The Lowdown

Alright, this is Rusty. Let’s talk about the next couple of weeks at Off The Wall.

Right now, we’re looking at a bit of a slow, messy start. The first few days are pretty average – we’ve got some swell, but the wind is all over the place. For Monday and Tuesday, it’s mostly cross-onshore and choppy, with a moderate to fresh breeze messing things up. The combined energy is sitting around 580 to 630 (weak to moderate), so there’s not much to get excited about. The swell is coming from the SW and NW, but the short period on Tuesday is only 6 seconds, so it’s pretty weak and disorganised. Not worth paddling out for.

Things start to look up from Wednesday morning, September 16. The wind swings offshore from the SSE at 22 mph, which is a major positive for this advanced reef break. The swell is coming from the WSW at 7 ft and a solid 13-second period, so you’ve got proper groundswell energy. The combined energy jumps to 2528 (strong). This is a standout for experienced surfers only – 7 ft is getting big for beginners, and the strong offshore wind will make it clean but also make paddling a bit harder. The afternoon stays similar but a bit cleaner.

Thursday and Friday keep that offshore flow, but the wind picks up to 25 mph, making it strong and clean but a real challenge to get into the waves. The swell holds around 5 ft to 6 ft from the SW, with a period of 11 to 13 seconds. The combined energy stays in the 765 to 1472 range (moderate to strong). These days are marginal but still worth a look for advanced crew who can handle the power.

Now, the real window opens up on Saturday morning, September 19. Light offshore breeze from the SE at 6 mph, clean conditions, and a consistent 5 ft SW swell with a 12-second period. The combined energy is 1096 (moderate). This is a solid, clean session for experienced surfers. The afternoon stays clean with a gentle cross-off breeze. This is the best of the first week.

Sunday and Monday, September 20 and 21, keep the quality high. Light winds, clean conditions, and a steady 6 ft WSW swell with a 13 to 14-second period. The combined energy sits around 1116 to 1250 (moderate). Monday morning especially is a beauty – light offshore and clean. This is where you want to be.

Things taper off a bit on Tuesday and Wednesday, September 22 and 23, with the swell dropping to 5 ft to 6 ft and the wind picking up again. The combined energy drops to around 512 to 841 (weak to moderate). Still rideable but not as good.

Then, on Thursday, September 24, we get a surprise. The swell direction shifts to SSE and SE, with a shorter period of 8 seconds, but the swell height jumps to 7 ft in the afternoon. The combined energy is 1113 (moderate). The wind is light offshore from the SE, so it’s clean. This is a good option for experienced surfers, but the short period means the waves might be a bit fat and less organised.

The final weekend, September 26 and 27, sees a big pulse of SW swell hitting 8 ft to 12 ft, with a long 14-second period. The combined energy is massive – 3493 to 4041 (very strong). This is huge, powerful groundswell. The wind on Saturday is cross-off and clean, but by Sunday it’s strong offshore from the SE at 25 mph. This is expert-only territory. The size and power will be intimidating.

Finally, Monday, September 28, is the absolute standout of the entire forecast. Glassy, near-calm conditions with a light variable breeze. The swell is a solid 12 ft from the SSW with a 14-second period, and the combined energy is 4570 (very strong). This is a massive, clean groundswell hitting a reef break – a true big-wave session for experts only. The afternoon holds similar but with a moderate cross-off breeze.

The very last day, Tuesday, September 29, offers a glassy 6 ft SW swell with a 12-second period. Combined energy is 1427 (moderate). A nice, clean way to finish the period.

So, to sum it up: the best windows are Saturday September 19 through Monday September 21 for solid, clean surf in the 5 ft to 6 ft range, and then Monday September 28 for the real big-wave spectacle. Keep in mind, crowds are possible here, so expect company at these times.

Rusty.

The above surf forecast table for Off The Wall provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Off The Wall can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
