The Lowdown

G’day, Rusty here. Let’s have a look at what’s coming up for Dongara-Port Denison. The next couple of weeks are going to offer some solid opportunities, but you’ll need to pick your days carefully. The standout is going to be Tuesday the 18th, when a real beauty rolls in.

Alright, we kick things off this Saturday, the 15th of August. The morning’s looking pretty tidy with a clean 7 ft SW swell, period of 14 seconds, and a light cross-offshore breeze from the ENE at 6 mph. The combined swell energy is sitting at 1736, so there’s a decent amount of push. It’s excellent for experienced surfers. The water’s a bit colder than normal at 65°, with a -3° anomaly – that’s notably cooler than usual for this time of year. Sunday the 16th, the morning drops to a smaller 4 ft but with a long 16-second period, and the wind is a fresh 19 mph NE cross-off, keeping it clean. The energy is still moderate at 1212, but honestly, the size is marginal. However, Sunday afternoon is a ripper: a clean 7 ft SW swell with 16 seconds, a light ENE cross-off at 6 mph, and energy bumps up to 1989. That’s a good session for the experienced crew.

Now, Monday the 17th is a write-off. Rain, onshore westerly wind, 6 ft to 8 ft SW groundswell, and the energy is high – 2873 and 3639 – but the conditions are poor. It’s messy and lumpy. Save your energy.

The real standout is Tuesday morning, the 18th of August. This is the one. You’ve got a clean, glassy 12 ft SW swell with a 16-second period. The combined swell energy is a whopping 6545, which is very strong. The offshore wind is glass, absolutely no breeze. This is exceptional surf, but it’s for expert surfers only – that size is serious and powerful. This reef break (Dongara-Port Denison) will be cranking. Tuesday afternoon stays big at 12 ft but shifts a touch more WSW and the cross-onshore wind makes it choppy.

Wednesday 19th through Friday 21st sees the swell settling but still solid. Wednesday morning is a clean 8 ft SW swell, 16 seconds, with a light cross-off from the ESE. Thursday morning is similar: 10 ft SW, 16 seconds, clean. Friday morning, 8 ft SW, 15 seconds, with a gentle offshore. All excellent for experienced surfers. Crowds are sometimes a factor, so keep that in mind.

The second week starts to look a bit more inconsistent. Saturday 22nd has a clean 7 ft SW swell in the morning, but the energy is dropping. Sunday 23rd is similar, with a 8 ft SW swell and light wind. By Monday 24th, it fades to a 5 ft SW swell, and the cross-onshore wind brings in choppy conditions. There’s a stretch from Monday 24th through to Wednesday 26th where conditions are marginal and the energy is weak – between 783 and 1094. Thursday 27th morning shows a 5 ft SW swell with a very long 18-second period, light cross wind, and energy back up to 1529 – a bit more promising, but still a touch messy. Friday 28th morning is another good window: a glassy 7 ft SW swell with 18 seconds, energy of 2906, clean and crisp. After that, Saturday 29th goes back to small and choppy. Sunday 30th has a big, onshore 7 ft to 10 ft SW swell, but the onshore wind ruins it. That setup looks more interesting for kite surfing than paddle surfing.

Overall, the best call is Tuesday the 18th at Dongara-Port Denison – that big, glassy, powerful groundswell is the highlight. Friday the 28th morning is a solid backup for the second week, but keep an eye on it as long-range forecasts can shift.

Rusty.
