The Lowdown
Alright, let’s break it down for the next couple of weeks. Look, the first week is a proper struggle. The Breakwater-St Ives is an inconsistent point, and the wind is just ugly – cross-onshore, lumpy, choppy stuff. The swell energy is only moderate, reading 449 on the Wednesday morning, and it fades to nothing by Thursday. That’s a solid five-day gap with no decent surf. You get a little bump on Friday the 11th, but the wind is still all wrong, so don’t bother. It’s a long, frustrating wait.
Now, Tuesday the 15th of September is the real deal. The morning is flat calm – glassy as a mirror – with 6ft of west-northwest groundswell running at a 12-second period. That’s proper energy (1016), and the water is about average for this time of year. It’s going to be clean, lined-up, and perfect for this point. The afternoon stays clean with a light cross-off breeze, though the swell drops to 6ft. Crowds can show up here sometimes, but that morning window is worth the early alarm.
After that, Wednesday the 16th gets blown out again. Then Thursday the 17th throws a massive 13ft swell from the west-northwest with a long period of 11 seconds. That’s an insane amount of energy (3950), but I’ve got to tell you – that’s way too big for this break. It looks clean, but it’s an expert-only zone if you even think about it. The swell is just too heavy.
The second week has a few glimmers – Saturday the 19th has an 8ft west swell and clean cross-off wind, but the conditions are marginal with the tides and the wind picking up. The energy is still solid at 1165, but it’s not that Tuesday magic. The Sunday after that is big and clean again, but at 10ft, it’s only for the brave. All in all, that Tuesday the 15th is your one real standout. Don’t miss it.
