The Lowdown

Alright, let’s get into it.

The next couple of weeks are looking pretty full-on for Dongara-Port Denison. We’ve got a solid run of SW groundswell on the cards, but the wind is going to be the big player here. It starts a bit rough, cleans up for a few days mid-week, then gets messy again before a final window of hope further out.

Monday the 10th is a write-off. There’s a solid 8ft to 10ft of SW swell, but the wind is howling onshore and it’s raining. The ocean is going to be a washing machine, not a surf. The energy is strong (3062-5561), but it’s all for nothing. You’re better off doing anything else.

Now, Tuesday the 11th is where my heart starts beating a little faster. We’ve got 13ft of SW swell and the wind swings around to the ESE, giving us a clean cross-off. The energy is pumping at 8486. This is a big day, too big for the faint-hearted. This is proper, experienced surfer territory. The period is a solid 16 seconds, so it’s got that long-period groundswell push. It’s going to be powerful out there.

Wednesday the 12th and Thursday the 13th mornings are the standouts from this first pulse. The swell has backed off to a more manageable 8ft to 10ft, but the wind is light and offshore from the East. That’s the recipe for some proper clean, glassy waves. The energy is still strong (2924-4272), and with that 15-second period, the lines should be well-defined. These mornings are the ones to circle. The crowds are "sometimes" a factor, so with waves this good, expect a few other locals out there.

Friday the 14th still has excellent conditions, with a moderate offshore wind and clean 8ft surf. Solid, but the magic of the previous two days might be just a touch less.

The weekend, the 15th and 16th, sees the swell ease off and the winds get a bit more variable. It’s not terrible, but it’s not a patch on the mid-week. The energy drops right off too (933-1838). It’s more of a smaller, weaker, and less consistent bank of swell.

Then we get a bit of a pulse again on Monday the 17th, with 8ft of long-period (19 seconds) SW swell, but the wind is cross-onshore. It’s a bit of a shame, as that long period would have been something else. The energy is up (4889-5066) but the surface will be a bit bumpy.

Tuesday the 18th and Wednesday the 19th are rough. The wind is onshore and really cranking, especially Wednesday with a strong breeze and 15ft of swell, energy up at 9205. That’s a full-blown storm surf. The water will be a mess. This setup, with that much swell and wind, is looking far more interesting for the kite crew than for us paddle surfers.

A week from now, on Thursday the 20th, there’s a light at the end of the tunnel. The wind drops right out in the morning, going cross-offshore, and we’ve still got 10ft of SW swell with a 15-second period. The energy is strong (4245). This could be a fantastic morning, another one for the experienced crew. It’s far out, so treat it as promising but not set in stone.

The following week, the 21st and 22nd, looks like more wind and mess, with energy levels dropping. Then, on Sunday the 23rd, the East wind comes back in as a moderate offshore. The swell is a smaller, 8ft, but it’s clean and the energy is moderate (2090). Not as big or powerful as the earlier days, but it could still be a fun session.

So, the pick of the bunch is the mornings of Wednesday the 12th and Thursday the 13th. Get on it then. The water is around average for this time of year, so a steamer is your friend, but nothing extreme.

Alright, that’s the wrap from me. Keep an eye on the buoys and the sky.

Rusty.

A general guide to surfing at Dongara-Port Denison can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Dongara-Port Denison may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
