The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the St Ives area over the next couple of weeks.
Right off the bat, I’ve got to be honest with you – the first few days are a bit of a write-off. We’re looking at a stretch of ordinary to poor conditions from Tuesday the 1st right through to the end of the first week. The Breakwater-St Ives (a point break) is inconsistent at the best of times, and for the first four days, the wind is a cross-off breeze at 9 to 19 mph, which just isn’t doing us any favours. The swell is there, but it’s messy.
The real standout in this whole 16-day window is shaping up to be Saturday the 5th of September. That morning, the wind drops right out to nothing – we’re talking glassy conditions, just 3 mph from the NE. The swell is a clean 4 ft from the west, with a period of 10 seconds, giving us a combined energy of 279 (moderate). The water is sitting at 63°, which is about normal for this time of year. For a break that’s fairly exposed to the west, this is the best we’re going to get. The afternoon stays glassy but the swell drops to 3 ft – still a good session, but the morning is the pick.
Now, if you’re after a bit more size, keep an eye on Monday the 14th of September. That’s a full week and a half away, so don’t bank on it, but the signs are good. The morning looks clean with a light SE breeze at 6 mph, and the swell is 4 ft from the west with a long 12-second period. That’s a groundswell, and on a point break like this, it’ll wrap in nicely. The combined energy is a solid 675 (strong) – you’ll feel that. The afternoon is offshore and clean, same size. This one’s promising, but it’s a long-range call, so keep your fingers crossed.
The rest of the second week is a mixed bag. Tuesday the 15th is glassy but small, and Wednesday the 16th has onshore winds that ruin it. For experts, the morning of Tuesday the 8th of September shows a 8 ft swell from the west with a 9-second period and clean conditions, but the combined energy is 923 (very strong), which is a lot of power. That’s a heavy wave for the experienced crew only.
Overall, the standout is Saturday the 5th – glassy, clean, and a solid 4 ft. Get on it.
Rusty.
