2022 will be one of singapore's wettest years in the last four decades

Meteorological Service Singapore (Met Service) stated on Monday that 2022 was one of the wettest years Singapore has seen in the preceding four decades (Jan 30).

The Met Service said that 2016 was the sixth wettest year since 1980, with average annual total precipitation around 19 percent more than the long-term average from 1991 to 2020.

Persistent La Nina weather and a negative Indian Ocean Dipole (IOD), which normally result in wetter-than-average conditions over Singapore and the surrounding region, contributed to the higher-than-average total rainfall in 2022.

La Nina is a climatic phenomena in the Pacific area, whereas IOD is a continuous fluctuation in the difference between tropical western and eastern Indian Ocean sea surface temperatures.

The Changi climate station of the Met Service also recorded a total of 210 rain days, the third-highest total after 1973 and 1927, when 222 rain days were recorded.

The Met Service defines a rain day as a day with 0.2mm of rainfall recorded at a rainfall station.

In the last 40 years, last October’s rainfall was the greatest for that month, while the average rainfall for the month was 412.0mm.

The Changi climate station reported 27 rainy days in October, surpassing the previous record of 23.

March 2018 was the wettest March since 2009, according to the Meteorological Service.
