The Lowdown

G’day, Rusty here. We’ve got a solid run of south-west groundswell lined up for Dongara-Port Denison, and it’s mostly for the experienced crew. This is a reef setup, exposed to the west, and when it gets clean, it’s a proper wave. Water temps are about average for the time of year, so no surprises there.

The big news is a strong run of swell starting Wednesday the 12th on the morning session. We’re talking 10 ft SW groundswell with a 16-second period, so plenty of energy in the water (3876 combined energy). With an easterly offshore breeze around 9 mph, it’s going to be clean and lined up. This one’s for experienced surfers only – it’s big, powerful, and the reef won’t forgive a mistake. That Wednesday morning is a standout.

Thursday morning the 13th keeps the quality high: 8 ft SW swell, 15-second period, and an offshore ENE breeze at 9 mph. The energy is still strong (3686), and the waves will be well-shaped. It’s still very solid, so keep your wits about you.

Friday morning the 14th is another beauty. 8 ft SW, 16-second period, and a clean offshore E wind at 12 mph (3624). The consistency is there, and the sets will have push. Again, it’s waves for competent surfers who can handle a solid reef break.

Saturday morning the 15th eases a touch to 7 ft SW, 14-second period, with a cross-offshore ENE breeze (1736 energy). Still clean and fun, but the size drops enough to think about stepping down to a smaller board.

Sunday the 16th is a mixed bag. The morning is a bit weaker at 4 ft, but the afternoon turns glassy – zero wind – with 7 ft SW at 16 seconds (2185 energy). That afternoon session is clean and inviting, but the bigger pulse is back.

Monday the 17th goes ugly with onshore winds and messy conditions. Skip it.

Tuesday the 18th morning is a ripper: 10 ft SW, 16-second groundswell, and a light offshore NE breeze (4588 energy). It’s going to be big, clean, and pumping. Another standout morning for those who can handle it.

Wednesday the 19th is onshore and lumpy. Not worth it.

Now, here’s the real gem: Thursday the 20th morning. 12 ft SW, 16-second period, with a light cross-offshore NNE breeze. The combined energy is massive (6963), and it’s described as exceptional surf for experts. This is the best on offer – a proper, heavy, grinding reef wave with clean conditions. Mark it on the calendar.

Friday the 21st is a write-off with fresh onshore gale-force winds and rain. Stay home.

Saturday the 22nd morning sees a huge 13 ft SW swell, 19-second period (10892 energy). That’s very long-period groundswell and it’s going to be powerful. The wind is cross-shore, so it’ll have some bump, but for experts, the size and energy will be there. Not a beginner’s day.

From Sunday the 23rd onward, the swell backs off and the winds turn onshore or cross-onshore, making things lumpy and choppy. Monday the 24th is rain and strong winds – poor. Tuesday the 25th drops to 5 ft with clean conditions but low energy (786). Wednesday the 26th and Thursday the 27th mornings offer cleaner cross-offshore breezes with 7 ft to 8 ft SW swell (1725 to 2281 energy), which will be tidy but not the highlight of the run.

So bottom line: if you’ve got the skill, the early mornings from the 12th through the 20th are where it’s at, with Thursday the 20th morning being the standout. It’s a reef, crowds are possible, so get in early.

Rusty.
