Macau marked the Beginning of Spring, known in Putonghua as “Lichun”*, the first of China’s 24 solar terms, yesterday, but the local observatory stressed the solar term does not mean that spring weather has necessarily arrived, noting that strong winter monsoon conditions remain common during the period.
According to a statement by the Macau Meteorological and Geophysical Bureau (SMG), Lichun traditionally symbolises the beginning of growth and the revival of nature. However, the statement underlined that Macau’s subtropical coastal location means that this month is still considered the tail end of winter, with weather mainly influenced by northern systems.
When strong continental cold highs move southward or shift eastward into the sea, Macau may experience dry and cold northerly or easterly winds. The statement noted that if the pressure gradient increases, local wind strength can intensify rapidly.
According to the statement, the bureau will issue a “Strong Monsoon Signal” when wind speeds reach or exceed 41 kilometres per hour, a warning commonly known among residents as the “black ball”.
From 2016 to 2025, during the beginning of spring – from the day of Lichun until the day before the Rain Water solar term (Yushui), – the bureau issued a total of 14 “black ball” warnings. The statement noted that 2022 recorded the highest number in a single year, with four warnings, reflecting particularly active cold air conditions.
Yushui (雨水) is the second of the 24 traditional Chinese solar terms, usually starting around February 18-20.
The statement also reminded residents that strong winds often occur along the leading edge of continental cold highs, advising the public to take precautions.
Meanwhile, the weather station urged residents to avoid staying in open areas for long periods, while those working at sea or engaging in water activities are advised to remain highly alert, the statement said, adding that the public is also reminded to pay close attention to updates from the local observatory, including the “Strong Monsoon Signal” and the “Bridge Strong Wind Alert,” as well as to prepare in advance by taking necessary wind prevention measures to ensure personal and property safety.
The statement said that while Lichun marks the beginning of spring in the traditional calendar, Macau is still prone to winter monsoon conditions during early February, and residents should remain cautious of strong winds.
* Lichun (立春) is one of the 24 solar terms in the Chinese calendar, marking the transition from winter to spring. Lichun typically falls around February 4th or 5th, depending on the year, and is associated with the awakening of nature and the start of agricultural activities.
