The Lowdown
Alright, grab your wetsuit and let’s have a look at what’s on the cards for Cowries over the next couple of weeks.
First off, I’ll be straight with ya—the next seven days are looking pretty damn flat. We’ve got a lot of small, weak swell and iffy winds, so don’t get your hopes up for anything decent. It’s gonna be a waiting game. We’re looking at a serious gap in any real surf from now until the end of the first week of September. You’re better off sorting your gear, maybe doing a few laps of the point on the paddleboard, because the waves just aren't there.
The only thing with a bit of life early on is a smallish pulse on the 28th of August, Friday morning. We’re talking about 5ft of south-southeast swell with an 11-second period, so it’s got a little bit of push. The wind is light and cross-off from the southwest, which should keep the reef and point pretty clean. It’s not going to be epic, but it’s the most surfable you’ll see for a few days. You might get a few fun ones if you’re not too picky. The energy is moderate at 597, so there’s something to work with, but it fades fast.
After that, it just dies. We’re talking sub-3ft dribble for days on end. The 31st of August has a long-period groundswell but bugger all size—only 2ft to 3ft. The 1st and 2nd of September are in the same boat, just gutless and weak with poor conditions. The water temp at the start of this forecast is around 64°, which is about average for this time of year, so nothing crazy there.
Now, for the good news. If you can wait, there’s a proper pulse of swell lined up for the 7th and 8th of September. This is the standout of the whole period. It’s a long way off, so don’t book the day off work yet, but the models are showing a significant drop in the charts.
On the 7th of September, we see the swell jump to 10ft from the south-southeast with a 10-second period. The energy is strong to very strong at 1709. The wind is howling offshore from the west-southwest, which will keep it clean, but this size is only for experienced surfers. This wave is over 8ft, so it's expert territory, and the reef will be working hard.
Then the real gem is the morning of the 8th of September. The swell is still a solid 10ft from the south, but the wind goes totally glassy. The energy jumps up to 2840, which is very strong. This is the one to circle on the calendar—excellent conditions for those who know what they're doing. It’ll be heavy and powerful, a proper reef break.
The swell backs down through the 9th, dropping to 5ft, and the winds start to get a bit messy. The rest of the run looks like it fizzles out again, with some long-period but tiny swell early in the second week. The 11th has some clean conditions but only 2ft of swell, so it’s a flat spell again.
So, to wrap it up: the first week is a washout, the 28th is a small teaser, and the real show is on the 8th of September if you’re a competent surfer. It’s a long way out, so we’ll have to see how it shapes up, but it’s got the potential to be the best waves of the whole forecast. Keep an eye on it.
Later, 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.
