The originating source for the Sydney weather forecast is the Australian Bureau of Meteorology, referred to locally as the BOM. Media outlets rely on BOM forecasts. Details provided by TV, radio, newspapers and the Internet sources are based work by the BOM.
The BOM provides special services for mariners. The BOM passes on its information to several maritime agencies. These authorities broadcast it via marine radio. There are three distinct Australian marine radio networks, namely, the Coast Radio Network, the network operated by the Australia Maritime Safety Authority and, finally, the Volunteer Coastal Stations. All three services relay BOM weather reports, both warnings and forecasts.
3There are three types of maritime radio communication networks in Australia. In addition to monitoring for distress calls, they also transmit weather forecasts and warnings produced by the BOM. The three services are the Australian Maritime Safety Authority (AMSA) network, the Coast Radio Network (CRN) and Volunteer Coast Stations. All three networks broadcast weather forecasts.
The far left of the home page provides a list of services presented on the BOM website. These include not only weather services but also climate services, water information services, water and the land (agricultural services), ocean services, marine services, aviation services, a tsunami warning services, registered user services and commercial services for which a fee is charged. There is some overlap in the detailed information provided under each of these tabs. For example, the water information services tab and the water and the land (agricultural services) tabs each provide, in some instances, links to the same data items.
The AMSA radio network consists of two radio stations, one at Charleville (Queensland) and the other at Wiluna (Western Australia). These two remote, inland towns may seem absurd locations at which to locate bases for marine radio transmissions, however they are considered electronically quiet with an absence of interference that is geographically rare. The respective call signs for services from these stations are VMC Australia Weather East for Charleville and VMW Australia Weather West for Wiluna.
The CRN consists of nine state-government operated HF coast radio stations located at Sydney as well as Gladstone, Cairns, Darwin, Port Hedland, Perth, Adelaide, Melbourne and Hobart. They typically are situated in the Port and Harbor Control Towers at the respective nine locations. The ID for each of these nine stations is Coast Radio Sydney, Coast Radio Gladstone and so on. The stations monitoring for distress calls from vessels 24x7 on frequencies 4125, 6215 and 8291 kHz. It is estimated that a vessel within 200 nautical miles of the Australian coast making a distress call will be heard by at least two CRN stations. Note these stations do not monitor the frequency of 2182 kHz.
CRN bases may monitor for distress calls on VHF channel 16, however this is done at the option of each station. Also, again at their option, they stations may transmit local weather reports on channels 16 or 67. Radio broadcasts at very high frequency (VHF) are designed to reach receivers in coastal waters not the high seas.
Naturally, a Sydney weather forecast is available 24x7 to anyone anywhere in the world provided they have an Internet connection and can access the BOM website. The forecast is routinely revised with updated information at least twice per day.
