The Lowdown
Alright, Rusty here. Let's have a look at what’s on the table for The Breakwater-St Ives. I've got the 16-day window in front of me, and I gotta be straight with you – it’s a bit of a grim stretch. We're looking at a long, blank run of poor surf.
The only spot in the mix is The Breakwater-St Ives, a point break that's known for being inconsistent. The water temp is sitting around 65°, which is a touch warmer than normal for this time of year. But that’s about the only good news.
We kick off on Saturday the 15th of August with a tiny 3ft swell from the W, with a short period of 8 seconds. The combined wave energy is weak, sitting at 115, and there's a moderate breeze blowing from the N and NNW. It's just poor all around. This sets the tone for the entire forecast.
Things don’t get any better through to the end of the first week. We see a small uptick in swell on Thursday the 20th of August, with 6ft from the WNW (moderate combined energy of 516) and a 9-second period, but the winds are a fresh cross-shore or cross-onshore, keeping things lumpy and chopped. The whole first week is a washout.
Heading into the second week, there’s a bit more size but zero quality. Saturday the 23rd of August brings 6ft from the NNE with a short 6-second period (energy at 308), but again, the wind is on it, making it choppy. Then Monday the 24th of August has 6ft from the N with a strong breeze blowing onshore at 25 mph. That’s blown-out, messy, and only for someone with a death wish. Nothing here cleans up.
After that, it all fades away. From Wednesday the 26th of August right through to the end of the window on Sunday the 30th, the swell drops off to under 3ft. The conditions are poor, with no decent surf. There is a brief moment on Friday the 28th of August where we get a tiny 2ft from the W (9-second period) and glassy conditions, but the wave energy is weak at 67 – it's barely a ripple. Not worth paddling out for.
Honestly, there's no standout here. Not one recommendation. This is one of those stretches where the ocean just switches off for the area. The forecast can always change, but as it stands, it's a solid blank run with nothing to get excited about.
Stay patient.
