San José Weather Station History
The United States Weather Bureau opened an office in San José on October 1, 1905. The office and weather instruments were located in the Dougherty Building on South 2nd Street near San Fernando Street. This building was destroyed in the 1906 earthquake, and all instruments and records were lost.
The Bureau Opens a New Office
The Weather Bureau opened a new office in the old Post Office Building at Market and San Fernando Streets on July 1, 1906. The Bureau operated this station until August 1933, when federal budget cuts forced its closure. Local farmers objected strongly to being deprived of local weather information and forecasts, but the closure stood.
The City Takes Over
The City of San José offered to continue taking local weather observations, and the Weather Bureau agreed. It transferred all weather instruments and records to City Hall, then located in Plaza Park in downtown San José. City employees made the weather observations, a practice that continued when a new City Hall opened in 1958 at Mission and First Streets in north San José.
