The Lowdown
Alright folks, Rusty here. Let’s break down what’s coming for Cathedral Rock. This is a point break that loves a SSW swell, and we’ve got a solid run of pulses heading our way.
First real surf worth getting wet for is Friday morning, July 31st. We’re looking at a clean 6ft SW swell with a 12-second period and a cross-offshore breeze out of the WNW. Water temp is 57°F, which is about average for this time of year. The combined energy is moderate (903), so there’s some fun, punchy waves to be had. It’s fairly consistent here, and you might see a few others out, but that morning session is a winner.
The big standout is the Saturday into Sunday window, August 1st and 2nd. Saturday morning serves up a clean 6ft SW groundswell with a very long 17-second period under a light offshore N breeze. The energy jumps into the strong range (2001), and the water is still comfortable. This is classic Cathedral Rock – long, clean lines, plenty of power, and that offshore wind will have the waves peeling nicely. Sunday morning keeps the fire burning with a solid 7ft SW swell, 16-second period, and a clean offshore N wind. The energy is strong (2460), and conditions are set for excellent surfing. At this size, it’s definitely for the more experienced crew.
The surf stays fun but gets a bit spotty through the middle of the second week. However, the real head-turner is the August 15th window. Saturday morning the 15th is looking like a big one: a 8ft SW groundswell with an 18-second period, clean cross-offshore NW wind, and extremely strong energy (4477). That’s a lot of water moving – long, powerful lines, definitely for experts only. The afternoon is just as good, with a 8ft SW swell, 17-second period, and a clean offshore NW wind, scoring top marks. That’s your second big standout, but it’s a ways out, so keep checking the updates.
There’s a bit of a dry spell in the middle of the second week, but the first weekend and that mid-August potential are the real deals.
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.
