Taiwan has recorded its most intense plum rain season in over a decade, with national precipitation levels soaring to their highest since 2012. In particular, Taipei experienced unprecedented rainfall in June, breaking records that date back to 1897. Data from the Central Weather Administration revealed that from May to June, the island received an average rainfall of 609.9 millimeters. This figure starkly surpasses the historical norm of 440.7 millimeters, driven by persistent weather fronts, robust southwesterly winds, and the impact of a tropical storm.
The southern regions of Taiwan were significantly impacted, with rainfall ranging from 400 to 800 millimeters in early June. Notably, Pingtung County saw nearly 1,000 millimeters of rain over a span of three days. Meanwhile, in Taipei, the rainfall reached 870.5 millimeters in June, setting a new benchmark since record-keeping began over a century ago. This unusual weather pattern underscores the intensity of the current plum rain season, which has been marked by exceptional meteorological activity.
Looking forward, weather experts predict that temperatures from now until September will hover around normal to slightly above-normal levels. Additionally, rainfall is expected to align with seasonal averages. Authorities have also forecast three to five tropical storms or typhoons potentially approaching Taiwan in the latter half of the year. This outlook includes the possibility of stronger tropical storms due to developing El Niño conditions in the Pacific Ocean, which could allow these systems more time to gather strength over the ocean’s warm waters before nearing Taiwan.
The official typhoon season for Taiwan commences on July 1. In light of the potential for severe weather, authorities are implementing new coastal wave warning systems to enhance public safety measures. These steps aim to better prepare and protect communities from the impacts of adverse weather conditions as the island braces for the upcoming storm season.
