Spring arrived as if a switch had been flicked. The air is warmer, the sun is brighter and the ocean somehow no longer looks wintry. Well, at least that was how it looked before the gale force winds arrived.
All these photos were taken in the first 7-8 days of spring 2020.
A morning ocean swim under a clear blue sky
This beach is 300m from my front door. It’s not always this calm.
I was the only person in the water when I swam. The wind was very light and on my back as I entered the water.
The figures on the beach in the centre of the image are Sue and Marion, swimming friends of mine. They were walking north to enjoy the swim back to the harbour wall in these conditions. I have taken better portraits of my friends. This was taken during a pause in my swim when I was directly out from the surf life saving club.
Glassy green waves standing up over the sandbar.
Behind the wave as it breaks. That’s not rain hitting the water, but spray which the offshore wind was blowing over the back of the wave as it broke. It falls like rain, and pings on my wetsuit hood or cap just as rain does.
More spray being blown over the back, not rain. Marriners Lookout on the horizon. A cold front passes over Apollo Bay
We woke to near gale force winds this morning. A cold front was approaching and the north westerly wind increased in strength as it got closer. I timed my morning swim to coincide with the arrival of the front. Cloud cover increased and the wind slowly backed around from NNW to NW and eventually around to the W. It progressively eased as the front moved through and headed for Melbourne and eastern Victoria.
Unlike swimming conditions in recent days, the sun struggled to put in an appearance. The best it could manage through the thickening cloud was this pale white light which looked more like moonlight over the water than morning sun on a spring day.
As the cloud cover increased the sun’s last hurrah before the front and the rain arrived was this weak torchlight display over Cape Patton.
Then the sun disappeared behind the cloud that arrived with the front. I was swimming not far from shore over the sandbar which is where the waves were standing up green and clean (as shown) before breaking in the shallows. This wave is very similar to the wave in the fourth photo in this post. But the difference in the light (sunny skies compared to dull overcast) casts a very different colour and appearance on the water.
Some ocean swimming markers
Most of my ocean swimming is done between the Apollo Bay harbour wall and points north. Some trips are one-way, but mostly they are out and back swims. The Tuxion beach steps, the wooden lookout structure on the dunes and the surf life saving club building are frequently used distance measuring and/or turning points. The following three images show these locations. Use the slider to better locate these reference points.
These photos (and a few others in this post) were taken with my GoPro camera on a dull day while rain was falling. The GoPro (or at least the model I have) excels in bright light but not otherwise. Apologies for the lack of clarity, especially on the magnified parts of these three photos.
The steps at Tuxion beach on a day of very small swell. When we swim in solid swell it is usually much bigger at this spot than in the south of the bay near the harbour wall where in most conditions the water is more protected. There are days when we have swum north from the wall and paused directly out from these steps before swimming back that the size and force of the breaking surf between us and the shore (we swim well offshore on such days) is enough to make the 800m return swim back to the wall a decidedly more attractive option than swimming ashore through such shorebreak. Sometimes the distance from shore we have chosen to ensure we stay seaward of the big breaking waves proves to have been underestimated and we have to duck dive under a breaking wave as a big set comes through and breaks seaward of us.
The lookout. This is located just 100m or so south of the servo (another popular turn point and distance measurer) or Thompson St to be more formal. The lookout has a peculiar non-rectangular plan form such that there are quite a number of spots out to sea from which it can be viewed and from which it appears you are on a line at 90° from the shore. Accordingly, I consider myself directly east of it when the light pole some distance behind it appears in line with the lookout, as shown.
The Apollo Bay Surf Life Saving Club building. The marker here for me is the clearly defined track through the dunes in front of the clubhouse. I consider myself at this landmark when I can see the fence on both sides of this track.
Rain drops, not spray from a breaking wave
One reason for planning my ocean swim to coincide with the arrival of the cold front and the band of rain it brought, was the hope of swimming in strong winds and heavy rain for a short time, perhaps with a bit of thunder in the distance for atmosphere. As anybody who has done it can attest, swimming in such conditions is most enjoyable. But it was not to be. Instead of rampaging across Apollo Bay, this front just sauntered in to town, taking its time, being polite, saving its thunder for some other day and providing merely grey clouds and steady light rain with not much wind at all. I don’t believe any rain even registered in the gauge. This photo shows a few raindrops, not spray from breaking waves. The swim was still very pleasant. There was a small bit of swell between me and the harbour when I took this photo. Near the top left of the image the masts of yachts in the harbour are visible. Silver gulls at Peterborough
The mature silver gull has bright orange bill, legs and eye rings. These birds were juveniles. The colour of the legs etc on these birds has been faithfully reproduced in these photos.
This photo was taken on a cold day. This bird looked very cosily covered in feathers to survive the cold air temps and colder sea temps on the Victorian coast in winter. This might be a ‘Peterborough and surrounds’ evolutionary thing for silver gulls. It can be very cold there by the sea in winter.
