The Lowdown

G'day, Rusty here. Let's talk about the surf ahead at Cobblestones. We've got a big 16-day window, and it's a bit of a mixed bag. The water is sitting at 66°, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit.

Swell kicks off this Thursday, the 30th of July. It's not the most promising start, with a 6ft SW swell at 14 seconds, but the wind is a cross-off from the NNE at 12 mph, keeping things clean. The combined energy is moderate (1931). It's a bit marginal, but there's a wave to be had if you're keen. The afternoon sees the wind swing cross-shore, so it'll get a little bumpy.

Friday, the 31st, is a write-off. The swell jumps to 12ft and then 13ft, but the wind is onshore and howling from the NW at 22 mph, turning it into a lumpy mess. The energy is strong (6659), but you won't want to be out there.

Saturday the 1st of August is a similar story. Solid 13ft to 16ft SW swell, but the wind is cross-onshore or onshore, making it choppy and ugly. The energy is very strong (11723) on Saturday afternoon, but it's not for paddling.

Sunday the 2nd of August is where it gets interesting. The morning has a 12ft SW swell with a clean cross-off breeze from the NE at 9 mph. The energy is strong (3677). The afternoon is the real standout for the first week. The swell drops to 8ft SW, the wind goes light and variable from the north at 3 mph, and the conditions are clean. The combined energy is moderate (3118), but the glassy conditions will make for some fun, lined-up waves. Great for experienced surfers.

Monday the 3rd of August sees the swell back to 7ft to 8ft, but the wind turns cross-onshore, so it's not as good as Sunday.

The second week is a tale of two things: massive swell and terrible wind. From Tuesday the 4th of August through to Sunday the 9th, the swell is consistently over 13ft, often hitting 16ft or 20ft, with very strong energy (up to 16439!). But the wind is almost always onshore or cross-onshore, and often strong, which makes it completely blown out. Sunday the 9th is a special mention: the wind and tide are actually favorable for a moment, but the swell is predicted to be too big for this break, so it's really only for the absolute elite.

Monday the 10th of August brings a bit of relief. A 13ft SW swell with a cross-shore wind from the NNW at 12 mph, offering moderate cross-shore conditions. The energy is strong (8522). It's a step up from the days before, but still not perfect.

The rest of the window from Tuesday the 11th to Friday the 14th of August is a mix of strong winds, onshore flow, and messy conditions. The swell stays big, but the wind just won't cooperate.

Honestly, the best on offer in this whole 16-day stretch is Sunday afternoon, the 2nd of August. That 8ft SW swell with the light, clean wind is the only time you'll get truly smooth, clean waves. If you can get out then, do it. Otherwise, the rest of the period is mostly for the hardcore, or the kite surfers, because the wind and swell combo is more suited to them than a paddle surfer.

Rusty, signing off.

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.
