The Lowdown

Alright, Rusty here, talking in feet and miles per hour for the Americans.

The next couple of weeks are going to test the patience a bit here at Cowries. This spot is a reef and point break, pretty exposed out there, and it takes a south swell best. But the next few days? Honestly, it’s looking flat or messy. The water temp is sitting around 64°F, which is pretty much average for this time of year, nothing weird going on there.

We’re looking at a dry spell straight off the bat. From Tuesday the 1st right through to Friday the 4th, the swell is tiny, mostly under 3 feet with a short 10-second period, and the combined energy is barely getting into the low hundreds (174 at best). The winds are either cross-on or side-off, nothing to get excited about. It’s basically a no-go for a good paddle. You’d honestly be better off on a kite if the wind picks up, because the wave quality is just not there for a surfboard.

Saturday and Sunday mornings improve slightly. On Sunday the 6th morning, we see a glassy morning with 4 feet swell from the south and the energy jumps to 335. That’s the first proper window for a cleanish wave, but it’s not a standout.

The next few days slide back into the ordinary with mostly cross-on winds and messy lumps. That is, until Wednesday the 9th afternoon. The swell jumps to a solid 10 feet from the south at 11 seconds, and the energy rockets to 3057. The wind is cross-off and clean, but the surf quality note calls it marginal. That’s a big swell that might be too much for the shape of this break.

Now, the real action is the standout window. Thursday the 10th morning is just too big. The finder is telling us the swell is predicted to be too big for this break at 13 feet. That’s expert only, and even then, it's messy.

Friday the 11th morning is the one to circle. We’ve got 10 feet of south-southeast groundswell with a very long 13-second period, and glassy conditions. The combined energy is a massive 3070. That is some serious power. The sets will be long and waiting, but the shape on a point like Cowries should be phenomenal. It’s an excellent condition for experienced surfers. The afternoon holds similar glassy conditions with 10 feet swell at 12 seconds (2325 energy). This is hands down the best on offer—a true, high-quality, big-wave day.

Saturday the 12th morning sees another huge pulse, 12 feet at 11 seconds (4257 energy), but it’s blowing hard from the SSW at 19 mph, making it cross-off and likely tricky. That’s also a "too big" call for the break. The following days drop back into the 3 to 7 feet range with mostly cross-off winds, which is surfable but nothing compared to that Friday.

We also have a nice little window on Monday the 14th morning with 5 feet of east-southeast groundswell at 11 seconds, glassy. That’s a solid, clean option for a quieter session. Tuesday the 15th afternoon looks good too, picking up to 6 feet from the south with offshore and clean winds.

So, overall: don’t bother with the first week. The one true standout is Friday the 11th – get on it if you’re an experienced surfer. The Monday the 14th morning is a solid secondary option for cleaner, more manageable waves. The rest is for the kites or a rest day.

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.
