Swanbourne Beach Surf Forecast and Surf Report

Alright, let’s get into it.

We’ve got a solid run of swell heading our way at Swanbourne Beach, but it’s going to be a bit of a wild ride. The water’s sitting at 63°, which is a bit colder than normal for this time of year, so don’t forget the rubber.

The first sniff of decent surf is Tuesday morning, August 4th. We’re looking at a 6ft WSW swell with a very long period of 19 seconds. That’s groundswell, and it’s packing some serious energy (2333). The wind is onshore from the west at 12 mph, so it’s going to be a bit messy. This one’s for the experienced crew only, and even then, it’s marginal. The tide might be playing games too.

Tuesday afternoon clears up, but the wind goes cross-onshore from the WSW at 9 mph. The swell bumps up to 7ft, still a long period of 17 seconds, and the energy is climbing (2627). Still, it’s choppy and marginal.

Wednesday morning, August 5th, is a tease. The wind swings light from the north at 6 mph, giving us a cross-shore breeze. The swell is 8ft from the WSW, period 16 seconds, energy 2895. It’s still a bit bumpy with crossing ripples, but it’s getting there. Then Wednesday afternoon – this is the first real standout. The wind is light onshore from the west at 6 mph, but the swell jumps to a solid 10ft, period 16 seconds, and the energy is roaring (3951). The model says the wind and tide are favorable, but honestly, 10ft at Swanbourne is a beast. For experienced surfers only. This is the best on offer in the first week.

Thursday and Friday (August 6th and 7th) see the swell hanging around 8ft, but the wind is mostly cross-onshore or onshore, and it’s chopped up. Friday afternoon gets ugly with a 19 mph westerly and rain. A big skip.

The weekend (August 8th-9th) is a write-off for paddle surfing. Swell is huge – 15ft on Saturday, 10ft on Sunday – but the wind is howling. Saturday has a 28 mph SW cross-onshore, and Sunday sees a 16 mph onshore. This is kite-surfing territory, not for a board. The energy is massive (7612 on Saturday afternoon), but it’s a mess.

Monday, August 10th, offers a glimmer. A 8ft SW swell with a 14-second period, and a clean cross-offshore breeze from the SSE at 12 mph. The energy is 2691. It’s still a bit marginal, but the clean wind is a big positive.

Now, the second week has a couple of absolute gems. Tuesday morning, August 11th, is the standout of the whole 16-day window. The wind goes glassy – a perfect 3 mph from the SW. The swell is a very surfable 6ft from the WSW, with a 15-second period, and energy at 1611. The model says it’s excellent for experienced surfers. This is the one to circle on the calendar. Clean, lined-up, and all yours if you’re good enough.

Wednesday morning, August 12th, is another beauty. A light cross-offshore breeze from the NNE at 6 mph, a 6ft WSW swell, 16-second period, and energy of 1743. Clean conditions again. Thursday morning, August 13th, follows the same pattern with a 7ft swell and clean cross-offshore wind. These three mornings are the highlights of the second week.

The rest of the second week (August 14th-16th) drops off a bit. Swell stays around 6ft to 7ft, but the wind is mostly cross-shore or cross-onshore, and the energy fades. Not terrible, but not the standout sessions.

Then, from August 17th onwards, the swell pumps up again but with strong onshore winds, making it poor for surfing. Tuesday, August 18th, has a massive 15ft swell with 17-second period and energy over 10,000 (10563), but the wind is cross-onshore. It’s just too big and messy for a safe paddle.

So, to wrap it up: Wednesday afternoon, August 5th, is the big-wave call for the brave. But the true, clean, quality standout is Tuesday morning, August 11th. Glassy, good-sized swell, and long period. Don’t sleep on it.
