The Lowdown

Alright, Rusty here, looking at the surf for the next couple of weeks.

To be honest, the first week or so is pretty flat. We’ve got small, messy swells and mostly onshore or cross-onshore winds that just aren't doing us any favours. You’ll be looking at a lot of small, weak, and choppy conditions, so honestly, don’t bother paddling out for most of it. There's a gap of real quality right through until the end of the month.

Then, hang on to your board. Wednesday the 26th of August is looking like the real standout. We get a solid jump in size with a 7 ft swell at Cowries from the south. That’s some proper push with moderate wave energy (727) and the wind is offshore from the southwest. That means clean, lined-up waves. It’s still a reef and point setup, so with that size, you’ll want to be on your game—it’s not for beginners anymore. The water temp is running about 65°, which is pretty average for this time of year, nothing out of the ordinary.

The following Wednesday afternoon, the swell sticks around at 7 ft, but the wind gets a bit stronger from the WSW, still offshore but punchier. The wave energy jumps right up to 1171, so there’s plenty of grunt in the water. That’s a session for the experienced crew only.

After that, things drop off again. The 29th of August Saturday morning shows another pulse of 6 ft from the northeast with clean offshore winds, so that’s worth a look. The swell energy is moderate at 399, and that’s about as good as it gets for the second week. The rest of that week sees a bunch of average conditions, mostly side-offshore or glassy mornings but with smaller, weaker swell that just doesn’t have the same power.

So, if you’re waiting for the good stuff, it’s all about the 26th and 27th of August at Cowries. Clean, solid south swell with offshore winds. That’s the one.

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.
