The Lowdown

Alright, let me tell you how it is lookin' for the next couple of weeks here at The Breakwater-St Ives. First up, we got a bit of a wait on our hands. From now until the 12th of September, there is nothin' worth paddlin' out for. A real slow start to the run.

That Saturday, the 12th, sees some swell pushin' in, around 4 ft from the West with a short 8-second period. The combined energy is weak, just 263. But that cross-off wind from the SW at 16 mph is goin' to make things a mess. It's not onshore, but it's not your friend either. The surf will be poor. Saturday afternoon bumps up a bit to 6 ft, but the wind and chop are still a problem. Combined energy climbs to 421, which is moderate, but the quality just isn't there.

Sunday the 13th is a little better, but not by much. Still a cross-off wind, 6 ft swell from the West with a 10-second period gives a moderate energy of 592. It's surfable, but tide conditions might make it a bit of a head-scratcher. The whole thing is kinda "marginal" at best.

The rest of that first week, from Monday the 14th through to Thursday the 17th, is more of the same story. We got knee-to-waist high swell, but the wind is either cross-on or cross, and it's almost always choppy or lumpy. The water temp is about average for September, nothin' to write home about. It's just a tough stretch for a point break that likes a clean, offshore breeze.

Now, there is a highlight if you're patient. Friday, the 18th of September, that is your best shot. The swell is a little smaller at 5 ft from the WNW, but the period jumps right up to 13 seconds. That's proper groundswell energy, and the combined energy hits 613, which is solid moderate power. Wind is cross-shore and moderate, which isn't perfect, but it's way better than the onshore slop we had. It's inconsistent here, a spot that rarely lines up right, but this day has potential. For experienced surfers who know the lineup, this is the one to circle on the calendar.

After that, it fades fast. Saturday the 19th has clean conditions but weak, short-period swell. Then from the 20th onward into the end of the month, it's mostly tiny, weak swell with periods under 10 seconds. The wind turns offshore on the 25th, but the swell is barely a ripple—2 ft with a combined energy of 51. There's just not enough push.

The very last day, Sunday the 27th, a bump of 6 ft from the WNW pops up with a short 6-second period and a fresh cross-off wind. The energy is moderate at 304, but that period is so short, it'll be a washing machine.

So, to sum it up: the first week is a write-off. The second week has one real standout on the 18th. After that, it's small and slow again. The water temp is normal for the time of year, no surprises there. Keep your eyes on that Friday the 18th, and if you can get out there, it might just be worth the wait.
