The Lowdown
Alright, this is Rusty, and I’m lookin’ at the only game in town for the next couple of weeks – Cave Rock. It’s a solid reef setup, advanced only, and it’s consistent, so it’s always got potential. But man, the weather and wind are gonna make us work for it.
Right now, water temps are about average for the time of year, so nothin’ wild there.
The forecast starts with a bit of a slow grind. Saturday the 15th through Monday the 17th, we’ve got chest-high waves around 5 ft pushing in from the east with a nice long 10 to 11-second period. The energy’s moderate, and the wind is cross-shore all day, and the reports are calling it marginal or even poor. It’s gonna be a bit choppy and messy—not the best, but you could pick a corner for a few.
Things go downhill from Tuesday the 18th through the 21st. Swell drops to knee-to-waist high, the wind turns cross-onshore, and the energy is weak. Just a flat spell really, not worth paddling out for.
Then we get a serious standout on Saturday the 22nd. The morning session is the pick of the whole forecast. We’ve got a clean 5 ft swell from the south, but the period is only 6 seconds, so it’s a bit short and weak. The wind is a light cross-offshore breeze, makin’ it glassy and clean. The energy is moderate. It’s the only morning in the whole window with a “good” call, so set your alarm.
Sunday the 23rd, hold onto your board. A massive 8 ft south swell rolls in with a very long 16-second period, energy is huge. But the wind is a strong cross-onshore at 28 mph, and it’s just blown out and messy. That’s expert-only territory, and even then, it’s more of a kite day than a paddle day.
The following week (24th to 30th August) looks bleak. Swell hangs around 6 to 7 ft on the 24th and 25th, but cross-shore winds and a lumpy sea keep it poor. By the 26th, it’s dropping fast, and the rest of the month is a mix of small, weak swell and onshore junk. A couple of glassy mornings on the 20th and 22nd are the only real bright spots in a long, frustrating stretch.
Bottom line: Saturday morning the 22nd is your best shot. It’s not perfect, but it’s the only clean window we’ve got. Otherwise, it’s a waiting game.
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.
