The Lowdown

Alright, this is Rusty, and I’m looking at the next 16 days for the Cowries. Straight up, this is a stop-start kind of outlook. We’ve got some decent windows, but there are some real flat spells, so don’t expect a run of non-stop action.

The first real pulse of surf hits us on Friday afternoon, July 31st. We’re looking at a 7ft south swell, with a period of 9 seconds, so it’s a bit of a windswell, but it’s got some energy behind it – the combined energy reading is 1206 (moderate wave energy). The wind is a cross-offshore from the south at 9 mph, keeping things pretty clean. The water temp is sitting at 65°, which is about 2° warmer than normal for this time of year, so it’s a touch on the warm side, but nothing too wild.

Now, the standout for my money is Saturday morning, August 1st. The swell drops a touch to 5ft from the SSE, but it’s still a 9-second period. The real winner here is the light breeze from the south at 6 mph, making for clean conditions. The water is still that slightly warmer than average temp. This is the pick of the first few days.

Then we get a real treat. Saturday afternoon, August 1st, goes glassy. A 5ft SSE swell, combined energy of 316, and the wind turns to a light 3 mph from the NE. That’s glassy. It’s going to be smooth as, perfect for a long session. If you can get out there, that’s the one.

The next few days, from Sunday the 2nd into the middle of the following week, are a bit of a mixed bag. We get a solid 5ft, 12-second groundswell on Sunday morning, with a cross-shore wind, but the energy is moderate (666). The wind swings around and gets strong on Sunday afternoon, making it messy. Monday and Tuesday of the 3rd and 4th are small, with the swell dropping to 3ft and then 0.7ft. The wind is offshore, but there’s just no push.

We get a bit of a second wind mid-week. Wednesday morning, August 5th, has a 3ft south swell with a clean offshore wind from the west at 6 mph. The energy is low (210), but it’s surfable. Thursday morning, August 6th, is another glassy one – a 5ft south swell, 8-second period, with a light southerly breeze. That’s a solid option for a fun, small-wave session.

The best quality of the whole forecast, in my opinion, is Friday morning, August 7th. A 5ft, 9-second SSE swell, combined energy of 401, and it’s dead calm. Glassy. The sets will be a bit more consistent. It’s a real treat.

After that, it’s a slow fade. The second week, from August 8th onwards, is mostly small to flat. The swell drops below 3ft, and the wind is often onshore or cross-on. We get a brief window of offshore wind on Monday the 10th, but the swell is only 1ft and 2ft, so it’s more of a paddle than a surf. The energy drops to really low numbers, like 59 and 90. There’s a pocket of clean, glassy conditions on Thursday morning, August 13th, but the swell is just 2ft from the east. It’s a long-period swell (11 seconds), so it might wrap into the point, but it’s a gamble.

Overall, the first week is the go. Lock in Saturday afternoon, August 1st, and Friday morning, August 7th, for the cleanest, most fun waves. The rest is a bit of a waiting game.

This is Rusty, signing off.

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.
