The Lowdown
Alright, Rusty here. Let’s talk about what’s on the table for the next stretch. We’ve got one spot on the radar, and it’s a bit of a specialist’s wave.
First up, we’re looking at Pea Break – a reef setup that’s built for the advanced crew. The water temp is sitting right around average for this time of year, so nothing unusual there.
The real story is the size. We’re kicking off Wednesday, August 19th, with a heavy 15 ft swell from the WSW, with a period of 15 seconds. That’s proper groundswell. The energy is massive (8590), so this is serious power. The problem is the wind. It’s a cross-shore SW breeze at 12 mph, which is putting a chop on the face. The conditions are described as marginal, so it’s not going to be clean, but for an experienced surfer who knows the reef, there’s plenty of water moving. Thursday afternoon, August 20th, the wind eases and turns cross-offshore, and the swell drops to 12 ft. That’s the moment it gets clean. The wave state is clean, and the energy is still strong (6494). Friday, August 21st, is the standout. Clear skies, a light ENE breeze at 3 mph in the morning, and a solid 12 ft SW groundswell (period 15 seconds) with clean conditions. The energy is still high (5329). This is the best on offer. The wind is basically glassy, and the reef will be handling that long-period swell well. This is a spot for experts only – 12 ft is big, and over 8 ft means it’s for the confident crew.
From Saturday, August 22nd, the size drops to 10 ft, but the wind picks up. The energy is still moderate (3953), but it’s not as clean. By Sunday, August 23rd, the period drops to 13 seconds, and the wind is stronger. The quality drops off. There’s a big gap in the quality after that. Monday, August 24th, and Tuesday, August 25th, are poor – onshore winds and messy conditions. Not worth paddling out.
Then Wednesday, August 26th brings another pulse of 15 ft swell from the WSW, with a 16-second period. The energy is very strong (11091). But again, it’s cross-shore wind and described as marginal. It’s raw power but not polished. The next clean window is Thursday, August 27th afternoon, when the swell drops to 8 ft, with a light cross-offshore breeze and excellent conditions for experienced surfers. The energy is moderate (2494).
After that, the swell fades. From Friday, August 28th, through to the end of the month, the wave heights stay below 8 ft, and the wind is mixed. The energy drops to 1000-3000 range, which is weak to moderate. There’s a glimmer on Sunday, August 30th morning, with a 8 ft WSW swell, very long period of 15 seconds, and a light cross-offshore breeze. The conditions are clean (2983 energy). That’s a decent session for the experienced surfer, but it’s not the standout of the first week.
Looking into the first week of September, Tuesday, September 1st is small, with 7 ft. Wednesday, September 2nd sees a return of 12 ft groundswell with a 16-second period and light wind, but it’s cross-shore and the energy is strong (5995). The wind is a light WSW in the morning, which could be okay. The afternoon gets a cross-offshore breeze, but it’s fresher. It’s a solid option, but again, for experts.
Thursday, September 3rd is a write-off. Strong onshore wind and rain make it messy.
So, the standout of the entire forecast is Friday, August 21st. The combination of a reliable 12 ft SW groundswell (15 seconds), clear skies, and a near-glassy ENE breeze in the morning will make Pea Break as clean as it gets for that size. It’s a big wave, so if you’re not comfortable on a reef with 12 ft moving, it’s not the day. For the experts, that’s the one.
Rusty.

Information about the Pea Break Surf forecast
The above surf forecast table for Pea Break provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Pea Break can be found by selecting the local surf guide option on the grey menu. Our Pea Break 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 (Pea Break) 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 Pea Break 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.
Pea Break is 72 km (45 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.
