The Lowdown
Alright, let’s talk about what’s happening in St Ives.
Honestly, the first week and a half is a write-off. Starting Thursday the 27th of August, clear through to the 6th of September, there’s just no surf worth mentioning at The Breakwater. We’re looking at strong winds, lumpy seas, and tiny, hopeless waves. It’s a long, frustrating gap for anyone wanting to get wet.
But hang in there, because the tail end of the outlook throws us a bone. On Monday the 7th of September, the morning shows a huge 12ft swell from the WNW. That’s a lot of water (1704 combined energy), but it’s too much for The Breakwater. You’d need to be an expert and even then, it’s dicey. The real highlight for that day is the afternoon session. The swell drops to a manageable 7ft from the W, and the wind goes light cross-off from the SW, promising clean conditions. That’s a good wave with moderate energy (763).
Now, Tuesday the 8th of September is the clear winner. You’re looking at 5ft of swell from the W. Beautiful. But the wind is the star of the show – true offshore from the SSW in the morning, shifting to SSE in the afternoon. That is going to groom those waves into perfection. The period is 11 to 12 seconds, so you’ve got some real groundswell energy behind it, giving the waves punch and shape. Combined energy is a solid 544-609. The water temp is around 63°, pretty standard for the time of year.
Just keep in mind that The Breakwater is a bit inconsistent, and you can expect some company in the water, as it gets crowded sometimes. It’s a point break, so it does handle that longer period swell well. If you can only pick one session, make it Tuesday. Unfortunately, the rest of the second week looks like it’s back to poor conditions, so don’t sleep on that window.
That’s the story.
