The Lowdown
Alright, let’s get into it. This is where we’re looking.
We’ve got a solid run of swell on the way for Cathedral Rock, starting from Friday morning, 28 August. It’s a point break setup that’s fairly exposed to the SSW, and we’re locking into a long-period SW groundswell over the coming days. The water’s sitting around 57°F, which is pretty much normal for this time of year.
Friday morning kicks things off with a clean 8ft SW swell, period around 13 seconds, and light cross-off wind from the west. The combined swell energy is noticeable at 4223, and conditions are looking excellent for experienced surfers. It’s not a beginner wave at that size. By afternoon, the wind swings onshore and things get a bit marginal.
Saturday morning is where it starts to clean up nicely. Glassy conditions, clear skies, and a 6ft SW swell with a longer 14-second period. It’s a drop in size but cleaner, which makes for a really fun session.
Sunday and Monday hold 8ft to 8ft SW swell, but Sunday’s wind is cross-on in the morning, making it a bit of a struggle. Monday however, Monday morning looks like the standout of the first week – glassy conditions, 8ft SW swell, 14-second period, and the combined energy is up at 2545. That’s going to be clean, lined up, and working well on the point.
Tuesday rolls in with stronger cross-off wind from the NNW, keeping the surface clean, and the swell stays at a solid 7ft with a long 16-second period. Best for intermediates and above.
Now, let’s talk about the big one. Friday morning, 4 September. That’s the standout of the entire run. We’re looking at a 16ft WSW swell, 14-second period, combined energy of 15034 – that’s very strong. Winds are cross-off and light, so it’s clean. This is exceptional surf for expert surfers only. If you have the skills, that’s the session you don’t miss.
The following days keep the swell pumping in the 12ft to 18ft range, but wind starts to get too strong or cross-onshore at times. Sunday the 6th afternoon has a nice window – 18ft SW swell, clean, moderate energy, but Monday the 7th is messy with strong cross-on wind and poor conditions.
By the 9th of September, the swell drops back to a manageable 7ft, glassy morning, excellent for experienced surfers. Then the 10th gives another beautiful window with 8ft SW swell and a very long 17-second period, glassy in the morning. That’s a proper groundswell, perfect for the point.
The last few days show another pulse – Saturday 12 September morning brings a 15ft SW swell with 14-second period and clean conditions, combined energy of 14495. That’s another one for the experts.
Overall, the best on offer is the Friday 4 September morning session for experts. If you want something a little less heavy, Monday morning 31 August and Thursday morning 10 September are both glassy, clean, and really fun for intermediate and above.
That’s how it’s looking from here.

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