The Lowdown
Alright folks, Rusty here. Let’s have a look at what the next couple of weeks are shaping up like. We’re looking at a run that’s got some real juice in it, but you’ve gotta pick your moments. This isn’t a straight shot of perfect sessions; it’s more about dodging the wind and the size.
The first real action kicks off Wednesday afternoon the 19th. But right off the bat, we’ve got a problem. That swell is pumping – a solid 10 ft from the WSW, with a massive 4208 wave energy reading. That’s a lot of ocean moving. For a beginner break, this is way too much juice. It’s big, it’s powerful, and it’s really only for the experienced crew who know what they’re doing. If you’re a learner, stay on the sand for that one.
The real standout window is actually coming up quick. Thursday morning the 20th at Singleton. The wind is going glassy – dead calm – and that’s gold. You’re looking at a 8 ft swell from the WSW with a very long 16-second period. That’s proper groundswell energy right there, tons of push. For experienced surfers, this is as good as it gets. The water temp is about average for this time of year, so a spring suit is the call. Be aware, the long period will make the waves stand up and section off, so it’s not a straight crumbler. That glassy morning is the session to circle on the calendar.
Friday morning the 21st offers another good clean look. The swell drops a touch to 8 ft from the WSW, but the wind shifts offshore from the ENE. That’s a clean, lined-up wave. The period is still a solid 15 seconds. It’s another one for the experienced surfer, no doubt.
After that, the wind gets messy for a bit. Saturday morning the 22nd goes glassy again with a 6 ft swell, which is more manageable, but the real magic is gone by the afternoon when the southerly wind kicks up chop.
Monday morning the 24th looks tidy. A 6 ft WSW swell with a cross-offshore breeze from the NNE. It’s clean, with 1423 energy reading. Not a standout, but a solid session.
Now, keep an eye on Wednesday the 26th. We get another pulse of big energy: 10 ft from the WSW with a massive 5378 reading and a 17-second period. That is a heavy, heavy groundswell. The morning wind is light cross-shore, which would be fine if it weren’t so damn big. Again, this is expert-only territory, and honestly, the size is likely going to make it a washing machine for most.
The following week has some promise, but it’s less certain. Thursday morning the 27th brings a 7 ft swell with an offshore breeze from the ENE. That’s a clean, powerful wave for the experienced surfer. Monday morning the 31st also looks promising with a 6 ft swell and a cross-offshore wind. The conditions set up nicely, but forecasts that far out are always a bit of a gamble.
There is a gap right at the start with no surf on offer, but once it starts, it keeps rolling. The first few days have the best quality before the wind turns. The big swells are the story here, so bring your big-wave board and your patience.
Rusty.

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.
