The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer.

The next few days are a mixed bag – plenty of size, but the wind is going to be a player. The big news is a solid run of SW groundswell, with some very long period energy (16-17 seconds) which will make for some serious, powerful lines at this exposed reef break. Water temp is sitting at a balmy 68°, which is a full 4° warmer than normal for this time of year – you’ll be fine in a spring suit.

The action kicks off Monday, August 3rd, but it’s not the one. We’ve got head-high swell at 6ft, but the wind is howling out of the north at 16 mph. It’s not proper offshore and the energy is already high (1455), but the outlook is marginal. Don’t get too excited.

Tuesday the 4th sees the swell jump to 12ft from the WSW. That’s serious size, but the wind swings onshore out of the west and it’s choppy. The combined energy is pumping (8079), but this is strictly for the experienced crew only. Beginners, sit this one out.

Now, Wednesday the 5th. That’s the one to circle. We’re looking at a solid 16ft SW swell with a 16-second period. The morning is a bit wet, but the afternoon… glassy. Dead flat. Light breeze from the NW at 3 mph. The combined energy is massive (11141). This is a true standout – big, clean, and powerful. This is for experts only, but if you’ve got the skills, it will be unforgettable.

Thursday the 6th drops a touch to 13ft, but the wind is cross and cross-on. Still plenty of juice (8157), but it won’t be as clean as Wednesday. Friday the 7th is a write-off with a strong onshore flow and lumpy conditions. Saturday the 8th sees the swell peak at a massive 20ft from the SW with 17133 energy – it’s genuinely too big for this break. No go for paddle surfing, but a kite surfer would be in heaven.

We get a bit of a breather Sunday the 9th with 15ft swell, but it’s onshore and messy. Monday the 10th is heavy again (18ft, 17000 energy) and the wind is howling. Another one for the kiters.

The second week looks promising but less certain. Tuesday the 11th is absolutely massive – 28ft swell! That’s a staggering 40706 energy. The ocean is angry. Only the absolute top-tier charger should even consider it.

Wednesday the 12th is another big standout. The swell eases to a still-hefty 18ft, but the wind goes cross-offshore from the north at just 3 mph. Clean conditions for the experts. Thursday the 13th is smaller at 12ft with glassy conditions in the morning – a nice drop in intensity.

Friday the 14th through to Monday the 17th offers consistent 12ft to 15ft SW/WSW swell, and the wind looks much better. Friday afternoon is clean with a cross-offshore breeze. Saturday the 15th has proper offshore winds all day. Sunday the 16th afternoon is a beauty – 13ft swell, clean, light winds. And Monday the 17th afternoon is another screamer with clean 15ft surf.

Tuesday the 18th finishes the run with 15ft swell, but the wind goes cross and then onshore, so the quality drops.

Summing it up: The absolute top pick is Wednesday afternoon, August 5th – that’s the day for the hardcore crew. If you want a slightly more manageable session with clean conditions, lock in Saturday the 15th or Sunday the 16th. Stay safe out there.

Rusty.

Information about the Cobblestones Surf forecast

The above surf forecast table for Cobblestones provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cobblestones can be found by selecting the local surf guide option on the grey menu. Our Cobblestones 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 (Cobblestones) 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 Cobblestones 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.

Cobblestones is 85 km (53 miles) from the city of Bunbury. If you plan a holiday in Margaret River, look for hotels and other accommodation in Bunbury. Bunbury has rooms for a wide range of budgets as well as car hire and transport links.