What a fine, healthy and self-assured looking specimen. Am I imagining just a hint of sternness in where its right eyebrow would be if it had one? It did not tolerate me getting very close to it. This was taken with a large telephoto lens. A calm, golden evening at Apollo Bay
Apollo Bay harbour late afternoon. I generally consider buying a cruising yacht on these walks. But when I mention it to Liz, she says ‘Fine’, then adds, ‘Write to me.’ She has a way with words.
The fleet of working and recreational boats. Only one visiting boat that I could identify here. A local sailor could probably spot more.

Where Apollo Bay beach meets the harbour wall. The locals call this protected beach Mothers’ Beach. Gale force winds ahead of another cold front
This cold front brought very strong winds to Victoria, especially along the coast. Close isobars, steep pressure gradient, stronger winds, wind blowing anticlockwise around a high and slightly angled across the isobars to the outside of the system etc etc
I woke to gale force winds rocking the house. I drove to Hayley Point as soon as it was light, as this is where the interesting stormy seas in the area are usually seen at their best. But as this weather event was a big wind, not a big swell, there wasn’t much to see in Mounts Bay. There was a bit of swell as shown above but it wasn’t getting a chance to stand up at all. The 35-40 knot wind was flattening the waves and blowing the breaking crests back at water level, not in the elegant rising and curving manes of white water seen behind big surf in normal offshore winds.
So I drove to Pt Bunbury (near the golf course in Apollo Bay). This is an easterly point surrounded by sea on three sides. With the wind howling in from the NW, there was a fetch of some kms of ocean between the north of the bay and Pt Bunbury. Of all the local vantage points the wind would be strongest here. This is because the stretch of relatively frictionless ocean over which the wind had blown since it left the land in the north of the bay was long enough to allow the wind to accelerate at sea level in a way it cannot accelerate at ground level over hills, trees, houses and other obstacles which create friction and which hold it back. So I chose an elevated green on the windward side of this point from which to measure the wind speed.
I measured the wind at Pt Bunbury at 41 kts (76kph). This is a Hall wind gauge used by hang glider pilots. It is calibrated in knots and is quite accurate. It can be used as shown to measure wind speed. Alternatively, it can be used (and I used it in this way) as an airspeed indicator when attached to the base bar of the hang glider.
Winds at just 2000 feet above means sea level were calculated by one of my weather apps to be over 50 knots (92kph). Many locations at elevations of this order and above experienced winds of this strength and more on this morning.
The wind was of sufficient strength while I was trying to take a photo of the wind gauge, that on more than one occasion I was blown back and had to take a backward step to stay upright. When the wind speed doubles, its force increases four fold, when it triples, the force increases nine-fold etc. So this 40 knot wind compared to a 10 knot wind had 16 times the force. It felt like it.
35-45 knot winds lashing Apollo Bay harbour and dunes. The sand I got in my eyes taking this video took two days to disappear.
Looking due east over the mouth of the Barham River as the gale force winds tore the tops off the waves, lifting water from the surface and turning whitewater into high speed smoking trails of spray. In small areas where the gusts are noticeably stronger the wind lifts more spray from the water. Spray blown from cresting waves during a gale is known as spindrift.
A marked area of spindrift offshore from Pt Bunbury.
Turbulent gale force winds, spindrift rising from the sea, shorebreak flattened by the wind, wave crests ragged and blown away, stormy seas to the horizon and a great crested tern soaring over it all. An adult great crested tern weighs only 275-370g. Its fine hollow bones and aerodynamically perfect array of feathers not only survive in this wild wind, but allow the bird to positively revel in it. This bird was not struggling at all in these conditions, and flew with its usual precision and purpose. What a delicate and wonderful counterpoint the presence of such a bird is to the mighty forces of the stormy ocean over which it flies.
There is a craypot buoy visible just right of centre and near bottom border of the image. This pot wasn’t checked while I was there. I wonder if crayfish have any idea there is a gale blowing above the surface of the water above them. I suspect they don’t. When swimming in rough water I often remind myself that it’s only rough on the surface. Crayfish could well do the same.
Little Henty Reef. This photo was taken from 2100m away on Pt Bunbury. Only small swell was breaking, but the spray was blowing downwind for hundreds of metres like white smoke streaming downwind from a bushfire. This spray consists of water droplets which have mass, which when blown off the top of a breaking wave would normally fall to the water surface close behind the wave. Streaming spray falls the same vertical distance in stronger winds, but in a 40+kt wind the spray travels much further horizontally while it is falling. Spray as shown here only occurs in very high winds.
Apollo Bay harbour in gale force winds. I suppose I should’ve taken a video to properly convey this fact. You’ll just have to take my word for it. An ocean swim after the wind eased
An hour or so after I measured the wind at Pt Bunbury at 41 knots, this was the scene at Tuxion beach looking north. I went for a solo swim to the north and back again (1000m). The wind was still strong, but because it was offshore at this end of the bay, such swell as was there was completely flattened. Whitecaps are not visible because the wind must travel some distance before whitecaps are formed. The stronger the wind, the shorter the distance it takes to create wind waves and whitecaps.
