The Lowdown
Alright, let’s talk about what’s shaping up. The main spot is Cathedral Rock, a point break that’s got a good run of swell coming. It’s fairly consistent, and you can expect some company there when it’s pumping. The water’s sitting at about 57°F, which is pretty average for this time of year, so no surprises there.
The first real window opens on Saturday, August 1st. We’ve got a clean 6ft SW groundswell rolling in with a solid 17-second period – that’s some proper long-period energy that’ll line up nicely on the point. The wind is light offshore from the north, making for glassy, clean conditions. The combined energy is strong at 2001, so there’s plenty of push. This is a top pick for the near term, best for experienced surfers. The afternoon remains clean with a similar vibe.
Sunday the 2nd is even better. The swell bumps up to 7ft from the SW, still with a long 16-second period. The wind stays offshore, a bit stronger from the NNW at 15 km/h, keeping it clean. The energy is up at 2461, so it’s still powerful. This is the highlight of the first week – solid, clean, and consistent.
Come Monday the 3rd, things start to change. The swell is still a decent 6ft, but the wind goes cross-offshore from the WNW, and the period drops to 14 seconds. It’s still clean, but the quality dips. The energy is 1726, so not weak, but the wind isn’t as kind. The rest of the week into the 6th sees the swell dropping and the wind turning more cross-onshore, making for choppy, less appealing conditions.
Looking ahead, there’s a nice window on Friday, August 7th. We get a 5ft SW groundswell with a 16-second period, and the wind goes glassy in the morning from the north at just 5 km/h. That’s a magic moment, with the energy back up to 1993. The afternoon stays clean with a cross-off breeze. This is another standout, but as it’s a week out, keep it in mind as promising but not certain.
The early part of the second week, around Monday the 10th, looks messy with strong cross-onshore winds and poor conditions, so skip it. Then, mark Tuesday the 11th of August. The swell jumps to a solid 10ft from the WSW, and in the afternoon it goes completely glassy with the wind dropping to zero. The period is 14 seconds, and the energy is massive at 7226. This is a serious, powerful swell that’s only for experts. For a point break like Cathedral Rock, it could be epic, but it’s a big, raw swell. This is a true standout for the long-range, but it’s a gamble.
Wednesday the 12th stays big at 11ft from the SW, with a very long period of 18 seconds in the morning. The energy is through the roof at 9841. The wind is light cross-shore, so it’s not clean, but the power is immense. Expert territory only. After that, the wind turns more onshore and the swell hangs around the 8ft mark, but with messy winds making it a bit of a washout for the rest of the week.
So, the best bets are the opening weekend of August 1st and 2nd, and the glassy window on the 7th. The big swell on the 11th and 12th is a wildcard for the brave, but it’s not for everyone.

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.
