The Lowdown
Alright, let's talk about the surf at The Breakwater-St Ives. It's gonna be a mixed bag over the next couple of weeks, no doubt about that. We start off with a few rough days. Wednesday morning is chopped up with a cross-on breeze and 5ft of slop. Not great. That carries into Thursday and Friday with onshore winds and poor conditions. The swell energy is on the lower side, in the 400s (489, 422), but it just doesn't matter with the wind blowing all over it.
Saturday the 12th is a change. The wind turns cross-offshore and the swell cleans up. Morning brings 6ft from the WSW with a combined energy of 322, and the afternoon pushes to 7ft from the W (515). It's a bit raw, but it's clean and it's the best we've had so far.
But Sunday the 13th, that's the first real standout. Sunday arvo, the wind goes glassy. We're looking at 4ft of clean west swell with a 10-second period, and the energy is 270. That's a pure, clean, fun session. It's the one you want to be out for.
Monday and Tuesday are pretty flat and ordinary. Swell drops below 3ft, still clean but no power.
Now, the big one is the 16th of September. This is a real pulse. The morning has 8ft of west swell, and by the afternoon it's a solid 10ft with a combined energy of 1778. That is a lot of water moving. The period is short, though, around 8-10 seconds, and the wind is cross-offshore. This is a heavy, powerful, expert-only wave. At 10ft, this is not for the faint of heart. Beginners need to stay well clear.
The surf gets messy again for a few days after that. The 19th, though, is another good one. Saturday morning looks clean with a light cross-off breeze, 4ft of WNW swell, and a long 11-second period. Energy is up at 391. That's a really nice, clean-looking window.
Then it fades out. The last stretch has easterly winds and a lot of slop. The 23rd has some size again, with 8ft and a 13-second period, but the east wind will be strong, making it tough. For most, it's a skip.
So, if you’re picking your sessions, Sunday the 13th is the clean, fun one. And the 16th is the big, heavy, expert day. Don’t sleep on that Sunday glass.
