The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for the next couple of weeks.
We’ve got a solid run of groundswell on the way, but it’s one of those outlooks where you’ve got to pick your moments. The wind is the real story here, and for a point break like Cathedral Rock, clean conditions are everything. The swell rolls in consistently from the SW, which is right in the pocket for this spot, and the energy is serious. The combined energy values are mostly in the three- and four-digit range, meaning moderate to very strong wave energy. The water temp is about average for this time of year, nothing unusual there.
The real standout is Saturday the 12th. The afternoon glass-off is a dream, with 8ft of SW groundswell (15-second period) and zero wind. Glassy conditions on a point break with that much push is about as good as it gets. The morning of the 12th isn’t far behind either, with a light cross-offshore breeze and 10ft SW swell. That’s your best window for experienced surfers – solid, clean, long-period lines.
The week leading into it has some potential, but the wind is more onshore or cross on. Thursday the 10th and Friday the 11th have big 12ft to 13ft SW swell, but the onshore wind makes it a bit of a messy affair. Not the best for paddle surfing, but if you’re into kiting, that wind and swell combo might be more your thing.
After the weekend, Sunday the 13th is a nice clean-up. The morning offers a solid 6ft SW groundswell with a gentle offshore breeze from the NNW. That’s clean, lined up, and a good option for intermediate surfers looking for some fun.
Monday the 14th holds clean 6ft WSW swell, but the afternoon drops right off and goes cross-shore. Not worth the paddle then.
Then we hit a bit of a wild stretch. Tuesday the 15th sees a big spike in energy with 13ft SW swell, but it’s cross-onshore and choppy. That’s a lot of water moving around with messy wind – more for the experienced crew who don’t mind a battle.
From Wednesday the 16th through to Friday the 18th, the swell sits around 8ft to 12ft, and the wind starts to clean up again. Thursday the 17th and Friday the 18th are both looking clean with light offshore or cross-off breezes. That’s another solid run of quality surf.
Saturday the 19th has a moderate offshore breeze but the swell is dropping, and the wind is stronger. It’s still rideable, but not the best of the run.
There’s a lull on Sunday the 20th – swell drops to around 4ft, poor conditions, not worth talking about.
But then Monday the 21st and Tuesday the 22nd come back with a vengeance. Clean, 8ft to 8ft SW groundswell, light offshore or cross-off winds. That’s a really nice, consistent few days for experienced surfers.
The very end of the outlook, Wednesday the 23rd and beyond, shows a big 13ft SW swell on the way, but the wind is variable and cross-on. Energy is massive (over 9800), but the quality will be questionable. Keep an eye on that one, but it’s deep in the forecast.
So to wrap it up: Saturday 12th afternoon is your absolute best bet – glassy, 8ft, perfect. Thursday 17th and Friday 18th are also top-tier. The rest is a mix of good and average, with a few days best left for the kites.
Rusty out.

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.
Cathedral Rock is 52 km (32 miles) from the city of Geelong West. If you plan a holiday in Cape Otway, look for hotels and other accommodation in Geelong West. Geelong West has rooms for a wide range of budgets as well as car hire and transport links.
