The Lowdown

Right, cobber, let’s have a look at what’s coming up for Cobblestones. This is a solid, exposed reef setup that needs a good SSW swell, and it’s for advanced crew only. The water’s a touch warmer than normal for this time of year, sitting at 67°F, so that’s a nice bonus.

We’ve got a rough start, though. From Saturday the 18th right through to Monday the 21st, it’s a write-off. The wind is all over the shop, mostly cross-onshore or onshore, and the surf is lumpy, choppy, and messy. The combined swell energy is massive – over 12,000 (12392) on Saturday afternoon – but it’s just being trashed by a fresh 19 mph westerly. Not worth paddling out.

Things start to look up on Tuesday the 22nd. The morning session is the real standout of the first week. The wind goes glassy, dead calm from the ENE at only 3 mph, and the swell is a solid 10 ft from the SW with a nice 13-second period. The combined energy is pumping at 4306, and the conditions are described as excellent for experienced surfers. That’s the one to circle on the calendar. The afternoon stays clean-ish but gets a light cross-onshore, so the morning is the pick.

Wednesday the 23rd and Thursday the 24th offer clean conditions with cross-offshore winds, but the swell starts to drop. You’re looking at 8 ft to 7 ft from the SW, with combined energy dropping from 2125 to 1688. Still fun for the advanced crew, but not a standout.

Then we hit a big gap. From Friday the 24th afternoon through to Monday the 27th, it’s all poor surf conditions again. Strong winds, cross-onshore, onshore, rain, and the swell gets messy. The energy on the 26th and 27th is huge – over 8,000 (8338) – but with 25 mph winds, it’s just a washing machine. Not for surfing.

The next real highlight is Tuesday the 28th morning. Another glassy session, with the wind dropping to 3 mph from the SW, and the swell comes in at 8 ft from the SSW with a 13-second period. Combined energy is 2594, and it’s described as excellent for experienced surfers. That’s a clean, powerful morning.

After that, the swell fades right down to 3 ft on the 29th, but with a very long 18-second period from the SW. That’s a groundswell, and it’ll be clean with cross-offshore winds from the N. The energy is low (around 1000), but it might offer some lined-up waves for those who know the reef.

The second week gets interesting. On the 30th, the swell jumps back up to 8 ft from the WSW with an 18-second period, and the combined energy is 6504. The wind is a strong 25 mph cross-offshore from the N, so it’ll be clean but very windy. That’s a powerful, fast wave, but only for the experts.

The real big one, though, is at the very end of the forecast. On the 31st of July, we’ve got a 16 ft swell from the WSW with a 17-second period. The combined energy is a massive 12,892 (12892), and the wind is light and onshore, so it might be a bit soft. But the size is there.

Then, on the 1st of August, it’s predicted to be too big for the break – 18 ft from the SW. The energy is over 16,000 (16026), and the wind is light cross-offshore from the NE. That’s a monster, but the file says it’s too big for this spot. The 2nd of August still has a 15 ft swell from the SW with a 15-second period, and clean, cross-offshore winds from the NNE. That’s a proper, powerful day for the elite.

Overall, the best on offer is the glassy morning of Tuesday the 22nd of July if you want clean, powerful surf, and the big, clean swell on the 2nd of August for the experienced crew. The rest of the window is a mixed bag, with a lot of wind-affected days.

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.
