The Lowdown
G’day, Rusty here, lookin’ at the Cowries stretch over the next couple of weeks. This is a reef and point setup, fairly exposed to the swell, and it’s an ENE optimum direction. The water’s runnin’ a touch warmer than normal for this time of year, sittin’ at 66°, so that’s a nice little bonus.
We’ve got a bit of a gap to start, with no real surf on offer until this Saturday morning, July 25th. That first session is a highlight though. Saturday morning brings a clean 5 ft S swell, period 11 seconds, with a light cross-off breeze from the W at 6 mph. The wave energy is moderate (449), and the water’s a touch warmer than average. It’s a clean, glassy mornin’ – perfect for a beginner-friendly paddle at Cowries. The swell direction is S, but the optimum is ENE, so it’s not the perfect angle, but the conditions are so good it’ll still be a fun wave. Crowds can pop up there sometimes, but it’s worth it.
Saturday afternoon goes glassy with a 4 ft S swell, lower energy (279), but still clean. Sunday morning, the 26th, is another cracker with a 6 ft S swell, period 11 seconds, and a light offshore from the SW at 3 mph. The energy is strong (660), and it’s clean again. For a beginner, 6 ft is gettin’ up there, but it’s still manageable. The swell direction is S, again not the optimum, but the offshore wind makes it clean.
Sunday afternoon turns a bit cross-on, and the swell drops to 5 ft, only marginal. Then we hit a dry spell from Monday, the 27th, through to Wednesday, the 29th – the swell dips to tiny, weak stuff, poxy energy, and the wind’s all over the shop. Not worth paddlin’ out.
Thursday morning, the 30th, sees a big jump in energy (1543 – strong) with a 8 ft S swell, period 9 seconds. That’s big for beginners and only for the more experienced crew. The wind is cross-off from the SSW at 12 mph, keepin’ it clean, but the swell is a bit raw. The period is short, so the waves might be a bit lumpy. Thursday afternoon and Friday are still cross-off, with 5 ft to 6 ft, but the energy is lower and conditions are only marginal.
The first week of August starts quiet, with Saturday morning, the 1st, glassy but tiny at 3 ft. Then from the 2nd to the 4th, it’s all small, weak swell and average conditions. Then, on Wednesday morning, August 5th, we get a standout. A 7 ft SE swell, period 12 seconds, with an offshore wind from the W at 3 mph. The energy is massive (1494) – strong. This is a long period groundswell, and for a reef and point like Cowries, that’s a dream. The swell direction is SE, which is closer to the optimum ENE. This is a clean, powerful, long-period swell – only for the experts at this size, but it’s a ripper. The afternoon goes cross-on, so grab the morning.
The 6th and 7th have good clean mornings with 4 ft to 5 ft SE swells, light winds, and moderate energy. Then on Saturday, the 8th, it’s a big 10 ft SSE swell, period 8 seconds – that’s huge, short period, and only for the brave. The energy is 1080, strong, but the wind is cross-shore, makin’ it messy. Sunday morning, the 9th, is a beauty though: 7 ft SSE swell, period 10 seconds, with a light cross-off from the WNW. The energy is 1001, strong, and the waves are clean. This is a solid, high-quality option for the experienced crew.
The absolute best on offer is that Wednesday morning, August 5th, with the long period groundswell and offshore wind – that’s the one to circle. The Sunday morning, the 9th, is a close second. For the beginners, stick to Saturday morning, July 25th, and Sunday morning, the 26th, before it gets too big.

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.
