Taiwan is grappling with its wettest plum rain season in over ten years, marked by the highest rainfall levels since 2012, with Taipei experiencing unprecedented precipitation in June. During this May-to-June rainy period, the island averaged 609.9 millimeters of rain, significantly surpassing the historical norm of 440.7 millimeters, according to meteorological data. This surge in rainfall was attributed to stationary weather fronts, robust southwesterly air currents, and a tropical storm’s influence.
The southern regions of Taiwan were notably impacted, with certain areas recording between 400 and 800 millimeters of rain in the initial weeks of June. Particularly in Pingtung County, some localities experienced almost 1,000 millimeters of rainfall in just three days. In Taipei, June’s rainfall reached 870.5 millimeters, establishing a new record since weather monitoring began in 1897.
Looking forward, weather authorities anticipate temperatures to range from normal to above average through September, while rainfall levels are expected to align with seasonal norms. Furthermore, officials have projected that Taiwan could encounter three to five tropical storms or typhoons during the year’s latter half. The evolving El Niño conditions in the Pacific Ocean may exacerbate these storms by providing additional time for them to strengthen over the warm waters before nearing Taiwan.
With Taiwan’s typhoon season officially commencing on July 1, government agencies are implementing new coastal wave warning systems to enhance public safety amid severe weather conditions. This proactive measure reflects the need for heightened preparedness in the face of potentially stronger storms fueled by climatic shifts.
