The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for Cave Rock over the next couple of weeks.
First off, the water’s running a bit colder than usual for this time of year—about 1° cooler, so you might want an extra mil or a hood if you’re out there for a session. That aside, the forecast is a bit of a slow burner. There’s nothing worthwhile for the first few days. Monday the 14th and Tuesday the 15th are a write-off with strong cross-shore winds and tiny, messy waves. You’d be fighting a losing battle.
Things start to look a little more interesting by Wednesday the 16th morning. The wind swings light and offshore from the SSE, and we’ve got a 6ft swell from the east at 10 seconds. The combined energy is moderate at 608, but it’s still a marginal call—tide might mess with it. That afternoon, forget it: strong cross-onshore wind blows it out.
Thursday the 17th isn’t much better—light onshore winds and the swell hanging around 5ft to 5ft with the same east pulse. Combined energy is moderate at 606 to 900, but the quality isn’t there.
Now, Friday the 18th is where it starts to get good. Early morning, we’ve got a clean 12ft swell from the ESE, period 9 seconds. That’s decent size, pushing into expert-only territory for sure—over 8ft. The combined energy is strong at 3405, and with a light cross-offshore breeze, the waves should have some shape. The afternoon drops a bit to 10ft from the SE, still clean but with a moderate cross-offshore breeze. That Friday morning slot looks like the standout of the whole run.
Saturday the 19th sees the swell still solid at 10ft from the SE, period lengthening to 11 seconds, giving it some extra push. Combined energy is strong at 1789, but the wind turns cross-shore from the NE at 16 mph, putting a bit of chop on it. Not as clean as Friday.
Sunday the 20th holds size around 8ft to 8ft from the east, but the wind is fresh cross-shore or cross-offshore. The afternoon session looks marginally better with a cross-offshore breeze giving some clean faces, but still not a top pick.
Monday the 21st brings a new pulse from the SSW. Morning is 7ft at 8 seconds with moderate cross-shore wind—just okay. But Monday afternoon? Watch out. A solid 13ft swell from the SSW at 10 seconds rolls in, with strong combined energy at 2985. That’s big, expert-only, and the strong cross-offshore wind keeps it clean. Another potential highlight, but you’ll need to know what you’re doing.
After that, the swell backs off through Tuesday the 22nd to Wednesday the 23rd, with onshore and cross-shore winds messing up the 8ft to 6ft waves. The later part of the window, from the 24th onward, is poor. The swell drops below 3ft, periods get short, and the wind stays strong and cross-shore or onshore. Combined energy is weak to low moderate—nothing worth paddling out for.
So, the two standout moments are Friday morning the 18th with a clean 12ft ESE swell and light cross-offshore breeze, and Monday afternoon the 21st with a big 13ft SSW groundswell and clean conditions. Both are for experienced surfers only. Crowds are possible here at Cave Rock, so get in early if you can.

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.
