Weather service in Brunei Darussalam began in the late 1950's, primarily to serve aviation activities. Over the years since, the demand for meteorological services from other user groups grew, as well as that from the general population. The Brunei Darussalam Meteorological Department (BDMD), as it is officially known as, since 14 January 2013, is Brunei Darussalam's National Meteorological Service and is the authority responsible for provision of meteorological and climate services.

Currently BDMD maintains a weather forecast office that provides warnings, forecast and advisories for government and non-government agencies as well as for the general public.
BDMD is a full-pledged government agency under the auspices of the Ministry of Transport and Infocommunications and represents Brunei Darussalam in international meteorology. Brunei Darussalam became a member of the World Meteorological Organization (WMO) on 26 November 1984.
