There are several great subscription and free services that make raw and enhanced oceanic satellite imagery available for anglers to use to find currents, sea surface temperature spreads, and particularly, temperature breaks where the warm currents flow through areas of colder, more nutrient rich oceanic pools. The ocean's surface is extremely dynamic, with major currents running along the coast in constantly changing paths along the continental shelf, and associated with this are areas of comparatively intense fishing activity. However, unless you've got access to real time satellite feed data, most of this information is hours old by the time you get to see it on a website. 
If however, you want to see where the core of the coastal current is in real time as you leave the harbour, or as you approach the edge of the shelf, here are a couple of basic observations, - one using the live BOM weather radar feed, and one simply using what you see on the horizon - that could will help you position yourself right in the thick of the action.
