The Lowdown

Righto folks, Rusty here. Let’s have a proper look at what’s coming down the pipe for Cowries over the next couple of weeks. We’ve got a bit of a slow start, but there’s a couple of windows that’ll get the heart rate up.

The immediate forecast is pretty quiet. For the first few days we’re looking at some south swell but the quality is just not there with the wind states we’ve got. Thursday the 10th has a solid 8 ft swell from the south with a 10-second period, but that cross-off wind is making it a marginal affair. The combined swell energy is strong at 2160, so there’s plenty of water moving, but it’s not coming together nicely. Water temps are about average for the time of year, nothing wild. Friday and Saturday drop off in size and the wind turns cross to cross-on, so it’s a bit of a write-off for good waves.

We hit a real quiet patch from Sunday the 13th all the way through to Tuesday the 15th. Swell drops under 3 ft and the wind is predominantly cross-on or onshore. This is a few days where you’re better off leaving the board in the car.

Now, there’s a little glimmer Wednesday the 16th morning. We get a clean 5 ft swell from the south-southeast with a light cross-off breeze. The combined energy is moderate at 439. It’s not huge, but it’s clean and surfable. That’s the best we’ve seen for a while. The afternoon turns cross-on again though, so get out early.

Another dry spell hits from Thursday the 17th to Monday the 21st. The swell is inconsistent, and wind is mostly cross-on or onshore, with a fresh breeze making things lumpy. The morning of Friday the 18th has a tiny 2 ft swell and glassy conditions, but it’s barely a ripple.

Then things get interesting. Saturday the 19th morning, the models are showing a big pulse of 10 ft south swell with a 10-second period. The combined energy is 2591, very strong. Now, that’s a powerful swell, and for a reef and point break like Cowries, that could be pumping. But the wind is a gentle cross-on breeze, so it’ll be a bit bumpy. This is one for the experienced crew only – 10 ft is big and not for beginners. It’s a standout in terms of size and power, but the wind keeps it from being perfect.

The tail end of the period looks promising too. Sunday the 20th afternoon has a clean 3 ft south swell with a 11-second period and offshore wind. That’s a proper little session with clean lines. Then Thursday the 24th afternoon looks glassy with a 5 ft south swell at 11 seconds, combined energy at 588, and glassy conditions. That is a standout for sure – clean, solid groundswell. Finally, Friday the 25th morning has 4 ft south swell with a clean cross-off breeze.

To be honest, the standout sessions are the Wednesday the 16th morning for a clean small wave, the Thursday the 24th afternoon for a glassy, solid swell, and the Friday the 25th morning for another clean one. The big 10 ft on the 19th is there but the wind holds it back a touch.

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.
