Taiwan has just experienced its wettest plum rain season in over a decade, marking the highest nationwide rainfall levels since 2012. Taipei, in particular, recorded unprecedented precipitation during the month of June. The Central Weather Administration reported that the island saw an average rainfall of 609.9 millimeters from May to June, well above the historical norm of 440.7 millimeters. This surge in rainfall resulted from stationary weather systems, strong southwesterly airflows, and the impact of a tropical storm.
The southern region of Taiwan was hit hardest, with rainfall amounts ranging from 400 to 800 millimeters in the first half of June. Notably, parts of Pingtung County faced nearly 1,000 millimeters of rain over just three days. Taipei smashed its previous June rainfall records, receiving 870.5 millimeters, the highest since records began in 1897.
Looking forward, weather officials predict that temperatures will remain normal to above average through September while expecting rainfall to align closely with seasonal norms. Additionally, authorities anticipate that three to five tropical storms or typhoons could approach Taiwan in the latter half of the year. Forecasters have pointed to developing El Niño conditions in the Pacific Ocean, suggesting that these could lead to stronger tropical storms by giving them more time to intensify over warm ocean waters before nearing the region.
With Taiwan’s typhoon season set to officially commence on July 1, authorities are implementing new coastal wave warning measures to enhance public safety during severe weather events. These measures come as part of the island’s broader strategy to better prepare and protect its residents from the anticipated weather challenges.
