The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s cooking for the St Ives stretch over the next couple of weeks.
Honestly, the outlook is a bit of a mixed bag. We’ve got a run of poor conditions for the first week or so, with only a few windows where it might be worth a paddle. The water temp is about average for this time of year, nothing to write home about.
The standout, if you can call it that, looks like Wednesday afternoon on the 12th of August. The Breakwater-St Ives (a point break that’s fairly exposed to the NW) will have a 3ft swell coming from the west with a period of 9 seconds. The wind will be light and offshore from the south, so the face should be clean. Combined swell energy is moderate at 139. It’s not pumping, but it’s surfable. The break is inconsistent, so you might have to be patient, and it can get crowded sometimes.
The next best option is a long way off, on the 27th of August, Thursday morning. There’s a solid 10ft swell from the west with a 10-second period, and the wind is a strong cross-off from the WSW. The combined energy is a massive 2849, so there’s plenty of power. However, this is over 8ft, so it’s for experts only. The forecast is far out, so treat this as a promising but uncertain prospect. The swell direction is a good match for the break’s optimum NW direction.
For the rest of the period, there are several days with no real recommendations. From the 14th through to the 26th, you’ll see a lot of onshore winds, short-period slop, and generally poor quality. The surf quality is consistently rated as poor, with winds often cross-on or onshore, making it choppy and messy. There are a few days with clean conditions, like the 19th, but the swell is too big and the wind is too strong, making it more of a kite session than a paddle. On the 20th, with a 10ft swell and 28 mph winds, it’s definitely blown out and dangerous.
So, in short: keep your eyes on Wednesday afternoon for a small, clean wave, and maybe mark your calendar for the 27th if you’re an expert looking for a big, powerful groundswell. The rest is a write-off.
Rusty.
