The Lowdown
Alright, let’s talk in feet, because that’s how we measure it. Cathedral Rock is the spot, and we’ve got a solid run of groundswell coming through, but you’ll have to play the wind right.
The pattern is a long period SW groundswell that’s going to pulse and build for over a week. The clean start is Tuesday morning the 21st with a 6ft SW swell at 13 seconds, a light cross-off wind, and the energy is there. The real standout is Thursday the 23rd through Friday the 24th. Thursday morning hits with a huge 13ft SW swell, a 14-second period, and the combined energy is massive. Friday the 24th is even bigger, pushing 15ft from the SW with a 15-second period, and the energy is off the charts. Friday morning is glassy with a light offshore wind. That’s your expert-only territory, way over 8ft, and the long period means the sets are well-spaced but powerful. This point break is the place for it.
Another standout session is Thursday the 30th of July. The afternoon sees a 10ft SW groundswell with a 15-second period, combined energy is huge, and a clean offshore wind from the N makes for exceptional conditions for the experienced crew.
The surf drops off after the 2nd of August, turning smaller and weaker. There’s a potential return on the 5th of August with a clean 8ft SW swell, but that’s a long way off, so keep an eye on it.

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.
