The Lowdown
Alright, Rusty here. Let’s take a good hard look at what the surf’s doing across this whole 16-day window. It’s a pretty bleak run for Salt Rock, to be honest. The first few days are a write-off, and there are long blank stretches in between. We’re looking at a gap of several days with no real recommendations, then a bit of a flicker, then another quiet spell before the second week tries to throw us a bone.
Right now on Wednesday, September 16th, it’s a mess. A 6ft east swell is coming in but the wind is a cross-on from the east at 9 mph, making it choppy and unappealing. The water’s sitting at 69°, which is a bit colder than normal for the time of year (anomaly of -2°). The whole sweep of the morning is a dud, and the afternoon gets even worse with a strong 25 mph cross-shore. Thursday offers a slight glimmer in the afternoon – we get a 8ft south swell with a short 8 second period, and the wind switches to a clean cross-off from the southwest at 16 mph. That’s the cleanest and biggest we’ll see for a while, but the energy is high with moderate combined swell energy (959), and it comes with a score that’s still marginal. Not a standout, just the best of a bad lot.
After that, everything tanks. Friday brings a massive 10ft swell but with howling onshore winds, and it’s chaotic. Saturday afternoon actually goes glassy, and there’s a 7ft east-southeast swell with 9-second period and a combined energy of 828. Conditions look clean enough, but it’s still a cross-on setup and the overall quality is just “expect very good surf conditions” on the scorecard – still not strong enough to call a win.
From Sunday the 20th right through to the end of the month, it’s practically all poor surf conditions. The wind is mostly cross or cross-on, the swell drops off to under 3ft, and the scores are zeros across the board. There’s a long stretch of nothing here.
Then on September 25th, a long-period 16-second groundswell from the south-southwest rolls in, pushing 5ft. The combined energy is strong (1027 to 1044), but the wind is a cross-on from the south at 9 mph. The period is long, which means it’s best suited for point breaks and reefs, not so much a beach break like Salt Rock. The afternoon is marginal at best. That’s the only real standout in the second week, but it’s a long way off and the wind isn’t doing us any favours.
So for the entire forecast period, your only real window is Thursday afternoon, September 17th, where that 8ft south swell sits with clean offshore-ish wind, and maybe keep a watch on Saturday afternoon, September 19th, for glassy but smaller surf. The rest? Honestly, it looks more interesting for kite surfing than paddle surfing given the combo of big swell and strong, ugly wind.
Rusty.

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