The Lowdown
Alright folks, Rusty here. Let’s get into it for the St Ives area. The next couple of weeks are a bit of a mixed bag, with a lot of flat spells and tricky winds, but there’s a couple of windows that could be worth a look.
First up, the only spot on the radar for this whole run is The Breakwater-St Ives, a point break that’s inconsistent and only occasionally breaks. It’s fairly exposed to swell, with an optimum direction from the NW. The water is sitting at 64°, which is a touch warmer than normal for this time of year.
We’ve got a rough start. From Tuesday the 4th right through to the end of the following week, it’s pretty grim. The swell is tiny, the wind is messy, and the surf conditions are poor. There’s a long gap of nothing good. You’ll see a bit of a bump on Wednesday the 12th with a 4 ft swell from the WSW and clean cross-off winds, but the energy is still weak (260) and the forecast says it’s ordinary. Thursday the 13th morning is a little better, with 4 ft from the WSW and clean conditions, but again, it’s not a standout.
The first real standout comes on Friday the 14th. The morning session is looking like the pick of the week. We’ve got a 6 ft swell from the WNW, glassy conditions, and the combined energy is moderate at 336. This is a proper point break, and with that long period groundswell, it’ll wrap in nicely. The waves will have some shape, and the paddling out should be easier between sets. It’s a bit of a wait, but that Friday morning is the one to circle.
As we push into the tail end of the forecast, things get a bit wild. The 18th of August sees a 8 ft swell from the W, with strong energy (1053), but the wind is onshore and messy. Then on the 19th, the swell jumps to 10 ft from the WNW, with very strong energy (1504). That’s expert territory, and the wind is cross-onshore, making it rough. That setup looks more interesting for kite surfing than paddle surfing, to be honest.
So, to wrap it up: the first week and a half is a write-off. The one and only true standout is the morning of Friday the 14th at The Breakwater-St Ives. Glassy, clean, and a solid 6 ft groundswell. After that, it’s either too big, too windy, or both. Stay patient.
Rusty.
