The Lowdown
Alright, let’s get into it. The next couple of weeks here are a mixed bag, but there are a couple of days that really stand out. First up, the water’s a bit colder than normal, running about 57°F, which is a couple of degrees off where it should be for this time of year, so you’ll want the rubber.
Right now, we're looking at Sunday (30 August) at Off The Wall. Swell is coming in at 8ft from the SW with a long period of 12 seconds, but the overall vibe is marginal with questionable tides. It's clean enough with a fresh offshore breeze, but the combined swell energy is moderate (2019). Not the standout stuff, but a paddle if you’re keen.
Monday (31 August) sees the swell drop a bit to 7ft from the SW, still with decent period, but it’s cross-off and clean. Energy drops into the moderate three-digit range (1019). It’s okay, not great.
Now, here’s the standout of the first part of the window: Tuesday, 1 September. The morning session gets an 8ft SW swell at 13 seconds, cross-off wind with just a light breeze, and the combined energy jumps big-time into strong territory (2549). For experienced surfers only at this size—over 8ft is expert country. This is the session to circle. The SW direction matches the optimum for the break perfectly. Expect clean, powerful lines.
Tuesday afternoon swells up to 10ft, still from the SW but with a moderate cross-off breeze; still solid energy (3364) but for the hardcore crew.
Wednesday, 2 September, is another cracker morning: 10ft SW at 14 seconds, clean with a gentle cross-off, and very strong energy (3264). Again, experts only. This is the other real standout.
Thursday (3 September) morning sees a smaller 6ft WSW swell, glassy cross-off, still clean and good for experienced surfers (1394 energy). Afternoon goes downhill fast with a near gale from the SSE at 31 mph—don’t even bother.
From Friday (4 September) through Sunday (6 September), it’s mostly small with strong offshore winds that make paddling tough. Swell drops to 3ft to 5ft. Not worth the effort unless you’re desperate.
Then, we get a little window on Sunday, 6 September morning: glassy conditions, 5ft SW groundswell at 14 seconds—very long period. That very long period can make beach breaks a bit straight, but for a reef like this, it’s a treat. Light energy (847), but clean as glass.
The middle of the week (7-9 September) is small again—under 3ft to 4ft—with the odd glassy morning. Nothing to write home about.
Then, Tuesday, 8 September morning gives us a sudden jump: 5ft from the W at 14 seconds, clean, with solid energy (1004). Good for experienced guys.
The real long-range highlight comes on Saturday, 12 September. Morning delivers 8ft SW at 13 seconds with a gentle offshore breeze, and the energy is strong (2543). Afternoon holds the same size with a moderate offshore. Both sessions are “excellent” for experienced surfers. Crowds are possible here, so get in early.
The final standout is Monday, 14 September afternoon: a big 12ft WSW swell, 16-second period, cross-off wind, and the combined energy is very strong (5220). That’s a beast of a day, for experts only. The period is very long (over 15 seconds) so expect long lulls between bomb sets—makes paddling out a bit easier, but the waves will be powerful and heaving on this reef.
So, if I had to pick: Tuesday 1 September morning and Wednesday 2 September morning are your no-brainer standouts for quality and power. For the second week, Saturday 12 September and that Monday 14 September afternoon are the ones to watch, but a bit less certain this far out.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Off The Wall may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
