The Lowdown
Alright, let's get this straight. The surf outlook for The Breakwater-St Ives is pretty grim for the next couple of weeks. I've scanned the whole 16-day window, and there isn't a single day that looks worth paddling out for. It’s a blank run, plain and simple.
We kick things off this Sunday morning, August 9th, with a tiny 1ft of weak WNW swell. The energy is bottom-of-the-barrel at 36, and there’s a cross-onshore wind messing things up. It’s just poor. That trend holds through Monday and Tuesday, with small, short-period swells and wind that’s either onshore or just isn't doing us any favors. The water temp is about average for this time of year, so nothing strange there.
We get a little bump in energy on Wednesday the 12th, with the swell jumping to 3ft and the combined energy cracking the 100s (132-136). That’s moderate wave energy, but the period is still short and the quality is rated as poor. Thursday the 13th sees the biggest swell of the first week, hitting 4ft with a period of 11 seconds. The energy gets up to 328, which feels like there’s something trying to happen, but the wind is cross-onshore and choppy, so it’s just a mess.
After that, it’s back to the doldrums. Friday through to the following Thursday sees a mix of weak, short-period swells from the N and W, with energy mostly below 150. The wind stays onshore or cross-onshore, making it all look like a waste of time. The break is inconsistent, and it’s living up to that reputation.
There’s a slight pulse of energy on Thursday, August 20th, with the swell reaching 4ft and energy hitting 231-263 from the WNW. But don’t get excited. The wind is blowing 19 mph from the NNE, and it’s onshore. It’s going to be lumpy, bumpy, and all over the shop. Not what you want.
The last few days of the outlook, from the 21st to the 24th, show a little more life in the energy readings, but the swell heights stay small and the winds are mostly onshore or cross-onshore. There’s just no clean window here. The quality never gets above "poor."
So, here’s the truth: there are no good surf options in this entire 16-day stretch. The Breakwater-St Ives is a point break that needs a specific window, and we just don’t have one. But keep the faith. Spots like this don't stay flat forever, and the long-range forecasts are always changing. One day soon, the stars will align, and it’ll be on. But for now, leave the board in the car and find something else to do.
