The Lowdown

Righto, Rusty here. Let’s have a look at what’s shaping up for Cobblestones.

We’ve got a solid run of surf on the cards, but it’s a tale of two halves. The first week is looking cleaner and more manageable, while the second week gets bigger and more unruly.

The best chance for a real standout session is Thursday the 30th of July. The water is a touch warmer than normal for this time of year, sitting at 67°.

Kicking off on Thursday the 23rd of July morning, we’re straight into it. The swell is a solid 8 ft from the SW with a 14-second period, packing serious energy (2893). The wind is a moderate offshore from the NE, so the lineup at Cobblestones (reef) will be clean. This is serious power for experienced surfers only. By the afternoon, the wind drops to a glassy 3 mph from the NW, and the swell holds at 8 ft SW. That’s a beautiful window of clean, lined-up reef waves.

Friday the 24th sees the swell drop to 6 ft SW, with a cross-offshore breeze. It’s cleaner, but the energy is down (950). Saturday the 25th is similar, with 6 ft SW and a cross-offshore wind. The quality is a bit more mixed, but still surfable.

Sunday the 26th is a strange day. The morning is a write-off with a strong cross-shore, but the afternoon brings a change. The swell jumps to 13 ft from the W, but with a short 9-second period. The wind is light and cross-offshore, so it’s clean. However, the combined energy is massive (3523) and the short period means it’ll be a bit lumpy and unpredictable. It’s for the brave, not the faint-hearted.

Monday the 27th is a no-go. The swell hits 16 ft SW (energy 15234) – that’s colossal for this break. The wind is cross-shore, and the forecast says it’s simply too big. Leave it for another day.

Tuesday the 28th is a redemption day. The swell drops to 10 ft SW with a 14-second period, and we get a gentle offshore breeze from the ENE. The water is clean, the energy is high (3768), and it’s a quality window for experienced surfers. The afternoon holds 8 ft SW with the same offshore breeze.

Wednesday the 29th is a little more mixed with a cross-offshore breeze, but the swell is still a solid 8 ft from the SW, with a very long 17-second period. That’s true groundswell.

Now, the standout. Thursday the 30th of July. The afternoon is the pick of the whole forecast. The swell is 12 ft from the SW, with a 17-second period. The combined energy is huge (7201). But the wind is a light 6 mph from the NNE, which is a clean cross-offshore. The forecast says it’s exceptional for expert surfers. This is the one to circle on the calendar. The morning before it is also good, with 7 ft SW and a 19-second period, but that afternoon is the gem.

Friday the 31st of July continues the run of big swell, with 16 ft SW in the morning (energy 11532) and 13 ft in the afternoon. The wind is cross-offshore, but this is strictly for the experts.

From Saturday the 1st of August onwards, the conditions start to deteriorate. The wind swings cross-shore and then onshore, and the swell remains big, from 12 ft to 16 ft. The energy is massive, but the wind is messy. Sunday the 2nd of August has rain showers and a cross-onshore wind with 15 ft SW swell. Not ideal.

The run of poor conditions really sets in from Monday the 3rd of August. The wind is a moderate cross-onshore, and the swell is still 8 ft. It’s choppy and messy. This continues through to Wednesday the 5th of August, with strong onshore winds and rain. It’s a write-off.

Thursday the 6th of August sees a slight improvement with a cross-shore wind, but the swell is 13 ft to 16 ft SW. The wind and tide are favorable, but the swell is predicted to be too big for this break again. Friday the 7th of August is the same story: massive 16 ft SW swell with a cross-onshore wind.

So, to sum it up: the first week has two clear winners. The glassy afternoon of Thursday the 23rd and the big, clean, long-period swell on the afternoon of Thursday the 30th of July. That last one is the real standout. The second week is mostly blown out or too big, so don’t get your hopes up after the 31st.

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.
