The Lowdown
Alright folks, Rusty here. Let’s break down the next couple of weeks at The Breakwater-St Ives.
Right off the bat, I gotta be straight with you – it’s a slow start. We’re looking at a solid stretch of nothing much from now until late in the month. For over a week, that northwest swell window stays pretty quiet, with waves mostly under 3 ft and winds constantly onshore or cross-onshore. The energy is weak, barely cracking 100 (26-139) on the combined scale, so don’t bother paddling out unless you just want a float in a wetsuit. It’s not until Friday the 21st that things lighten up.
Now, the one true standout in this whole forecast lands on Friday afternoon, the 21st of August. An east-southeast light breeze swinging just offshore is gonna clean this break right up. We’re looking at a 8 ft groundswell pushing in from the west-northwest with an 8-second period. That combined energy jumps to a solid 650, which is a proper shot of moderate energy for this spot. That’s the best on offer, and it’s not even close. Wave height over 8 ft though, so that’s expert territory – big, beefy, and for the crew who know what they’re doing.
The downside? The Breakwater-St Ives here is a point break that’s ‘inconsistent’ and only sometimes gets a crowd. You might get a few out, but with the size, it should spread out. That swell direction (WNW) is just northwest of the optimum, so the lines will come in, but they won’t be perfect. The period is short, under 8 seconds, so expect dumpy, quick waves that won’t wall up for long. Still, clean and big beats most days.
Other than that, the rest of the window is pretty grim. Saturday the 22nd sees a similar size (7 ft) but with a fresh westerly cross-breeze that’ll chop it right up, so no joy there. After that, it drops back to nothing again by Sunday. So the clear call is Friday arvo, and don’t hold your breath before that.
Rusty.
