The Lowdown
Alright mate, Rusty here. Let’s break down what’s coming for Nanarup Beach.
The water is sitting at 64°F, which is a touch warmer than usual for this time of year – not bad for a longer session in the lineup.
The first standout is Friday morning, 21 August. A glassy, clear morning with a 7ft SSW swell rolling in at a 15-second period. The wind is a light NW offshore at 3 mph, making for clean conditions. The combined energy is pumping at 2048, so there’s plenty of push. This one’s for the more experienced crew – it’s a solid size and that long period will hold up nicely on the beach. It’s a consistent break, so you’ll get waves, but you might have company as crowds are sometimes here.
Saturday morning, 22 August, is also a beauty. Clean offshore NW wind at 3 mph with a 6ft SSW swell and a very long 16-second period. Combined energy is still strong at 1925. Again, the size is on the edge for beginners, but for anyone with a bit of time in the water, it’s going to be a fun session.
There’s a lull after Sunday, with some poor conditions and smaller waves through the middle of the week. But don’t write it off – the forecast picks up again.
Wednesday morning, 26 August, is a cracker. Clean, clear conditions with a 6ft SSW swell and a massive 20-second period. The combined energy hits 3787, which is serious power. The wind is a light WNW cross-off at 9 mph. This is another one for the experienced surfers – the long period will make for some great lines, but it might close out a bit on the beach.
Then, looking ahead to Sunday morning, 30 August, we’ve got another solid pulse. A 7ft SSW swell with a 19-second period, light offshore NNW wind at 16 mph, and combined energy of 2994. Clean, powerful, and calling for someone who knows what they’re doing.
The last week of the forecast has some bigger but messier days. Friday morning, 5 September, shows an 12ft SSW swell, but it’s cross-on and choppy, so that’s more of a kite-surfing day than a clean paddle session. The swell is huge, but the quality isn’t there.
Overall, the mornings are your best bet. The first two weekends and the Wednesday 26 August are the real highlights. The long-range stuff around 5 September is promising but less certain, so keep an eye on it.
Rusty.

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