The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a rough start. The first proper chance to get wet doesn’t show up until Tuesday the 22nd, and even then, it’s pretty average. We’re looking at a solid week of mostly poor conditions with wind and chop mucking things up.
The one spot on the radar is Cave Rock (a reef break), and honestly, it’s not looking great for most of the period. The water is sitting at a nice 73°F, feeling a touch warmer than normal for this time of year.
Let’s run through it. Tuesday the 22nd morning has some 4ft swell from the SE with a 12-second period, but the NE wind is already up. It’s cross-shore and the energy is moderate at best (645). By the afternoon, the wind picks up and it gets messy. Wednesday and Thursday are the same story – onshore winds and chop, with swell dropping to 3ft. The scores are in the toilet.
Friday the 24th is a warning flag. We get a jump in size – 8ft from the S – but it’s a short-period windswell (9 seconds) and the wind is howling cross-onshore at 22 mph. That’s a lumpy, blown-out mess. That combined energy is a whopping 1287, but it’s all for nothing with that wind. Too big for beginners and ugly for everyone else. Honestly, with that setup, it looks more interesting for kite surfing than paddle surfing.
We get a slight reprieve on Saturday the 25th morning. 5ft from the SSE, 9-second period, with a light NE cross-shore at 6 mph. It’s still only marginal, but the conditions are cleaner. That’s your best option for the whole first week, but don’t expect magic.
The rest of the first week and into the second week is a write-off. Sunday the 26th drops to 2ft, and the wind is howling. There’s a long stretch from the 26th all the way to the morning of Tuesday the 29th where the surf is either tiny or blown to pieces.
Now, for a glimmer of hope way out there. On Tuesday the 29th morning, a bigger swell pushes in – 8ft from the S with a 9-second period. The wind is a light ENE cross-shore at 6 mph, and the energy is strong (1285). The wave comment says it’s marginal, but this is the only time the stars almost align. However, that swell is over 8ft, so it’s expert-only territory at a reef. If you’re not a charger, stay well clear.
After that, it’s back to small, wind-affected conditions through the end of July and into the first few days of August. The morning of Tuesday the 4th of August shows some light WSW wind cross-off with 4ft from the E, but the consistency is lacking and it’s a late-season call.
Bottom line: this 16-day window is poor overall. Don’t get your hopes up. If you can’t wait, the Saturday the 25th morning is the only one worth a look for a clean-ish, average wave. The bigger stuff is for experts only and comes with wind issues.
Stay patient, the forecasts can change.

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.
