Taiwan is witnessing its most intense plum rain season in over ten years, with rainfall levels reaching unprecedented heights since 2012. Notably, Taipei experienced record-breaking precipitation in June, marking the highest levels since records began in 1897. The Central Weather Administration reported that the period from May to June saw an average of 609.9 millimeters of rain across Taiwan, far 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.
Southern Taiwan bore the brunt of these heavy rains, particularly in regions like Pingtung County, where some areas saw almost 1,000 millimeters of rain over just three days. During the first half of June, several locations received between 400 and 800 millimeters of rain. Meanwhile, Taipei set a new record for June rainfall with 870.5 millimeters, underscoring the severity of this year’s weather conditions.
Looking forward, meteorologists anticipate that temperatures in Taiwan will remain normal to above average through September. Rainfall is expected to align with typical seasonal levels, but authorities also forecast the potential for three to five tropical storms or typhoons to pass near the island during the latter half of the year. The developing El Niño conditions in the Pacific could enhance the intensity of these tropical storms, as they allow for more time to strengthen over warm ocean waters before impacting the region.
With Taiwan’s typhoon season officially commencing on July 1, new coastal wave warning measures have been introduced to bolster public safety during severe weather events. These preparations are essential as the nation braces for the upcoming storm season, ensuring that communities are better protected against the potential threats posed by increased storm activity.
