February was gloomier and more humid than usual, with the mean relative humidity 8% higher than normal and ranked the fourth highest for February. The total duration of bright sunshine was only 34.4 hours, about one third of the normal figure.

Hong Kong Observatory explained the foggy and cloudy weather resulted from the tug-of-war between the northeast monsoon and the maritime airstream around the south China coast. The monthly mean relative humidity was 86%. Despite the humid weather, the monthly rainfall of 19.2 millimetres was 28.8 millimetres less than normal.

Under the influence of the winter monsoon, it was cold and overcast with rain patches in the first three days of February. On February 4, the temperature started to rise gradually when a maritime airstream set in. The maritime airstream also brought foggy weather to Hong Kong waters for five consecutive days.

A cold front moved across the south China coast during the day on February 10. It became cooler the next day. Although there were sunny periods on February 12, it turned cloudy again on February 13 and 14. 

A maritime airstream brought humid and foggy weather to the city again in the next three days. On February 17, a cold front arrived at the coast of Guangdong, bringing cold and overcast weather to Hong Kong in the following five days. The temperature in the urban area dropped to 9 degrees Celsius on February 20, the lowest of the month.

Fog returned on February 23 when Hong Kong once again came under the influence of a maritime airstream. The visibility at the Hong Kong International Airport once fell to about 200 metres in the morning of February 25, leading to the delay and diversion of 46 flights and cancellation of 17 scheduled ferry trips between Hong Kong and Guangdong. The arrival of an intense northeast monsoon later during the day eventually cleared the fog. It was windy, rainy and cooler in the following two days.

It was cold and rainy on the last day of February. The month saw no tropical cyclone over the South China Sea and the western North Pacific.
