Port Phillip Bay

Port Phillip Bay is one of the largest inland seas in the Southern Hemisphere.  Connected to Bass Straight and the associated Southern Ocean.

The heads are narrow leading into a shallow, broad and very beautiful bay. It is its size and shallowness that result in conditions that can change rapidly from calm and docile to life-threatening when it comes to small boats.

What Weather conditions affect the Bay?


Port Phillip is subjected to a wide variety of weather patterns.

While it is often calm it can change dramatically in a very short space of time.

The influence of Bass Straight and associated weather patterns from the Southern Ocean being a major driver of weather and bay conditions.

However, it is also affected by inland weather conditions that can be equally variable.  Strong northerly winds can make boating more risky at times – including producing sudden summer squalls.

Because of this, a keen eye on the weather conditions is a must – whether you are fishing off a boat or a pier.  As even the piers can, in some circumstances, be dangerous.

The Weather Bureau’s website provides regular updates on bay conditions and should be consulted before – and during bay activity.  Particularly if you are boating.
