The Lowdown
Alright, mates, let’s get into it. The forecast kicks off this Saturday, August 8th, and we’ve got a solid 16-day run ahead.
We’re talking about Cathedral Rock, a point break that’s fairly consistent. It loves a good SW swell, and the ideal direction is SSW, so everything from the SW and WSW is right in the zone. The water’s at 57°, which is bang on average for this time of year.
The real standout is Thursday, August 13th. That morning, we’ve got a massive 15 ft swell from the WSW, with a 15-second period pushing a huge amount of energy (15,154). The wind is light and cross-off from the WNW, keeping it glassy. This is expert-only territory – way too big for beginners. It’s a true groundswell, and with that long period, it’s going to be a freight train at this point break. The afternoon is solid too, but the wind swings a little more cross, so the morning is the call.
Next up, Wednesday, August 12th is also a ripper. 12 ft from the SW, 16-second period, and a massive 9,955 combined energy. The wind is cross-off from the WNW, keeping it clean again. This is a big day, but it’s a hefty one for experienced surfers only.
The first Saturday and Sunday (August 8th and 9th) are pretty ordinary. Saturday morning has 6 ft SW swell with a light offshore, but it’s a bit of a messy energy. Sunday gets blown out with 16 mph winds, so don’t bother.
Monday, August 10th has a great morning: 7 ft SW, 19-second period – that’s a very long period groundswell. Clean and cross-off. That’s a standout session for the more experienced crew. The afternoon gets ruined by rain and 16 mph cross-onshore winds, so get out early.
Tuesday, August 11th is a solid 7 ft SW swell, but the wind is cross-off, and the energy is moderate. It’s a decent day but not the absolute best.
Wednesday, August 12th and Thursday, August 13th are the big guns as I mentioned. After that, Friday, August 14th drops to 12 ft, but the wind is cross-on, so it’s a bit messier. Still big, but not as clean.
Saturday, August 15th is a glassy morning with 8 ft SW swell. That’s a beautiful window – clean lines, but the afternoon gets an onshore wind, so make the most of the morning.
Sunday, August 16th is a bit smaller at 7 ft, with a light cross-onshore breeze. Not a standout, but it’s a fun size.
Monday, August 17th has a glassy morning, 7 ft SW swell, and a 14-second period. Clean and smooth. That’s a great session for intermediates.
Tuesday, August 18th is all about the afternoon: 4 ft SW, but with an 18-second period and a cross-off breeze. That’s a long-period groundswell on a point break, so it’ll be lined up and clean. A sneaky good session.
From Wednesday, August 19th through to the end of the forecast, it’s a steady run of 5 ft to 8 ft SW/WSW swells with mostly clean winds. Nothing monstrous, but the Saturday, August 22nd afternoon stands out: 7 ft SW, 17-second period, and a gentle offshore wind. That’s a beautiful, clean, long-period swell.
The Sunday, August 23rd morning has a 7 ft WSW swell, but the wind is 22 mph offshore. That’s a fresh breeze, but it’s offshore, so it’ll be clean. It’s a bit wild, but for experts, it’s a fun, windy session.
Crowds at Cathedral Rock can show up sometimes, so on the best days, expect a few heads out. The spot is fairly consistent, so there’s always something to ride.
If I had to pick the absolute best: Thursday, August 13th morning is the king, and Monday, August 10th morning is a very close second.

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.
