Cathedral Rock Surf Forecast and Surf Report

Alright, let’s get into it. Rusty here, and I’ve got a good look at what’s coming down the pipe for us.

We’re starting off this Saturday, the 12th of September, with some proper juice at Cathedral Rock. It’s a point break, so it handles a swell like this real nice. We’ve got a solid 8 ft SW groundswell rolling in with a long 15-second period, and the wind is light and offshore out of the north. That combo is gonna put a smile on any experienced surfer's face. The water temp is sitting at 57°, which is pretty much what you’d expect for this time of year – no weird anomaly to worry about. The combined energy is pumping in at 3366, so there’s plenty of grunt in the water. This is a standout for sure.

Saturday afternoon holds at 8 ft, still from the SW with that same long period, and the wind swings to a light cross-off from the NW. Still clean, still excellent for those who know what they’re doing. Crowds can pop up here sometimes, so keep that in mind if you’re after a quiet paddle.

Sunday the 13th sees the swell ease back a touch – 6 ft in the morning with a nice offshore northerly at 9 mph. Clean lines, still good for experienced surfers. The afternoon stays clean with a moderate offshore from the NNW. A solid weekend overall.

Monday the 14th drops off a bit. Morning is a clean 4 ft cross-off, but by the afternoon it gets smaller and a bit crossed up. It’s still rideable, but nothing to get too excited about.

Tuesday the 15th turns a bit wild. The swell jumps up to 12 ft, but it’s coming with a strong cross-onshore wind. That’s gonna make it choppy and messy. The wave energy is huge – over 4000 in the morning and over 5000 in the afternoon – but the wind’s wrecking it. This is more of a spectacle than a good paddle.

We get a few days of tricky conditions through Wednesday and Thursday the 16th and 17th. The swell stays big, but onshore winds and some iffy wind states keep the quality down. Not the time to be picky.

Then we hit Friday the 18th, and things clean up nicely. Morning sees a 6 ft SW swell with a cross-off NW breeze, and the period stretches to a very long 16 seconds in the afternoon. Combined energy is 1890 and 1504 – solid, clean, and perfect for a point break like this. This is another standout window for experienced surfers.

The weekend of the 19th and 20th is a mixed bag. Saturday has a clean 7 ft with a moderate cross-off, but Sunday drops off and gets onshore. Not great.

Now, looking into the second week, there’s a real gem on Monday the 21st. The morning is glassy – dead calm wind from the south at just 3 mph – with a 10 ft WSW swell. Combined energy is 3600. It’s a big swell, so this is for experts only, but the glassy surface is a huge bonus. The period is 11 seconds, so it’s a solid groundswell for the point.

Tuesday the 22nd brings another big, messy pulse – 12 ft but crossed up. Not the one.

Then Wednesday the 23rd and Thursday the 24th look unreal. Wednesday morning is glassy with a 10 ft SW groundswell, period 15 seconds. Energy at 3687. Wednesday afternoon is also glassy at 8 ft. Thursday morning is completely calm – zero wind – with an 8 ft SW swell and 2706 energy. These are prime sessions for the experienced crew.

But the real standout of the whole 16-day window is Friday the 25th. Morning brings a massive 12 ft SW groundswell with a very long 19-second period. The wind is a light cross-off from the NNE. The combined energy is 7828 – that’s serious power. The afternoon drops to a still-impressive 10 ft with an 18-second period and a light cross-off. This is exceptional, expert-level surf. It’s a long way out, so there’s some uncertainty, but the potential here is off the charts.

The last two days, the 26th and 27th, see the wind picking up strong. Saturday the 26th has fresh to strong offshore winds – clean but tough to paddle into. Sunday the 27th goes massive again, with a 20 ft SW swell and energy at 14835, but the wind is moderate cross-off. That’s big, powerful, and only for the absolute top-tier experts, if anyone.

So, to sum it up: this spot has multiple standout sessions. The best on offer are the clean, glassy days on the 21st, 23rd, and 24th, and the absolute monster day on the 25th. The early weekend is also excellent. Get on it if you can handle the size.

Rusty.
