The Lowdown
Alright folks, this is Rusty. Let’s have a proper look at what’s on the cards for The Breakwater-St Ives over the next couple of weeks. I gotta be straight with you – I’ve scanned the whole 16-day window and honestly, there’s no real day where it all comes together for a proper session. The swell energy is there at times, but the wind and conditions just keep ruining it. This is one of those painful runs where we’ve got to wait it out.
The first few days are a write-off. Sunday the 30th kicks off with a solid 6ft to 8ft WSW swell and a combined energy reading of 502 to 705 (moderate wave energy), but we’re stuck with a fresh cross-offshore wind and risk of thunderstorms. The water is 64°, which is about normal for the area. Monday the 31st gets even bigger – up to 10ft of W swell with a period of 10 seconds, energy hitting 1527 (strong wave energy) – but that’s all ruined by a fresh cross-onshore wind. That’s too big for beginners anyway and only for experienced surfers, but the chop will make it a mess.
Tuesday the 1st of September drops off to a tiny 4ft, with a light cross-off breeze making it clean, but it’s just ordinary, not worth paddling out for. Wednesday the 2nd bumps back up to 6ft to 7ft WSW swells, energy at 355 to 570 (moderate), but again the wind is fresh cross-off and the quality is poor. Thursday the 3rd is a similar story: 6ft W swell with a moderate cross-shore wind.
There is one brief flicker of hope late in the first week. Friday the 4th of September brings a 8ft W groundswell with an 11-second period (longer period) and energy soaring to 1369 (strong wave energy). The wind is cross-offshore at 19 mph in the morning, which could clean it up – but the forecast still calls it marginal, just questionable with the tide. It’s the closest thing to a standout in the whole run, but I wouldn’t get too hyped.
After that, the surf fades into nothing. From Saturday the 5th right through to Tuesday the 8th, we’re looking at 1ft to 5ft dribblers with poor conditions. The energy drops below 100 (weak) from the 6th onward. A few glassy mornings appear around the 12th of September (Saturday) with a 4ft W swell and a 9-second period, energy at 284 (moderate), but it’s only a small wave and the conditions are described as “expect good surf conditions” – still, it’s not worth the travel.
The bottom line: this is a two-week dud for The Breakwater-St Ives. No true standout, no clean big swell day. It’s a blank run that’s normal for the area when the winds don’t cooperate. Keep your eye on the charts – things can change.
Rusty.
