The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up on the 16-day stretch for the Artificial Reef.
Right off the bat, I gotta be straight with you – this is a tough one. We’re looking at a long, dry spell with next to nothing on offer for the first week and a half. The forecast shows zero swell energy for the first nine days straight. It’s a blank run, plain and simple. The water is sitting at 63°, which is a bit colder than normal for this time of year, so it’s not just you feeling the chill.
The first real hint of life shows up on Saturday the 22nd of August, but it’s weak. We’re talking a tiny 2 ft swell from the SSW with a short period of 3 seconds, and the combined energy is a measly 8 (weak). The wind is a cross-shore, so it’s not clean either. It’s not worth paddling out for.
Sunday the 23rd of August morning is the first time we get a bit of height. The swell builds to 4 ft from the SW, period bumps up to 5 seconds, and the combined energy hits 84 (weak). Still, the wind is cross-shore, and the forecast still calls it “poor surf conditions.” It’s a bigger, choppy mess.
Then we go quiet again. More days of nothing, with some strong onshore winds and rain showers rolling through the 25th and 26th. That’s kite-surfing weather, not for a paddle board.
The only real standout in the whole window is on Monday the 31st of August. We get a long-period groundswell sneaking in. The morning has a tiny 1 ft swell from the west, but with a very long period of 18 seconds, and the combined energy is 55 (weak). The wind is a light cross-offshore, so it’ll be clean. This is a very classic “reef” scenario – that long period will wrap in nicely, but the size is tiny. It’s more of a longboard glide than a proper wave. The afternoon stays small at 1 ft, but the wind turns cross-onshore, chopping it up.
So, the honest truth? There’s no good surf in this 16-day window. The Artificial Reef is sheltered and needs a specific direction, and we just aren’t getting it. The only morning that *might* wet your toes is the 31st of August, and that’s a prayer. For an area this consistent, this is a rare dead run, but the forecasts can always change.
Rusty.

Information about the Artificial reef Surf forecast
The above surf forecast table for Artificial reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Artificial reef can be found by selecting the local surf guide option on the grey menu. Our Artificial reef 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 (Artificial reef) 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 Artificial reef 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.
Artificial reef is 5 km (3 miles) from the very large city of Fremantle. If you plan a holiday in Perth City Coast, look for hotels and other accommodation in Fremantle. Fremantle has rooms for a wide range of budgets as well as cheap car hire and transport links.
