The basic source for a Sydney weather forecast is the Australian Bureau of Meteorology, affectionately known by locals as the BOM. All media outlets rely on the BOM as their source of weather information. There are very few private weather forecasters and they have a very limited client base.
The BOM makes special efforts to provide mariners at sea with weather information tailored to their needs for Sydney and other coastal regions around Australia. It distributes this information in a variety of ways, including communicating it to relevant maritime authorities who then broadcast the information over standard maritime radio frequencies (channels).
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.
AMSA network broadcasts high frequency (HF) radio transmissions to mariners. The network provides automated transmissions of weather forecasts for the high seas and coastal regions. Its broadcasts are designed to reach mariners located at great distances from the coast, hundreds and even thousands of miles offshore.
The next section, the middle left, provides a list of each of the Australian capital cities and provides the current and forecast temperature for each. The forecast temperatures are hyperlinked; clicking the desired city carries the visitor to a page containing a full weather forecast for that city. Capital city weather forecasts published on the BOM website are updated at least two times each day, once at about 1600-1700 hrs and again at 0400 to 0500 hours.
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 24×7 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.
The CRN stations may, on an optional basis, monitor for distress calls on VHF channel 16. They may also, again on an optional basis, transmit local weather broadcasts on channels 16 and 67. Radio broadcasts using very high frequency (VHF) signals are accessible by mariners positioned on inshore waters, that is, within relatively short distances from the point of transmission. VHF broadcasts are not designed to reach mariners on the high seas.
Naturally, a Sydney weather forecast is accessible at any hour each day every day to anyone with an Internet connection. The BOM forecast is updated several times a day.
