsius. There will be occasional light rain on Saturday and Sunday, followed by a couple of showers from Monday onwards. Afternoons will see brief periods of sunshine, with coastal areas experiencing thin fog at night. Temperatures will gradually rise, with a high of 28 degrees Celsius expected on Wednesday, which coincides with the spring equinox.

However, starting from Thursday, the Hong Kong Observatory forecasts that there will be occasional gale-force thunderstorms, which will persist until Saturday. As a result, temperatures will slightly drop, with the lowest temperature of 19 degrees Celsius expected on 27th March. The wind direction will be mainly southerly to south-easterly at moderate to fresh force, occasionally strong offshore.
