The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of surf coming up at Cathedral Rock, a classic point break that’s fairly exposed to the dominant SSW swell. The water temperature is sitting at a normal 57° for this time of year, so nothing wild there.
The main event is a monster pulse arriving on Monday, August 24th. That’s the standout. We’re looking at a 15ft swell from the SW with a 16-second period, which is a serious groundswell with massive energy (17330). That’s expert territory only – way too big for beginners. The wind is light offshore from the north, so it’ll be clean and lined up. This is a true big-wave day for those with the skills. The afternoon holds at 13ft with a 17-second period and light offshore winds, still a beast.
Leading up to that, we have some decent windows. Saturday morning, August 15th, is a nice little gem. 10ft SW swell, 15-second period, and glassy conditions. Energy is strong at 3812. That’s a great session for experienced surfers before the big stuff arrives. The crowd here is only sometimes an issue, but on a Saturday morning with that quality, expect a few others in the water.
The following week is a mixed bag. Sunday, August 24th, sees 7ft with a cross-onshore wind, so it’s a bit on the rough side. Monday, August 25th, is a return to clean conditions with a 8ft SW swell and offshore north wind, but by then the energy has dropped to 2261. It’s still good for experienced surfers. The rest of the week drops off into smaller, choppier surf with onshore winds, so the focus is really on that first weekend and the big Monday.
Stay safe out there, and don’t get too greedy on the big day. This is Rusty, signing off.

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.
