The Lowdown
Alright, Rusty here, and I’ve got a good look at what’s on the menu for Singleton over the next couple of weeks. We’ve got a big run of surf coming, but it’s not all for the faint of heart. Let’s get into it.
First up, the water temp is sitting at 63.5°, which is a touch under 2° cooler than the norm for this time of year—nothing wild, just a bit on the crisp side. You’ll want a decent spring suit.
The first real action kicks off on Tuesday morning, August 18th. We’ve got a solid 11.5 ft swell rolling in from the west with a very long 16-second period. That’s a heavy groundswell, and it’s packing some serious grunt—the combined energy reading is 6388, so we’re talking strong, powerful water. The wind is a cross-on from the west at 9 mph, so it’ll be a bit chop topside. This one is pushing the limits for most, way too big for beginners and honestly, it’s a beast for the experienced crew too. It’s exposed and it’s gonna be a handful.
Wednesday morning, August 19th, still sees a chunky 8.2 ft to 9.8 ft west swell, but the wind is still cross-on from the WNW, keeping things fairly choppy. The energy is still high, but the conditions are a bit messy. Not a standout.
Now, here’s where it gets interesting. Thursday morning, August 20th, the wind goes completely glassy. Flat calm. The swell has dropped to a still-juicy 8.2 ft from the WSW with a 16-second period. The combined energy is 3594. This is the kind of morning where Singleton could really show its teeth. The waves are going to be clean, powerful, and lined up. For experienced surfers only, this is the pick of the first week. The glassy conditions are a massive plus.
Friday morning, August 21st, is another glassy start with a 7.2 ft WSW swell and a 15-second period. The energy is still moderate to strong at 2087. The wind is a light offshore from the ENE at 3 mph. This is clean, beautiful, and a step down in size, making it a bit more manageable for the strong intermediate crowd. Another excellent morning session.
Saturday morning, August 22nd, brings a 6.6 ft WSW swell at a very long 17 seconds. The wind is a clean cross-off from the NNE at 6 mph. The energy is 2171. This is a solid, well-shaped wave with clean conditions. It’s not the biggest, but the quality is there.
We hit a bit of a lull from Sunday, August 23rd, through to Monday, August 24th, with dropping swell and onshore winds turning things sloppy. Tuesday, August 25th, is a write-off with strong onshore winds and a short, messy 8.2 ft to 11.5 ft swell. The period drops to just 7 seconds on Tuesday morning—that’s wind swell, not worth paddling for.
Then, the second week comes alive. Wednesday morning, August 26th, is glassy calm again with an 8.2 ft WSW swell at 15 seconds. The energy is a strong 2727. Clean, powerful, and a proper session for the experienced.
Thursday, August 27th, is a drop-off day with smaller swell and cross-on winds.
But hold onto your board. The end of the run is where the real magic might happen. Friday morning, August 28th, we’ve got a 3.6 ft swell from the west with a massive 20-second period. That’s nearly a minute between sets. The wind is a clean offshore from the east at 9 mph. The energy is 1425. This is a long-period groundswell. At a beach break like Singleton, that long period can make the waves reel a bit straight, but with offshore winds and clean conditions, it’s going to be a special, glassy day for the guys who know how to read the ocean.
Saturday morning, August 29th, is another cracker. A 6.6 ft west swell at 16 seconds with a moderate offshore wind from the ENE at 12 mph. The energy is 2194. Clean, offshore, and a nice size for the strong surfers.
But the real standout of the whole outlook? That’s Sunday morning, August 30th. We’ve got a 7.9 ft west swell, 18-second period, and a clean offshore breeze from the NE at 16 mph. The combined energy spikes to 4506. That’s a lot of power, but the wind is perfect. This is a world-class morning in the making for Singleton. Clean, offshore, and a solid groundswell pushing through. It’s still a couple weeks out, but if it holds, that’s the one to circle on the calendar.
Monday, September 31st, we see the swell get huge again—13.1 ft from the west—but it’s cross-shore, and the file says it’s too big for the break. Same for the start of September. A lot of power, but not user-friendly.
So, to wrap it up: the best windows are the glassy mornings of Thursday August 20

Information about the Singleton Surf forecast
The above surf forecast table for Singleton provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Singleton can be found by selecting the local surf guide option on the grey menu. Our Singleton 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 (Singleton) 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 Singleton 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.
Singleton is 5 km (3 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.
