So whether you are crossing an ocean or inshore racing around the cans, the ability to know what the weather is doing and put this information to practical use is of utmost importance for skippers. the advent of the internet has made sourcing information many times easier than in decades past, and for the sailor this means there’s a veritable smorgasbord of weather maps and data readily available at the click of a button, and often free of charge. Couple this with the capabilities of contemporary satellite and 3G communication systems and the latest weather updates can be beamed to your boat in an instant. it is not too long ago that the main sources for weather information for mariners were limited to either recorded telephone services; VhF and hF radio forecasts which were often crackly and sometimes unintelligible; and weather fax broadcasts which produced sporadic and often sketchy pictures that relied on a healthy hF radio signal, familiarity with the characteristics of radio propagation and careful manipulation of the receiving unit to get any kind of legible weather map. radio forecasting is still used aboard many yachts and weather fax is still used aboard some yachts travelling internationally, although normally in a more modern format where the hF radio is connected into the yacht’s PC to provide a digital image. hopefully most mariners have moved on from the days of fnding metres of blackened thermal paper hanging out the bottom of the weather fax machine when the timer has been wrongly set. FREE WIND the internet has now become most sailors’ principal source of weather forecasting information because of its ease of use and the amount of accurate data that can be found. there are many thousands of websites worldwide providing weather information, each with different characteristics and degrees of usefulness. So which one is for you? One of australia’s most comprehensive free sources of weather information is of course the government’s Bureau of Meteorolog y website, normally referred to simply as “BOM”. the site has an easily navigable marine weather area with weather warnings, forecasts, weather charts, tidal information, and historical and statistical information for all areas of australia and the high seas offshore areas surrounding the continent. Coastal and offshore sailors should fnd the BLUElink Ocean Forecasting initiative on the BOM site useful as it maps out the sea temperature and direction and strength of currents around australia’s coastline.
