Taiwan Governor-General Weather Observatory

The Taiwan Governor-General Weather Observatory (臺灣總督府氣象臺) traces its origins to the Taihoku (Taipei) Observatory (臺北測候所) established in August 1896, shortly after Japan assumed control of Taiwan following the Treaty of Shimonoseki in 1895. Recognizing the strategic importance of meteorological data for both colonial administration and military operations in the western Pacific, the Japanese government quickly established weather stations across the island, with the Taipei Observatory serving as the headquarters of the network.

On December 19, 1897, the Taipei Observatory relocated to its present site on Park Road (公園路) in Taipei's Zhongzheng District. The original 1896 network comprised five stations in Taipei, Taichung, Tainan, Hengchun, and Penghu; over the following decades further stations and numerous smaller observation posts at lighthouses, government offices, police posts and post offices were added across the island. In 1938 the Taipei Observatory was upgraded to the Taiwan Governor-General Weather Observatory, overseeing all meteorological and seismological observation in Taiwan and Penghu.

During the Second World War, the observatory's role became increasingly militarized. It provided essential weather forecasting services for Japanese naval and air operations across the Pacific theater, including typhoon tracking critical for fleet movements and aviation route planning. The observatory's data was integrated into the broader Imperial Japanese military meteorological network, supporting operations from Southeast Asia to the central Pacific. Taiwan's geographic position made its weather data particularly valuable for predicting conditions affecting the Philippines, South China Sea, and Okinawa campaigns.

Following Japan's surrender in August 1945, the Kuomintang government took over the observatory and its island-wide network of stations. The institution was reorganized multiple times — becoming the Taiwan Provincial Weather Institution, then the Central Weather Bureau in 1971, and most recently the Central Weather Administration (中央氣象署) on September 15, 2023. Throughout these transitions, the headquarters has remained at or near the original 1897 site on Park Road.

Today, the Central Weather Administration building stands as the institutional successor to the colonial-era observatory. While the original Japanese-era structures have been replaced by modern facilities, the administration preserves historical instruments from the Japanese period, notably at its meteorological museum in the former Tainan Weather Observatory, maintaining a tangible connection to over a century of meteorological observation at this location.
