The Lowdown

G’day, Rusty here, and I’ve been staring at the charts for Cowries all morning. It’s a bit of a slow burner for the next couple of weeks, but there’s a couple of windows that’ll get the heart rate up.

Right now, the surf is small and honestly, pretty ordinary. The combined swell energy is sitting at a moderate 223, and while the glassy conditions on Sunday morning are a blessing, that 3ft S’ly swell with a 9-second period is just not doing much. It’s a reef and point set-up here, so it needs a bit more oomph to really fire. You’ll see a few knee-high peelers, but you wouldn’t race out the door for it. The water temp is about average for this time of year, so no surprises there.

Monday morning offers another glassy window with a similar 3ft swell, but again, the energy is just 166 – it’s still a bit gutless. Through the middle of the week we drop even smaller, with heights barely cracking 2ft and a lot of cross-shore wind. Wednesday and Thursday afternoons have a clean offshore breeze (W’ly 15-20 km/h) but with only 2-2ft of swell on offer, it’s more of a longboard glide than a proper session. The period stretches out to 12 seconds on Thursday morning, which is a nice sign of some groundswell, but there’s no height behind it.

Now, if you can wait, the first real standout arrives on Wednesday the 9th of September. The morning is set to be a beauty – glassy conditions, clear skies, and a 5ft S’ly swell pumping in with a 10-second period. The combined energy jumps right up to 364, and that’s the best looking wave we’ve seen yet. It’s still a solid intermediate size, so not one for the grommets, but for everyone else, it’s game on. The swell is coming from the south, which is off the optimum ENE direction for this spot, but with those clean, glassy conditions, it’ll still offer up some long, workable lines.

And then, hold onto your board shorts – Thursday the 10th of September morning is the absolute pick of the entire forecast. We’ve got a 7ft S’ly swell with a 10-second period and a combined energy reading of 925. That’s a big, powerful pulse and it’s going to make Cowries a proper handful. This size is squarely in the expert-only zone; it’s going to be big, heavy, and demanding. But the wind is glassy from the SSE, so the face will be clean and inviting for those who can handle it. This is the blue-ribbon day – if you can sneak out for this morning session, you’ll be telling stories about it.

The week after settles back down into small to tiny surf with mostly onshore or cross-shore winds. The 13th and 14th of September offer a tiny 2ft NE swell but with a very short 6-second period, it’s barely a ripple. It’s a long gap of average to poor conditions after that Thursday cracker.

Bottom line: The first week is a write-off unless you’re desperate to paddle. Wednesday the 9th morning is good, and Thursday the 10th morning is an absolute standout – get on it. After that, the tank runs dry again.

Rusty.

Information about the Cowries Surf forecast

The above surf forecast table for Cowries provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cowries can be found by selecting the local surf guide option on the grey menu. Our Cowries surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Cowries) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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 Cowries 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.

Cowries is 10 km (6 miles) from the city of Port Kembla. If you plan a holiday in Illawarra, look for hotels and other accommodation in Port Kembla. Port Kembla has rooms for a wide range of budgets as well as car hire and transport links.
