On the second weekend in August 2020 a high pressure system paused for a few days as it made its way eastwards over Victoria. There was a strong low off the south east coast of the state. The isobars over the state got closer and the wind got stronger producing two days of easterlies above 30 knots with gale force gusts at times. This was followed by a further two days of progressively abating easterly winds. The driving rain and low cloud that usually accompanies such a system were present, but just a little north of the coast this time.
The main beach at Apollo Bay faces directly east which means easterlies are onshore winds. Strong easterlies create rough seas with white water well offshore and right up to the high water mark on the beaches of the local east-facing bays. Such conditions are bad for boating and worse for swimming. I didn’t see any boats arrive at or leave the harbour over the weekend. I don’t swim in the ocean in these conditions. Apart from the general rough seas, the local rips and currents seem to go into overdrive in such conditions and there is a lot of water moving around in the 200-300m closest to shore.
The harbour is a good alternative in such conditions as the 475m long north-south aligned breakwater protects the harbour water immediately in its lee. During this period of strong easterlies I swam in the calm waters of the eastern side of the harbour but also tried another potential alternative I have considered for some time, the Barham River. A few GoPro snaps from that swim are included in this post.

Barham River Swim
The Barham River flows out to the sea just south of Point Bunbury at Apollo Bay. I have long thought it might be a pleasant swim along this river. I swam a lot in the Barwon River in Geelong as a boy, so the notion of swimming in muddy water with muddier banks doesn’t bother me. Of course, clear ocean water is far and away my first preference. The vision I had in mind for re-visiting river swimming was tranquil water as shown in the photo below, with the rich farmland on the fertile river flats and the distant foothills of the Otways offering a continuous series of calendar shots to my left and right.

High and Dry
Each receding tide during a period of strong onshore winds leaves a higher than usual volume of kelp, seaweed and other things that washed ashore. Bull kelp (also know as string kelp) and other brown algae and seaweed line the high watermark when the easterly winds blow.
These photos record two consequences of not keeping an eye on the tide charts and the approaching waves. They are related in that I was busy taking a photo of the pufferfish (or porcupine fish – one type of the large and varied group of puffer fish) and paying no attention to the sea when the incoming tide brought a small wave to my feet. Well, to my legs to be precise. The pufferfish appears to have come too close to shore in the 30 knot easterly to be able to resist being washed ashore and stranded.
Pufferfish contain a powerful poison called ‘tetrodotoxin’. It is said to be many times more dangerous than cyanide. It’s stored in their skin and internal organs. The spines are merely sharp and don’t contain the toxin. Touching a pufferfish is not a good idea. Eating one could kill you. They are found in shallow temperate waters world wide.
