The Lowdown
Alright, listen up. We got a pulse in the water right now, but this forecast is all about picking your spots. The first couple of days are gonna be a washout with the wind, but don't bail yet, there’s some proper glassy windows hiding in there.
It's a solid W/SW groundswell moving in. Tuesday the 18th has some size, pushing 12ft, but that W wind is gonna have it all chopped up. It's messy and not worth paddling out. The energy is strong, with readings around 6388, but it's just not clean.
Wednesday the 19th is still lumpy, with a cross-onshore breeze and showers. The swell drops a touch to 10ft, but it's still not doing it for me. We gotta be patient.
Now, Thursday the 20th is where it starts to get real. The wind drops out in the morning—dead glassy. The swell holds at 8ft from the WSW with a long 16-second period. The energy is still pumping, reading 3594. This is proper point break territory. Clean, lined-up waves with plenty of push. Water temp is about 64°, which is normal for this time of year. For the more experienced crew, this is the standout of the early week.
Friday the 21st keeps the good vibes with clean conditions in the morning, a light offshore breeze, and 7ft of WSW swell. It's a touch smaller, but still has shape. Energy is moderate at 2087.
Saturday the 22nd gives us another glassy dawn, with the swell easing to 7ft but still holding that long 16-second period. It's clean, it's overhead, and the point should be linking up perfectly. This is another cracking morning.
The window starts to close Sunday and Monday as the swell backs off and winds shift. It's not terrible, but it's dropping into the 5-6ft range and the wind becomes more of a factor. Energy drops into the low 1000s. Fun waves, but nothing special.
Then we hit a proper dry spell from Tuesday the 25th through to Friday the 28th. The wind goes howling onshore, the swell gets short and messy, and the quality just tanks. We got readings down around 684 and periods dropping to 8 seconds. It’s blown out, lumpy, and just plain ugly. For about four days, you won't want anything to do with it. The strong cross-onshore winds and chop make it more of a kiteboarding session than a surfing one.
But hang tight, because the second week looks promising. We come out of the weekend and things start to clean up. Saturday the 29th has a morning window with clean conditions and a 6ft WSW groundswell, pulling back to a 16-second period. It's a nice rebound.
Sunday the 30th is a beauty. Glassy conditions with the swell holding at 6ft from the W, and a long 15-second period. Energy is at 1371, so it's not huge, but it's clean and lined up. This is the pick of the second week.
Monday the 31st sees a bit more size, 8ft, with glassy conditions again in the morning. Energy jumps up to 2861. This is looking like a proper return to form, but remember, it's further out, so I'd call it promising but less certain.
After that, into September, there’s still swell in the 8-10ft range, but the winds get a bit funky and the periods shorten. It's not a total loss, but the magic of those glassy mornings is gone.
So, if you're keen, the clear standouts are the mornings of the 20th and the 22nd. They combine solid, long-period swell with perfect, clean conditions. The 31st is also worth marking on the calendar as one to watch. Crowds are likely at Avalon Point (Big Island) when it's good, but that's the price you pay for a wave like this.

Information about the Avalon Point Surf forecast
The above surf forecast table for Avalon Point provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Avalon Point can be found by selecting the local surf guide option on the grey menu. Our Avalon Point 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 (Avalon Point) 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 Avalon Point 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.
Avalon Point is 11 km (7 miles) from Mandurah. If you plan a holiday in Perth City Coast, look for hotels and other accommodation in Mandurah. Mandurah has rooms for a wide range of budgets as well as car hire and transport links.
