The Lowdown

Alright, let me break this down for you. It’s Rusty here, and we’re looking at a pretty quiet stretch ahead for Cowries.

The next 16 days start off slow, real slow. For the first few days, the swell is small and the wind is messy – mostly cross-on, keeping things choppy and uninviting. The best you can hope for early on is a brief spike Tuesday afternoon with a 5ft swell from the NE, but it’s mixed with light rain and cross-shore wind, so it’s more of a “maybe if you’re desperate” situation than a proper session.

Thursday the 27th morning is where things first look tidy. We get a glassy morning with 5ft swell from the S, period around 8 seconds, and clean conditions. The combined energy is moderate (353), so there’s a bit of push. This is the first real standout in the window – clean, small enough for beginners, but still fun if you’re on a log. Keep an eye on the afternoon though, as the wind swings cross-on and kills it.

After that, we go back to small, mediocre surf through the end of August and into early September. There’s a morning here and there with glassy conditions, like Friday 28th morning with a small 3ft SSE swell and long 11-second period, but it’s weak in energy (254) – just enough for a longboard cruise. Sunday 31st morning has a very long 19-second period groundswell hitting, only 2ft, but glassy; that’s a real weird one – tiny but perfect lines for a point break, but at a beach setup that long period might make it close out. Still, if you’re patient and picky, it could offer some fun.

The tail end of the window shows some promise. Saturday 5th September morning is clean with 2ft S swell, but it’s short period (6 seconds) so weak and weak energy (71). Then Sunday 6th September morning steps it up: 4ft S swell, 11-second period, clean cross-off wind, moderate energy (292) – that’s the best of the second week. It’s still a week away, so promising but not locked in.

Overall, the only true standout in the whole 16-day run is Thursday morning the 27th of August – glassy, clean, decent size for the area, and moderate energy. The rest is mostly small, ordinary, or wind-affected. Crowds? Cowries gets them sometimes, so if you hit that Thursday morning window, expect some company.

No kite surfing calls here – the swell just isn't strong enough or consistent enough, but the beach setup could handle it if the wind cooperates.

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.
