There was widespread mist and periods of rain on March 21. The mist was cleared by a surge of the northeast monsoon which brought along drier air late on March 22. Winds were strong offshore on March 24 and rain gradually eased off the next day.
Another trough of low pressure approached the territory on March 28 and again brought along thundery showers the next day.
It became fine and sunny on March 30. Winds freshened the next day as another surge of the northeast monsoon reached the territory. The weather on the last day of the month was fine but hazy.
No tropical cyclone occurred in the western North Pacific and the South China Sea in the month.
