The Lowdown

Alright, surfers, Rusty here. Let’s have a look at the stretch ahead. It’s gonna be a test of patience, that’s for sure, but there’s a little light at the end of the tunnel.

The forecast for The Breakwater-St Ives (Cornwall) over the next 16 days starts off with a whole lot of nothing. We’re looking at a dry spell for the first week, with a long stretch of flat, small, and messy conditions. The water's sitting at 65°F, which is a touch warmer than normal for this time of year, so at least it won't be a shock to the system when you get in.

For the first few days, through the 7th and 8th, we're dealing with tiny waves and onshore breezes. The swell energy is weak, down in the 20-50 range, and there's just nothing to get excited about. The swell period is long, around 9 seconds, but there's no height to back it up. Honestly, it's a good time to get the fins waxed and work on your pop-up on the lawn.

We stay in this funk right through to the 11th, with small, choppy waves and cross-onshore winds messing up any chance of a clean face.

Things start to stir a little on the 12th. The swell bumps up to around 3 to 3 feet and the energy jumps into the 126-169 range. It’s not big, but the wind turns cross-offshore and the conditions are clean. For a brief window on the morning of the 12th, it might just be surfable, but it's far from a classic. The Breakwater is a point break, so it can handle a bit of direction, but it's still pretty weak and ordinary.

That little pulse fades fast, and the 13th through 15th are back to blown-out and messy with onshore winds and small, weak swell. More time for lawn work.

Now, here’s where it gets interesting. On the 17th, a proper westerly groundswell rolls in. The energy meter just explodes, hitting 432 on the Monday morning and then a massive 1944 by the afternoon. The swell will be pushing 5 feet in the morning and up to 8 feet by the afternoon. The wind is cross-offshore and the conditions are clean. This is the standout of the whole period. It's a solid, powerful westerly swell, and The Breakwater will be handling it. With the size, it's definitely not for the faint of heart—this is one for the experienced crew. The period is around 8-10 seconds, so it won't be the most lined-up groundswell, but the energy is there. This is the one to circle on the calendar.

The 18th gets messy again with a strong cross-onshore wind messing up the 7-foot swell. The wave energy is still strong, but the quality will drop off quickly. Tuesday the 19th fades out, leaving us with a final blip on the 20th. We see an 8-foot W swell, but a strong offshore wind and a fresh breeze will be blowing it out. It's clean but blown-out, more for the advanced and the bold.

All in all, the 17th is your day. After a week of nothing, we get one powerful, clean window before it gets messy again. Don't sleep on it.

That’s the story from down here. Keep your eyes on that swell.

Rusty.
