The Lowdown

Alright, surfers, Rusty here. Let’s chew the fat on the next couple of weeks.

It’s looking like a slow burn for a while. The next seven days are filled with small, rideable waves, but there's nothing that's going to fire you up. The real deal is that big pulse of southwest groundswell at the end of the forecast period—that’s the one to keep tabs on.

Let’s start with today. Wednesday morning, it’s a bit ordinary. Swell is small at 3ft from the south with a weak to moderate energy (218), but it's clean with a light cross-off breeze. It’s surfable, but nothing to write home about. The afternoon, the wind swings offshore and cleans it up, but the swell backs off to 3ft (145). Just small, clean lines.

Thursday is much the same. Morning has clean, 3ft surf from the south (173) with light offshore winds, but the afternoon gets a touch lumpy with a cross-onshore wind. Nothing special.

Friday is your best bet for this first stretch. We get a glassy morning with the swell holding at 3ft from the south (203). It’s not big, but a glassy Cowries with a little push is worth a look. The afternoon, the wind goes cross-on and it gets messy.

The weekend is a washout. Saturday has some energy building to a 6ft swell (427), but conditions are marginal and the wind is a cross-off mess. It’s just bumpy. Sunday and Monday look worse, with more onshore wind and chop. The swell is there, but the quality is poor.

We get a little reset on Tuesday, the 19th. The morning is clean with a light cross-off breeze and a 4ft south-angled swell (273). Expect good conditions, but the energy is still moderate. Then, on the morning of Wednesday, the 20th, we get another glassy window with a 5ft easterly swell (308). That also looks like a fun one before the winds shift onshore in the afternoon. These are the two little gems in the middle of the run.

Then there’s another quiet patch. From the 21st through the 24th, the wind is just not your buddy, with a lot of cross-onshore and fresh breezes. The waves are there, but the quality drops right off. It's a frustrating stretch of ordinary conditions.

Now, for the good stuff. The outlook for the 25th looks promising, with strong offshore winds and a clean 4ft ENE swell (280) rolling in. That will be a fun day. The morning of the 26th is the standout, but it’s a double-edged sword. It calls for a massive 13ft groundswell from the south, with a huge energy reading (2874), but it’s flagged as being too big for this break. That’s a powerful, dangerous ocean, and only the experienced should even think about it. The direction is from the south, which is not the optimum for Cowries, but at that size, it will still wrap in with authority.

So, in summary, the next week is about finding those clean windows. The second week holds more promise, leading up to a potentially giant but hazardous swell on the 26th. Keep your eyes peeled for that one.

Rusty out.

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.
