The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer at Cowries for the next couple of weeks.
First up, we’ve got a bit of a quiet start. Wednesday the 29th is a write-off with hardly any swell and poor conditions, so don’t even bother. The real action kicks off on Thursday morning the 30th. Thursday morning sees a clean 5 ft southerly swell with a light cross-offshore breeze. The combined energy is moderate (333). Not massive, but a fun, clean wave for a beginner-friendly reef and point setup. The water is sitting at 66°, which is a touch warmer than usual for this time of year. Thursday afternoon gets a bit messy with a cross-shore chop, so get it early.
Friday the 31st keeps the good times rolling with a solid 6 ft southerly swell in the morning. The wind is a light cross-offshore, keeping things clean, and the energy is up (658). Friday afternoon holds up well too, with a 6 ft SSE swell. This is a nice run of surf. Crowds are possible here sometimes, so keep that in mind.
Now, the standout of the whole forecast is Saturday morning, August 1st. The swell is a clean 5 ft from the SSE, but the wind is glassy. Absolutely flat calm. The wave energy is still moderate (408), but that glassy surface will make for some of the cleanest, most user-friendly waves you’ll see. This is the best on offer for the first week. Saturday afternoon turns onshore, so again, morning is the move.
Sunday the 2nd is marginal, with a cross-shore wind and a dropping swell. Monday and Tuesday, the 3rd and 4th, are pretty flat with weak energy (109 or less). A couple of small days to recharge.
Then we get a second pulse. Wednesday morning the 5th brings back a clean 5 ft south swell. Thursday morning the 6th is bigger, with a 6 ft south swell, short period (8 seconds), but clean with a light cross-offshore. The energy jumps up to 769, which is solid. This is a good, punchy morning session.
Friday the 7th is another clean morning with 6 ft from the SE, but the energy is high (836). The real standout of the second week is Saturday morning, August 8th. Glassy conditions again, with a 5 ft SE swell. The period is a nice long 12 seconds, which means proper groundswell energy. The combined energy is strong (698). This is a beautiful, clean dawn patrol. That long period will make the waves at this reef and point setup really stand up and offer some nice lines. Saturday afternoon gets chopped out by the onshore, so be there at sunrise.
The rest of the second week drops off again. Sunday the 9th through Tuesday the 11th are small and messy. Another small pulse shows up on Tuesday the 11th afternoon with a glassy 5 ft SSE swell. That’s a nice little bonus.
Things get a bit hairy on the 12th and 13th. Wednesday the 12th has a 7 ft south swell, but it’s cross-onshore and choppy. Thursday the 13th sees a big 10 ft south swell with a very high energy (3035). That’s only for experienced surfers, and the wind is cross-offshore, so it will be clean but big and powerful. The 8 ft on Thursday afternoon is still large.
So, to wrap it up: the best bets are Saturday morning August 1st for the glassy perfection, and Saturday morning August 8th for the long-period groundswell with glassy conditions. Tuesday afternoon the 11th is a nice little glassy bonus. Get on it.
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.
