The Lowdown

Alright, surfers, Rusty here. Let’s get into the Crystal Ball for the next couple of weeks.

Right off the bat, we’ve got a solid pulse of southwest swell pushing in, so there’s no flat spell to start. The first really good window looks like Friday afternoon, with chest-to-head-high-plus sets rolling in. It’s a bit of a beast at 12ft on the face with a long 16-second pulse behind it, and the cross-offshore breeze should keep things reasonably clean. The energy is proper, with a reading of 6206, so there’ll be plenty of push. Water temp is 57°F, which is about normal for this time of year, so don’t stress about a major change.

Saturday morning is a bit of a mess with rain and stronger cross-off winds, but the swell is still there at 8ft. It’s the afternoon that really gets interesting here. That swell jumps up to a serious 15ft with a long 15-second period, and the energy is pumping at 13294. This is not a day for the faint of heart or for beginners – with waves this size, you need to know what you’re doing. It looks big and powerful, but that cross-off wind should keep some order to it.

Sunday drops back down to 8ft, but the wind swings more onshore, making things a bit lumpy. You can still find some fun ones, but it’s a step down in quality. Monday looks pretty poor with onshore winds and smaller swell. Tuesday, though, is a hidden gem. The swell is down but that long-period groundswell at 18 seconds is still wrapping in. The wind is glassy, which is a huge positive. It’ll be a bit smaller, around 5ft in the morning and 8ft in the afternoon, but those clean, glassy conditions will make it super fun for a mid-length or a log.

Then we get a big, raw stretch. Wednesday and Thursday bring a major pulse, with waves pushing 15ft and powerful 19-second energy in the water. But the wind is onshore and strong, making it a messy, blown-out mess. The combined energy readings are huge (15393 on Wednesday afternoon), but it’s not going to be surfable. Honestly, with that much size and wind, the setup at Cathedral Rock will be more interesting for the kite surfers than us paddle surfers.

Friday the 11th settles down to 10ft, but the wind is still onshore. A cleaner option arrives Saturday the 12th with light, cross-onshore winds, but it’s still not perfect. Then, look out for Sunday the 13th. The swell is a fun 7ft, with a clean offshore and light breeze. This looks like the pick of the second week, with clean conditions and glassy waves. Nice.

We get a bit of a lull early the following week, with smaller, wind-affected surf. But keep an eye on Saturday the 19th. The forecast is showing another solid pulse of 10ft swell, with a very long 19-second period, and it looks clean with cross-offshore winds. The energy is strong at 7777. It’s a long way out, so treat it with caution, but it has the potential to be the standout session of the whole fortnight. That long period will be best on the point, where it will wrap in nicely, so keep that in mind.

So to wrap it all up: Friday afternoon is your first call to get on it. The big daddy on Saturday the 5th is for experienced chargers only. And Sunday the 13th and Saturday the 19th are the promising, cleaner swells in the second week, though the 19th is one for the diary as the potential classic. Stay safe out there.

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.

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.
