Checking the weather
You’ll find marine weather forecasts are available from many different sources.
The Australian Bureau of Meteorology broadcasts marine weather information on the existing radio working frequencies. These broadcasts are made on a 24 hour, 7 day a week basis with the schedules available via the Bureau's website.
Part of good seamanship is using all available means to check the weather. That can range from marine radio broadcasts, to media, newspapers, AM and FM radio, the television and of course the internet.
However, you should never underestimate the value of your own judgement, especially once you've taken the time to understand weather patterns. If you’re in doubt, just don't go out.
