The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.
Right off the bat, I gotta be straight with you – the first few days are a write-off. We’re looking at a real messy start with strong winds and lumpy, choppy conditions. Nothing to get excited about until we get past that initial hump.
The first real chance of a wave comes on Sunday, August 2nd. The boys at Isolators are looking at a solid 8ft swell from the WSW, but the real story is the wind. On Sunday morning it’s a clean offshore from the NE at 12 mph, and by the afternoon it drops right off to a glassy 3 mph. That’s the kind of clean-up you want to see. The water temp is sitting at 66°, which is a touch warmer than normal for this time of year, so you might not need the thickest wetsuit. The wave energy is pumping hard, with a combined energy of 1427, so there’s plenty of push. The period is a long 14 seconds, so you’ll get those long, waiting sets – perfect for a reef setup like this. However, this swell is on the edge, just over 8ft, so it’s edging into expert territory. It’s a standout for the clean conditions, but only for the experienced crew.
Monday, August 3rd is another good shout. The swell drops a touch to 5ft, and we get a glassy flat calm in the morning with absolutely no wind. The energy is a moderate 936, and the period is a very long 15 seconds. That kind of period off a reef like Isolators can be a dream, but it can also make the waves a bit too straight for a beach break. This is a reef, so it should handle it well. The swell is more manageable, making it a good option for intermediate surfers looking for a clean, fun session.
After that, things go sideways again. From Tuesday, August 4th, the swell jumps up and stays big, mostly over 8ft and often hitting 10ft to 18ft. The wind is constantly cross-on or onshore, making it blown out and messy. The combined energy readings are massive, hitting four and even five-digit numbers like 5140 and 6460, which tells you there’s a ton of power, but it’s all going to waste with the wind. The setup looks more like a kite surfing day than a paddle session, with strong breezes and near gale-force winds forecast for the 8th of August. This is a long stretch of poor quality, lasting from the 4th right through to the 15th.
So, to put it simply: hold out for Sunday, August 2nd and Monday, August 3rd. Those are your two standout windows. After that, it’s a waiting game for the next weather system to sort itself out. The swell is there, but the wind is the enemy.
Rusty.

Information about the Isolators Surf forecast
The above surf forecast table for Isolators provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Isolators can be found by selecting the local surf guide option on the grey menu. Our Isolators 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 (Isolators) 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 Isolators 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.
Isolators is 65 km (40 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.
