Prior to the shifting to Poona India Meteorological Department had its Headquarters at
Simla. The transfer of Headquarters from Simla to Poona was approved by the
Govt. in early 1926. The first section transferred to Poona started functioning
by the end of March, 1928 and the All India Weather Report started being
published from Poona from 1st April, 1928. The building was
completed in June 1928, and the opening ceremony of the new H.Q. building of the
India Meteorological Department was performed by then Governor-of Bombay, Sir

the middle of 1928. Poona (now Pune) continued to be the headquarters of the
Organization till the outbreak of second World War in September,1939. As the
IMD Headquarters was shifted from Simla to Pune, the Pune Met office is
popularly known as " SIMLA OFFICE ".
