The Lowdown
Alright, let’s get this sorted. The forecast for The Breakwater-St Ives over the next couple of weeks is a real mixed bag, so we gotta pick our moments.
The first week is mostly a write-off, if we're being honest. The wind just doesn't want to play nice. Wednesday the 9th has that 5 ft west swell, but a cross-onshore breeze chops it right up. Thursday the 10th morning drops off to almost nothing. The afternoon jumps back up to 7 ft, but it's super short period and the wind's howling. It’ll be a messy one.
Friday the 11th and Saturday the 12th don't offer much more, just onshore slop and choppy conditions. It's not a pretty start.
But then, look at Sunday the 13th. That’s our window. The swell settles in at 5 ft from the west with a decent 10-second period. More importantly, we get a light south-west cross-offshore wind, and the forecast flags it as clean. That's the call for the week. It’s the standout, no doubt. The energy reading is solid, showing there's some proper push in the water. It'll be a bit inconsistent given how this spot is, so you'll need to be patient, but the waves that come through will be worth the wait.
After that, the middle of the week just fades out. Monday the 14th and Tuesday the 15th have tiny surf, knee to waist high at the very best, and the wind is just okay. Not really worth paddling out for unless you’re desperate for a splash.
Now, hold on to your hats for Wednesday the 16th. The swell jumps to a solid 10 ft, but this is a serious warning. The wind is cranking in at a strong onshore 25 mph, and the wave energy is enormous. This is not a paddle-surfing day for The Breakwater. With that much swell, that much wind, and the break setup here, it's looking far more interesting for the kiters than anyone with a paddle in their hand. Get the camera out and watch the show from the sand, or stay home. It’s only for the brave, and by brave I mean foolish.
The rest of that week is just ordinary. Small, choppy, nothing to write home about. Things try to pick up again on Sunday the 20th, with a building swell reaching 8 ft in the afternoon and a cross-offshore wind that will keep it clean. That will be a heavy, powerful swell so you need to know what you're doing. The period is a bit on the short side though, which could make it a bit lumpy and walled. It's promising, for sure, but it's far out, so we treat that one as a “maybe”.
Looking further into the final stretch, there are some fun-looking days. Monday the 23rd and Tuesday the 24th show clean, glassy conditions with light offshores and a consistent 4 ft to 4 ft of west swell with a nice 11-second period. That looks like it could be a fun, clean finish to the outlook. But again, that's over a week away, so don't book the time off work just yet.
Yeah, so overall, this spot’s saving grace is Sunday the 13th. Get in the water then. The rest of the time, it’s mostly a waiting game. The water temp is a touch warmer than normal for this time of year, sitting around 64°F, so it's not freezing at least.
So that's the picture. There’s some hope on the horizon, but the next week is gonna test your patience. Keep an eye on that Sunday forecast, it’s our best bet.
Rusty, out.
