The Lowdown
Alright mate, Rusty here again. Let's talk about what’s cookin’ at Cathedral Rock.
The general vibe is a solid run of groundswell from the SW, but the wind is gonna be a bit of a chatterbox for a few days. The water temp is about 57°, which is dead average for this time of year. Nothin' to write home about.
Monday the 7th is a total loss. A 12 mph onshore wind and messy conditions. Steer clear.
Now, Tuesday the 8th is where you set your alarm. The morning is glassy with no wind, and a 5ft SW groundswell with a very long 18-second period. The wave energy is pumping at 2288. This is clean, lined-up, and only for the experienced lot. The afternoon holds up too, still glassy with a light SE breeze, and the swell bumps up to 8ft with a 17-second period, energy at 3103. This is your standout window.
Wednesday the 9th turns nasty. The swell jumps to 13-15ft, but a strong 15-18 mph cross-onshore wind will thrash it. It's big, dangerous, and messy – looks more like a kite-surfing playground than a paddle spot.
Thursday the 10th is still lumpy with a 9 mph cross-onshore wind and a 13ft swell. The energy is huge (8213), but the quality is poor. Leave it.
Friday the 11th morning glassy again with a light S breeze, and an 8ft SW groundswell at a 14-second period. Energy is 2606. Excellent for experts. The afternoon gets a bit bumpy, so get it early.
Saturday the 12th is a gem. Both morning and afternoon are glassy with an 8ft to 8ft SW swell. The period is a solid 15 seconds, and the energy is around 2300-2900. Clean, powerful, and all yours. Another top pick.
Sunday the 13th morning brings a 12 mph offshore wind from the NNW over a 6ft SW groundswell at 16 seconds. Energy is 1500, and it's clean. The afternoon fades, but the morning is worth a look.
Then the swell drops off. Monday the 14th has a 4ft SW swell but the wind is wrong, and the energy drops below 600. The week stays marginal with cross-onshore winds and 8ft swells. Not worth it.
Now, for the long-range banger. Sunday the 20th of September – the afternoon is the absolute pick of the whole outlook. A 10ft SW groundswell with a 16-second period, a light 6 mph cross-offshore wind from the NW, and a combined energy of 5751. That’s a big, clean, powerful groundswell. It's a standout, but it's over a week away, so keep an eye on it. The morning of the 20th is also good at 6ft.
Monday the 21st and Tuesday the 22nd still have clean 6ft to 6ft SW swells with light offshore winds. A nice end to the run.
So, the clear highlights are Tuesday the 8th and Saturday the 12th for the near-term, and Sunday the 20th of September afternoon as the big one to circle. Expect a crowd at Cathedral Rock sometimes, so paddle out early.
Rusty.

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.
