TAIPEI (CNA) — The total rainfall in Taiwan in May and June this year will be average, but most of the plum rains, as they are called, will fall later in the season, the Central Weather Bureau said Tuesday.

May might be slightly drier than usual, but the total rainfall in June is expected to be on par with previous years, Lu Kuo-chen (呂國臣), director of the bureau’s Weather Forecast Center, said at a press conference.

The annual plum rain season, which typically starts with the onset of the southwest monsoon, is forecast to begin in northern Taiwan in early May and in the southern part of the country mid-May to June, as has been the pattern in recent years, Lu said.

The average rainfall in the May-June period is 560.4 millimeters in Taipei and 612.7 mm in Kaohsiung in the south, according to CWB data.

Nationwide, the total rainfall during the plum rain season ranges from 300mm to 1,000mm, the data shows.

Meanwhile, Lu said Taiwan recorded warmer than usual temperatures in February and March, although it experienced nine cold fronts during that period.

In April, however, the average temperature so far of 23.11 degrees Celsius has been 1.38 degrees below normal, which has set a record as the coldest April in Taiwan since 1996, Lu said.
