V.J. Bahr, the first Officer-in-charge of the Charleville Office, wrote "the commencement of Meteorological Services had their genesis in the need to provide vital strategic support connected with the desperate defence of Northern Australia following the rapid advances of the Japanese through South East Asia, Papua New Guinea and the Islands to the North and Northeast of Australia, and the disastrous bombing raids on Darwin on 19 February 1942".

The office's role has undergone changes over the years with steady improvement in the equipment used to carry out its functions. The more significant equipment changes/upgrades include: June 1943-Radio Sonde equipment installed; October 1955-Type 277F radar installed in newly constructed RadioAids building near the aerodrome entrance; September 1958 Sferics lightning-detection equipment installed - similar equipment was installed at Brisbane Airport and Townsville Met. offices and these stations formed the Queensland Sferics Network; December 1983-WF 100 Windfinding radar; August 1990-MICROMAC Automatic Weather Station (AWS); May 1991-PC-Cora (computerised radio sonde system).

The forecast and pilot-briefing function of the office moved in 1960 to the new DCA complex which was situated in close proximity to the aerodrome passenger terminal. Met. and Flight Service staff worked in adjacent offices. The RadioAids facility functioned as an upper-air monitoring station at the same time. With the commissioning of the AWS in 1990, all station functions were consolidated into the RadioAids building.

Met. office staff overcame significant personal hardships during the devastating April 1990 flood. Some 2000 residents of the area were evacuated to a large hangar on the airport, prior to further evacuation of many of these people to other towns and cities. From the onset of the flood until early June the Met. staff (total 6 officers) lived and worked at the Met. RadioAids building on the aerodrome, whilst their families had been evacuated out of Charleville.

The Charleville area was the focus for weather experimentation long before the establishment of a weather office in the area. In 1902 the Queensland Government Meteorologist (Professor Clement Wragge) placed Steiger Vortex Guns around Charleville, with a view to firing these into the atmosphere in an attempt to induce rain to ease a drought, which was prevalent at the time. Whilst the experiment failed, the interest surrounding the event is remembered by way of a monument in the city.
