The Lowdown

Alright folks, it's Rusty here, and I've been staring at the charts for Cobblestones. Let's be straight with you—this forecast is a wild ride, starting with a lot of noise before we get to a couple of real golden windows. Don't get your hopes up for the first week, but there's a light at the end of the tunnel.

Right now, into Saturday the 1st of August, we've got a massive 13ft to 16ft SW groundswell hitting. The water is a touch warmer than normal at 67°, but that's where the good news ends. The wind is all over the shop—cross-on and cross—making it choppy and messy. The combined energy is massive (6847 to 10621), but it's a washout. Poor surf, marginal tides, none of it's worth a paddle.

Sunday the 2nd sees the swell drop to a cleaner 10ft to 12ft from the SW, and we get some sweet NE to NNE cross-offshore breezes. It cleans right up, especially in the afternoon with light winds. The wave energy is still solid (3936 to 4148), but the period is a long 13 seconds. This is a proper groundswell, so at a reef break like Cobblestones, it should line up nicely. It's a solid option for the advanced crew, but nothing that's going to blow your mind just yet.

Monday the 3rd is a step down. The swell fades to 6ft to 6ft, and while the morning is clean, the wind swings NNW and gets fresh. The energy drops right off (1558 to 1671), and the afternoon gets lumpy. It's a pass.

For the rest of the first week, from Tuesday the 4th through to Friday the 7th, it's a write-off. We're looking at a relentless run of onshore and cross-onshore winds from the W, WNW, and NW. Swell stays big, 13ft to 16ft, but it's all wind-slapped. The energy is still high (9137 to 12631), but the quality is zero. Cobblestones is getting hammered. This is a stretch for the kite surfers, not for us paddle surfers.

Then we hit the weekend. Saturday the 8th of August is a full-on caution. The swell pumps up to a massive 21ft to 30ft from the WSW. The combined energy is off the charts (15692 to 29461). The notes say the swell is too big for this break. Even if the wind were glassy, those are expert-only, life-or-death waves. And the wind is a near gale. Stay on the beach.

Sunday the 9th is similar. Swell is still huge at 26ft to 23ft, energy is through the roof (38195 to 48385), and the wind is onshore or cross-on. Too big, too messy. Another day for the big-wave chargers only, and even then, it's sloppy.

Alright, here's where it gets interesting. After a sloppy Monday the 10th, we see a shift. Tuesday the 11th of August is your first real standout. The swell eases to a much more manageable 13ft from the SW, with a 16-second period. The wind is light from the SSE, creating a gentle cross-shore with just a slight chop. The energy is strong (8462 to 8594). This is a proper, lined-up groundswell at a reef. It's not perfect, but it's the best thing we've seen in a week. The scores are high, and it looks like quality surf for the experienced.

Wednesday the 12th of August is also clean. The swell drops to 10ft from the SW, but the wind goes light N to NE, cross-offshore. The conditions are clean and the notes are calling it "excellent" for experienced surfers. This is a good, solid session.

But the real gem of the whole forecast, the one you should mark on your calendar, is Thursday the 13th of August. The swell holds at a punchy 12ft from the SW, with a 17-second period. The wind is offshore from the NE, moderate breeze, creating clean, lined-up waves. The energy is high (9260), and the notes say "exceptional surf conditions for expert surfers." This is the one. Cameras out, call in sick. This is top-tier Cobblestones.

Friday the 14th is still fun with cleaner conditions and 10ft to 12ft swell, but the wind is a bit more cross-offshore. A good backup.

After that, the weekend of the 15th and 16th looks messy again. The wind swings onshore and the swell gets jumbled. There's a big 18ft swell on Sunday the 16th, but it's blown out or too big. The window closes.

So, to wrap it up: the first 10 days are mostly a bust. The standout is unequivocally Thursday the 13th of August. The secondary pick is Tuesday the 11th and Wednesday the 12th. Don't sleep on that Thursday.

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.
