The Lowdown
Right. Rusty here. Let’s cut through it.
Look, Cowries is the only spot on the table, and it’s a reef-and-point setup that’s fairly exposed. Thing is, it’s a beginner-friendly wave, but “fairly consistent” doesn’t mean much when the whole 16-day window is a flat spell with a few tiny blips. Water temp is sitting at 64° – bang on normal for this time of year. No drama there, but you’ll be waiting a long while for anything worth paddling out for.
From now through the rest of August and into the first week of September, it’s a grim stretch. Days and days of piddly waist-high slop and junk wind. A couple of mornings – like Friday the 14th morning – go glassy with 3ft from the south, but the period is short (8 secs) and the energy is weak, only 194 (moderate energy level, but barely). Still, glassy conditions at a point break mean you could get a few clean little peelers if you’re desperate. Not a standout by any stretch. Then Saturday the 15th morning shows a pulse of 5ft from the south, period 8 secs, cross-off wind from the south, and energy climbs to 354 – that’s moderate energy, and the winds keep it clean. That’s the only half-decent window in the first week. Still, it’s ordinary; score is low, not a standout.
Then the second week – more of the same. Small, short-period junk. A few mornings like Friday the 21st offer light offshore from the west with 3ft from the east-northeast, period 8 secs, energy 113 (weak). Clean but tiny. Even the morning of Saturday the 22nd goes glassy with 3ft from the east-northeast, but period 10 secs, energy 156 (moderate). Conditions are glassy, but the swell is barely there. Not worth a trip.
The only true standout is buried way out in the forecast. On Thursday the 27th of August, late in the window, Cowries gets a solid pulse – 8ft on the Thursday morning from the south, period 9 secs, light offshore from the southwest. Energy rockets to 1177 – that’s very strong wave energy. This is big for a beginner spot, over 8ft – experts only. The afternoon jumps to 10ft from the south, but winds turn cross-onshore, which will chop it up. Still, that Thursday morning is the best on offer, but it’s a long-range promise, and you know how that goes – keep an eye on it, but don’t book the week off.
Overall, this is a bleak outlook. If you’re jonesing, the glassy Friday 14th morning or the clean Saturday 15th morning might give you a couple of rides, but don’t expect much. For the rest, it’s a long wait to that big swell at the very end. Honestly, if the wind stays strong and the swell is messy, this setup could be more interesting for the kite crew than paddle surfers.
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.
