The Lowdown
G’day, Rusty here, checkin’ in for a proper look at what’s comin’ our way at Cave Rock over the next couple of weeks. We’ve got a bit of a slow start before things get real interesting.
The first few days, Saturday and Sunday (the 5th and 6th of September), are pretty average. Small, messy waves from the SSE and E, around 3ft to 7ft, but the cross and cross-onshore winds are wreckin’ any chance of a clean face. The wave energy is moderate at best, sittin’ around 440 to 966, and it’s just not worth paddlin’ out for the average Joe. You’ll be fightin’ chop for not much reward.
Then Monday the 7th of September – that’s the standout. Monday morning is a beauty. We’ve got a solid 10ft swell rollin’ in from the S with a long period of 17 seconds – that’s proper groundswell, heaps of energy and shape. The combined wave energy is a strong 4566, and with a light offshore breeze from the N, it’s gonna be clean as a whistle. Now, this is a reef break, so that long-period groundswell is gonna peel beautifully here, not close out straight like a beach break. This is advanced territory only though – 10ft is big, and it’s for experienced surfers who know the lineup. The water temp’s about average for this time of year, nothin’ unusual. Crowds can be a thing here sometimes, but with a Monday mornin’ and a clean, big swell, you might get a few out – but it’ll be worth it. Monday afternoon gets a bit sketchy with a fresh cross-shore, so grab that morning session.
After that, the week goes quiet again. Tuesday (8th) through to Friday (11th) is a write-off – tiny waves, poor winds, and weak energy down around 41 to 253. A few glassy moments on Friday arvo, but with only 0.7ft of swell, it’s barely a ripple.
Now, Saturday the 12th of September shows a bit of life again. A 8ft to 8ft swell from the SSW and S rolls in, but the period’s short – only 7 to 8 seconds – so it’s gonna be a bit mushy and disorganized. Moderate energy around 538 to 910, and light cross-shore winds make it bumpy. It’s a marginal call, nothin’ to get too excited about.
Sunday the 13th of September is another good one. Sunday arvo is the pick with a clean 6ft swell from the S, period of 10 seconds, and light cross-offshore winds. The energy’s moderate at 947, and with those clean conditions, it’s gonna be fun and rideable for a wider range of surfers. Monday the 14th gets blown out again with strong winds, so that Sunday arvo session is your next best bet after the Monday morning big one.
The second week (from the 15th onward) is a mixed bag. A lot of blown-out or tiny days with onshores and wind. Wednesday the 16th and Thursday the 17th are total losses – strong winds and flat or messy surf. Then Friday the 18th of September looks promising – a small but clean 3ft swell from the E with a light offshore from the NNW. That’s a good morning for a quiet, clean session on the smaller stuff, energy’s low at 227, so it’s a mellow one. The weekend after that looks sloppy again.
So, to sum it up: the absolute standout is Monday morning the 7th of September – that’s the one you want to circle on the calendar. Big, clean, long-period groundswell, wind off the land, and Cave Rock’s reef will handle it like a dream for the crew who can handle it. Sunday arvo the 13th is a solid backup for a more relaxed session. The rest is mostly fill or wind-swamped. If you’re a kiter, some of those windy, lumpy days (like Monday 14th) might look more interesting than for paddle surfers. Stay tuned – forecasts can change, and a blank run doesn’t usually last long here.
Rusty.

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