Taiwan has been hit by its wettest plum rain season in over a decade, with rainfall levels across the nation reaching their highest since 2012. Taipei saw unprecedented precipitation in June, breaking records since weather documentation began in 1897. The Central Weather Administration reported that from May to June, the island experienced an average rainfall of 609.9 millimeters, significantly surpassing the historical average of 440.7 millimeters. This surge in rainfall was attributed to stationary weather fronts, strong southwesterly airflows, and the impact of a tropical storm.
The southern regions of Taiwan were particularly drenched, with some areas recording between 400 and 800 millimeters of rain in the first half of June. In Pingtung County, nearly 1,000 millimeters fell over just three days. Meanwhile, Taipei set a new record for June rainfall, accumulating 870.5 millimeters, marking the highest monthly total since records began.
Looking forward, weather officials anticipate that temperatures will remain normal to above average through September, while rainfall is expected to align with seasonal norms. Authorities have also forecasted the possibility of three to five tropical storms or typhoons approaching Taiwan in the latter half of the year. The development of El Niño conditions in the Pacific Ocean could lead to stronger tropical storms, as these conditions allow storms more time to intensify over warm ocean waters before nearing the region.
As Taiwan’s typhoon season officially commences on July 1, authorities are implementing new coastal wave warning measures to enhance public safety during severe weather events. These precautions are part of ongoing efforts to better prepare and protect the population from potential hazards associated with intense weather conditions.
