The Lowdown
Yo, Rusty here. Let's talk about what's coming up for Off The Wall.
Right off the bat, we've got some solid energy on the way. The water is sitting at 56°, which is a solid 5° colder than usual for this time of year – that's a significant chill, so don't forget the good rubber.
The first real action kicks off on Saturday, September 5th. We're looking at a 7 ft SSE swell with a 8-second period, which is a bit short-period, but it's coming in with offshore winds from the SE. The combined energy is moderate (709). It's not the best of the run, but it's a start, and the wind will keep it clean.
The standout window is Sunday, September 6th, through to Monday, September 7th. Sunday morning is the highlight. The swell jumps to 8 ft, swinging to the SW with a long 18-second period, pushing a massive combined energy of 3896. That's some serious groundswell. With a light offshore breeze, this is going to be exceptional for experienced surfers. The long period means it'll wrap in nicely on this reef, with long, clean lines. Absolutely the best on offer. Sunday afternoon holds well at 7 ft with a 16-second period, still excellent.
Monday morning, the 7th, is a real treat. The swell drops to 7 ft from the SW, 14-second period, and the wind goes glassy from the NNW. That's almost a perfect scenario for this break – clean, lined-up, and powerful. The combined energy is still strong at 1522.
After that, we see a drop-off. Tuesday the 8th is still fun with a 3 ft swell and glassy conditions, but it's a big step down from the weekend. Wednesday through Friday is a write-off – small, weak, and poor winds.
But then, get ready for another pulse. Thursday, September 10th, sees a big increase with a 10 ft SW swell and a 15-second period, combined energy of 4539, and gentle offshore winds. This is for the brave and experienced only – 10 ft is big, heavy, and not for the faint of heart. The wind holds offshore through Friday, so it'll be powerful and clean.
The weekend of the 12th and 13th brings another solid run. Saturday, September 12th, has 8 ft to 8 ft SW groundswell, 16-second period, and moderate offshore winds. The combined energy is massive (3026-3379). This is another top-tier day for experienced surfers. Sunday the 13th is still good but the winds turn cross-on, so it's a bit rougher.
The following week gets messy. A big 10 ft W/SW swell on Tuesday, September 15th, is accompanied by a strong 28 mph cross-on wind. That's kitesurfing territory, not paddle surfing. It's a mess.
We then have a few days of moderate energy and clean conditions around the 17th, but nothing like the earlier standouts.
The very end of the period, Sunday, September 20th, is a wildcard. A huge 12 ft SW swell with a 14-second period and a combined energy of 9933 is on the charts. The wind is cross-shore with rain showers, so it's going to be a chaotic, powerful, and challenging beast. A true expert-only session if you're willing to take the beating.
So, for the best of it, don't miss Sunday, September 6th through Monday, September 7th. That's your window for the cleanest, most powerful waves. The second stand-out is Saturday, September 12th, for another dose of heavy, clean groundswell.
Rusty.
