The Lowdown
G’day, Rusty here. Let’s talk about Cathedral Rock. The water’s sitting at 57°F, which is about normal for this time of year. The surf is coming from a long-period SSW groundswell, which is primo for a point break.
Sunday kicks off with a clean 6ft SSW swell at 15 seconds. Northerly offshore breeze keeps it glassy, and the energy’s pumping at 1308. A solid, rippable size for intermediates. The afternoon stays clean at 5ft with a light offshore.
Monday drops to 4ft in the morning. Still clean with a light cross-offshore breeze. The afternoon gets a bit lumpy, so the morning is better.
Tuesday gets punchy: 10ft of swell in the morning, but the cross-shore wind ruins it. Choppy. The afternoon hits 12ft with a cross-onshore – that’s a kiting day.
Wednesday through Thursday stays big, 12ft to 8ft, with onshore winds. Massive energy but poor conditions. Expert-only at best.
Now, Friday the 18th through Saturday the 19th is a standout. Friday morning has a clean 7ft SSW swell with a cross-offshore breeze. Energy is strong at 2378. The afternoon is 5ft with a 16-second period – long, lined-up waves. Saturday morning holds 7ft, clean. Crowds are possible, but the quality makes it worth it.
Sunday the 20th starts clean but a strong 30 km/h NW wind makes it tricky. Afternoon gets rainy and cross-onshore.
After that, a bit of a lull. Monday the 21st and Tuesday the 22nd are moderate and choppy.
But Tuesday the 22nd afternoon through Wednesday the 23rd is the absolute highlight. Tuesday afternoon sees 10ft of SW groundswell with a 16-second period, clean as glass with a light offshore. Energy is massive at 5183. Wednesday morning pushes it to 12ft, same clean conditions. This is the one to aim for.
Thursday the 24th and Friday the 25th are a write-off with strong cross-onshore winds.
Saturday the 26th and Sunday the 27th morning bring another clean run. Saturday has 6ft to 7ft with light offshore winds. Sunday the 27th morning is a cracker: 8ft of swell, a 17-second period, and a light cross-offshore breeze. Energy is 4457. That’s long, powerful groundswell at a point – magic. The afternoon gets messy.
Monday the 28th ends with big, choppy conditions.
My pick: the 22nd afternoon and the 23rd for the biggest, cleanest swell of the batch. The 18th and 19th for a more manageable size. The 27th morning for a long-period special. The middle week is hit and miss, but those days are gold.
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.

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.
