The Lowdown
Alright folks, it’s Rusty here. Let's be straight with you; the next couple of weeks around St Ives are looking pretty grim for a proper paddle. We’ve got a long stretch of poor conditions ahead, but there’s a couple of windows that might just get you wet.
The first real hope is on Saturday, 5th September. The Breakwater-St Ives will see a mixed-up 4.3ft swell rolling in from the WNW, with a period of 11 seconds. The wind is a cross-off, keeping things clean, but the vibe is marginal. The combined energy is moderate (415), and the water is sitting at 63.1°, which is about normal for this time of year. It’s inconsistent here, so don't expect a ton of waves, but it’s the only game in town for a session.
Then we get a big gap. Sunday the 6th and Monday the 7th see a jump in size, but it's a mess. A 7.2ft groundswell with a 13-second period hits Monday morning, but it’s laced with a cross-shore wind that’s going to chop it up. That’s proper powerful energy (1632), but it’s blown out. That much swell with that wind is more of a kite-surfing setup than a clean paddle. The following days are all cross-onshore and choppy, so we’re talking a solid week of poor surf.
The standout for the whole period actually falls on Thursday, 17th September. The forecast shows a 4.3ft WNW swell, with light winds turning glassy in the afternoon. The energy is light (277), but it’s going to be clean. The swell direction from the WNW is exactly what this spot likes. It’s a rare day of potential in a dry spell. Sunday, 20th September, also offers a clean cross-off breeze, but the waves are only 3.6ft and the energy is weak (225). It’s surfable, but nothing special.
So, in summary: the first week is a write-off. The best bet is to wait for Thursday, 17th September, for a glassy, clean session at The Breakwater-St Ives. It’s inconsistent, but it’s the only window that’s worth the paddle out.
