History
Before World War II, weather observations in Fiji were the responsibility of the harbour board and limited to recording various meteorological details at various locations around the island nation. During the 1939 Defence Conference in Wellington, New Zealand, Fiji's capital Suva was identified as the location of an upgraded meteorological service for the Pacific region. As a result, a facility was established at Laucala Bay during 1940, before it was expanded during the following year to support the operations of the Royal New Zealand Air Force. After the United States of America entered the war, meteorological operations were started at the Nadi Airport by the United States Army Air Forces Meteorological Unit during 1942.
After the war, the Nadi Weather Office (NWO) was converted to a civilian unit, before Laucala Bay's forecasting unit was moved and merged with Nadi's forecasting unit.

Its specialty is forecasting tropical cyclones south of the equator to the 25th parallel south, and between the 160th meridian east and 120th meridian west longitude. FMS issues public and marine weather bulletins for Kiribati, Northern Cooks, Southern Cooks, Tuvalu, Tokelau, Niue, Nauru and Fiji. The Fiji Meteorological Services, as per agreement with the International Civil Aviation Organization, functions as the Meteorological Watch Office for the Nadi Flight Information Region (FIR), which extends from Western Kiribati to Tuvalu, Fiji, Vanuatu, Wallis and Futuna and New Caledonia.
