The Lowdown
G’day, I’m Rusty. Let’s break down what Smiths Beach is doing for the next couple of weeks.
We’re starting off a bit slow. Monday the 17th has a clean morning with a 4ft SW swell, a light cross-off breeze, and decent energy (501). The water is 56°, pretty normal for this time of year. But the afternoon turns choppy with onshore wind. Tuesday the 18th is the same story: clean morning with 4ft SW swell, then messy by afternoon. Wednesday the 19th has a strong offshore but only 2ft of swell and a 25 mph wind – hard work. Thursday and Friday are clean but small or just okay. Saturday the 22nd brings the first real size: 6ft SW in the morning, clean, with big energy (1719). That’s getting a bit much for beginners. Sunday the 23rd stays around 5-6ft but the wind picks up.
Then we hit a rough patch. Monday the 24th through Wednesday the 26th is blown out and tiny. Don’t bother.
Thursday the 27th is a proper standout – morning has a clean 3ft SW swell with a super long 18-second period, light cross-off (6 mph), and nice energy (647). By afternoon it goes glassy with a 3 mph WSW breeze and 3ft SW swell at 17 seconds. This is as clean as it gets – small but perfect lines.
Saturday the 29th is for the big dogs – a solid 10ft SW swell in the morning, long 14-second period, light cross-off, and massive energy (3273). Experts only. And Monday the 31st is the absolute standout – 10ft WSW swell with a 17-second period, light offshore from the NNE, and energy at a whopping 8292. Clean, powerful, and for experienced surfers only. That’s a session to remember.
After that, Tuesday the 1st of September drops to 5ft with a strong 25 mph offshore – clean but tough to paddle into.
So round it up: first week has some clean mornings, but the real gold is Thursday the 27th for small-wave perfection, and Saturday the 29th and Monday the 31st for big-wave adrenaline. Smiths Beach is a beach and point set-up, so those long-period swells will wrap in clean. Crowds can happen, so be early on the good days.
Rusty.

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