The Lowdown
G’day, Rusty here, lookin’ at the forecast for Off The Wall, and let me tell ya, it’s a mixed bag of absolute gems and some real ugly spells. This is a reef break for advanced surfers only – it’s a consistent spot that knows how to handle a proper swell, but you gotta pick your moments.
The water’s sitting at a chilly 56°F, which is a whopping 5° colder than normal for this time of year, so you’ll be wanting a good 4/3 and booties if you’re heading out. We’ve got a big run of swell coming, but the wind’s gonna be the boss.
The first real standout fires up on Wednesday, September 2nd. Wednesday morning is looking deadset clean with a 10ft SW groundswell rolling in at a long 13 seconds. The combined energy is pumping at 3169, and with a light S cross-off breeze, Off The Wall will be groomed and hollow. This is one of the best on offer, but it’s strictly for the experienced crew. The afternoon holds up nicely too, but the morning is the pick.
Now, Thursday, September 3rd, starts off okay with a 6ft WSW swell, but Thursday afternoon turns into a write-off. A 31 mph SE near gale rips in, making it near impossible to paddle into.
Friday, September 4th, is also a washout with the same brutal wind. Saturday, September 5th, sees a drop in size to a 6ft SSE short-period swell, but with a clean offshore breeze, it’s rideable for the desperate.
But then, Sunday, September 6th – hold onto your board. The morning is a standout session. We’re looking at a 8ft SW groundswell with an extremely long 18-second period, and the wind is glassy. The energy is a massive 3495, and this is groundswell perfection. The sets will be pumping, and the lineup will be clean. Expect crowds because this is the best window in the whole forecast. The afternoon turns cross-on and messy, but get that morning session.
The following week gets a bit patchy. Monday, September 7th, is a write-off with onshore wind. Tuesday, September 8th, drops right down to a 3ft SSW swell – small and clean in the morning, but nothing to get excited about.
Wednesday, September 9th, brings a nice 5ft SW swell with clean cross-off winds, and the energy is 938. It’s a solid, fun day. Thursday, September 10th, is similar with a 6ft WSW swell, but the wind is cross-shore in the morning, so aim for the afternoon.
The real promise for the second week shows up on Saturday, September 12th. The afternoon session brings an 8ft SSW groundswell with a 14-second period, and it’s a fresh offshore wind. The energy is a whopping 3642 – this is a serious swell. It’s a solid option for experts.
Sunday, September 13th, keeps the size with an 12ft SW swell, again with clean offshore winds, but it’s marginal with tide. The energy is 3761. Monday, September 14th, is a similar story – an 12ft S swell in the morning with gentle offshore wind, energy at 3854.
After that, the wind turns ugly. Tuesday, September 15th, has a tiny 4ft SSE swell in the morning with glassy conditions, but it’s a quick drop. Wednesday, September 16th, through the end of the forecast is a disaster – strong onshore winds and giant, messy swell. The 12ft SW swell on Wednesday afternoon has a massive 5386 energy, but it’s blown out and unsurfable.
Overall, the best true standouts are the Wednesday, September 2nd, morning and the Sunday, September 6th, morning. The Saturday, September 12th, afternoon and Monday, September 14th, morning are also promising for the second week, but keep an eye on the wind. This is a spot for the committed, and she’s gonna deliver.
Rusty.
