The Lowdown
Alright folks, Rusty here. Let’s look at what’s coming up for Cowries. It’s a bit of a slow start, but there’s a couple of windows that could be worth paddling out for. The water is sitting about average for the season, with temps around 65°, just a touch warmer than normal for this time of year.
The first few days are pretty flat and messy. Friday the 17th and Saturday the 18th are a write-off – tiny, weak swell with poor conditions. The energy is low, in the double digits or barely cracking 100 (18 to 131). Not worth getting the wetsuit wet.
Sunday the 19th brings a bit more life, with a 6ft swell from the ENE, but it’s a cross-shore wind and the conditions are marginal. The swell energy is strong (1000), but the quality just isn’t there for a good session. Monday the 20th is similar, with a 5ft ENE swell, but the wind swings cross-on and it gets choppy in the afternoon.
Now, Tuesday the 21st is the first real standout. We’ve got a 4ft ENE swell, but the real magic is the wind. It’s glassy – dead calm – both morning and afternoon. The energy is moderate (374), and the wave comment says “expect good surf conditions.” For a reef and point break like Cowries, that glassy water with a 4ft swell is going to be clean and fun. The period is 10 seconds, so it’s a decent groundswell with good shape. Keep in mind, crowds are possible here, so get there early.
After that, Wednesday the 22nd drops off a bit, and Thursday the 23rd is small with offshore winds, only surfable but nothing special. The energy is weak (117).
Then we get another proper window on Friday the 24th. The morning looks clean with a 5ft swell from the S and a light offshore breeze. The energy is moderate (304), and the wind is offshore, so Cowries should be well-shaped and tidy. The period is only 8 seconds, so it’s a shorter-period wind swell, but with that offshore wind, it’ll still be a fun, rippable wave.
The rest of the period into the end of July and start of August is mostly small, with occasional clean mornings but nothing that jumps out. The energy stays in the double- or triple-digit range, mostly under 300. The only other highlight is the morning of Saturday, August 1st. We’ve got a 3ft SSE swell with a 12-second period and a gentle offshore wind. The energy is moderate (275), and the wave comment says “expect good surf conditions.” It’s a small but clean day, perfect for a longboard.
So, the best on offer is that glassy Tuesday the 21st. The standouts are Tuesday the 21st for the glass, and Friday the 24th for the clean offshore wind with a bit more size. The later window on Saturday, August 1st is a promising but smaller option.
Signing off, 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.
