The Lowdown

Alright folks, Rusty here. Let's have a look at what's coming down the pipe for the next couple of weeks.

First up, we’ve got Cathedral Rock. This is a point break that’s fairly consistent, and it's looking like the main event for the whole period. The water's sitting at 57°F, which is about normal for this time of year, so nothing wild there.

The real story starts this Saturday afternoon, the 5th. We’ve got a big 15ft swell from the WSW, with a very long 15-second period. That’s a lot of energy pushing in (13,028), and while the wind is a cross-offshore, it’s a solid 16 mph, so it’ll be a bit bumpy but still rideable. This is a big groundswell, and at that size, this is expert territory for sure.

Sunday the 6th is where it gets interesting. The morning is a bit messy with a cross wind, but the afternoon is where it’s at. We’re looking at 8ft of SW swell, with a 14-second period, and the wind goes glassy. That’s a clean setup, though the energy is moderate (4,185). It’s a solid intermediate wave, but keep in mind the water is still a bit chilly.

The standout for the whole run, though, is Tuesday the 8th. Morning session, clear skies, 5ft of SW swell but with a very long 18-second period. That’s proper groundswell energy (2,288), and the wind is glassy. For a point break like Cathedral Rock, that long period is perfect – it’ll focus the energy and give you proper, lined-up waves. It’s not huge, but it’ll be clean and have that push. This is the one to circle on the calendar.

Now, the size goes up again around Wednesday the 9th, with 15ft swell from the SW, but the wind is a moderate cross-onshore and the energy is massive (26,650). That’s a lot of power, and it’s likely too big for this spot, making it a messy, choppy mess. Probably better for the kite crew than us paddle surfers.

We get a bit of a lull mid-week, with smaller, cleaner options on the 13th and 14th. The 13th has a glassy 5ft SW swell with a 16-second period, which is a nice, mellow day. The 14th morning has a clean 4ft offshore wind, but it’s a small one.

Looking further out, the second week has a few promising windows. The 16th has a 13ft WSW swell with a cross-offshore wind, which is a big, clean swell, but again expert territory. The real gem in the second week is Thursday the 17th. Morning has a glassy 12ft SW swell with a 16-second period, and the afternoon has a clean 10ft with offshore wind. That’s a solid, clean, powerful day for the experts.

The 18th and 19th are a bit of a washout with smaller, wind-affected waves, and the 20th finishes with a 12ft SW swell and a light cross wind, which is a decent end to the window.

So, to sum it up: the absolute best on offer is Tuesday morning the 8th for that clean, long-period groundswell at a manageable size. The second standout is Thursday the 17th for the big, clean, powerful swell. Everything else is a mix of big, messy days or small clean ones.

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.
