The Lowdown

Alright, grab your wettie, let’s talk about what’s on the menu for Cave Rock.

Alright, look, I’m not gonna sugarcoat it – the next week and a half is a bit of a mixed bag. We’ve got some serious size coming through, but the wind is going to be a real bastard for the most part. The first few days, from the 8th through the 11th, are a write-off. We’re looking at a Saturday afternoon with a 5-foot swell from the ENE, but a howling 19 mph cross-off wind is just going to make it bumpy and horrible. Sunday and Monday get even worse, with a 10-foot swell on Monday morning from the south, but it’s pumping 25 mph cross-onshore – that’s just messy, dangerous, and honestly, better suited for a kite than a paddle. The combined energy on that Monday morning is a massive 1504, which tells you there’s a ton of power, but it’s all over the shop.

The real turning point doesn’t hit until the morning of the 15th. That’s when we get a little window of something special. The wind goes glassy – 3 mph from the ESE – and the swell is a clean 5-foot from the ESE with an 8-second period. The energy is moderate at 324, but that glassy surface is the key. It’ll be clean, fun, and the easiest paddling of the whole forecast. That Saturday morning is the standout for this entire window. The water temp is sitting at 71°, which is bang on average for this time of year, so no surprises there.

Then, Sunday the 16th morning is another beauty. The wind is glassy again, swell bumps up to 6-foot from the east with a longer 10-second period, and the energy is a solid 700. This is the best combination of size and clean conditions we see. After that, we get into a long stretch of marginal conditions. The swell stays in the 5-foot to 7-foot range through to the 20th, but the wind is mostly cross or cross-onshore, keeping things lumpy. It’s not terrible, but it’s not worth paddling out for unless you’re desperate. For the best of the best, you’re looking at the morning of the 15th and the morning of the 16th.

So, to sum it up: the first week is a washout. The 15th and 16th mornings are your golden tickets – clean, glassy, and fun. After that, it’s a slow fade into smaller, messier surf for the back half of the forecast. Don’t hold your breath for the 23rd – it’s just 2-foot dribble.

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.
