The Lowdown
G’day, Rusty here. We’ve got a solid 16-day window with a lot of swell, but finding clean conditions will take some patience. The standout window is clear, though—Tuesday morning the 18th of August should be something special, and late in the run, we’ve got another beauty shaping up for Saturday the 29th of August. There are gaps with no surf recommendations here and there, mainly when winds are howling onshore.
Right from the off, Sunday the 16th of August kicks off with a clean but marginal call at Cable Station Reef. Swell is 6 ft from the WSW with a very long 16-second period (groundswell), but a fresh 19 mph NNE cross-offshore wind keeps things bumpy. The combined wave energy is moderate at 1531, so there’s push, but it’s not the best for the effort.
Monday the 17th of August goes downhill fast. A strong 22 mph NW cross-on wind with a lumpy 6 ft WSW swell (period 16 seconds, energy 1858) makes for poor conditions. By afternoon, it’s an 12 ft beast with a 28 mph onshore wind—only for the keenest, and even then, it’s ugly.
Now, Tuesday morning the 18th of August is the first true standout. Glassy conditions, zero wind, and a solid 12 ft WSW groundswell with a 16-second period (energy very strong at 5055). This is proper long-period, powerful swell. At a reef break, it should line up nicely, but at this size, it’s for experienced surfers only. The water temp is about average for the time of year over here. The wind is calm, so it’ll be smooth and clean. This is the best we’ll see for a while.
Wednesday the 19th and Thursday the 20th of August see the swell drop a little (8 ft–10 ft) but cross-on winds return, making it lumpy and marginal. Not worth paddling out.
Friday the 21st of August turns it around. Morning has a gentle 9 mph ENE offshore wind with a 8 ft WSW swell at a 15-second period (energy high at 2324). The afternoon goes glassy with an 8 ft swell and an ESE breeze so light it’s almost nothing—glassy conditions, excellent for experienced surfers. This is a strong runner-up for the best session.
The weekend of the 22nd and 23rd of August offers smaller swell (5 ft–6 ft) but clean conditions, especially Sunday with a light cross-offshore breeze and a 16-second period. More of a fun, manageable size for intermediates.
Then we hit a rough patch from Monday the 24th through to Thursday the 27th of August. Winds pick up, onshore, with lumpy surf and poor quality. Not much to get excited about.
Saturday the 29th of August is our other standout. Morning delivers glassy, calm conditions with a 7 ft WSW groundswell and a very long 18-second period (energy very strong at 3557). That long period means steep, powerful walls—excellent for experienced surfers. The afternoon gets choppy with a cross-shore wind, so make the most of the early session.
Sunday the 30th of August morning keeps the quality high: 10 ft WSW swell, 16-second period, light cross-offshore breeze, clean. Another expert-level day. By afternoon it bumps up to 13 ft, which is too big for this break.
Monday the 31st of August wraps things up with a glassy 10 ft morning, light wind, and excellent conditions for those who know what they’re doing.
In short: don’t miss Tuesday the 18th or Saturday the 29th of August. Mark your calendar.

Information about the Cable Station Reef Surf forecast
The above surf forecast table for Cable Station Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cable Station Reef can be found by selecting the local surf guide option on the grey menu. Our Cable Station 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 (Cable Station 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 Cable Station 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.
Cable Station Reef is 6 km (4 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.
