The Lowdown
Alright, Rusty here, and I've been staring at the charts for The Wall. Let's be straight with you—this isn't a classic setup, but there's a little window of hope if you're patient.
We're looking at a long stretch of pretty average conditions. For the first week and a half, almost everything is "poor surf conditions" with tiny swell and dodgy wind. There’s a decent little pulse brewing, but you'll need to wait for it.
The first real chance of anything surfable shows up on Thursday the 27th of August. The swell is coming from the ESE with a combined energy of about 179 (moderate wave energy building). There’s a morning window with a clean 5 ft ESE swell. The wind is cross-off from the SW at 9 mph, so it’ll be clean. That afternoon drops to 3 ft, still clean and surfable but very ordinary. The period is a short 6 seconds though, so it’s windswell, not groundswell. Not a standout, but the best we’ve seen.
The real standout? Look at Friday the 28th of August. The morning has a clean 2 ft swell from the SE with an 11-second period—longer period means more shape. The combined energy is 117 (moderate), and with a light WNW cross-off breeze at 6 mph, it’ll be clean. For The Wall, this is as good as it gets in this forecast. Surfable waves, clean conditions, and a bit of period behind it.
Then again on Monday the 31st of August, we get a glassy morning. The swell is 3 ft from the ENE with a 6-second period, and the water will be glassy with a SSW breeze at 3 mph. Combined energy is 123 (moderate). It’s small and short period, but glassy and clean—great for a longboard on a light day.
A few quick notes for the rest of the run: the water temp is around 66°, which is about average for this time of year. The crowds at The Wall are "sometimes" an issue, so if you score a clean morning mid-week, you might have it mostly to yourself. For the second week from Tuesday the 1st of September, the swell picks up energy again (152-187 combined, moderate) but the wind stays cross-on and choppy, so it’s not worth getting excited about.
Best bet: Thursday morning the 27th or Friday morning the 28th of August for the cleanest, most rideable waves on offer.
Rusty.

Information about the The Wall Surf forecast
The above surf forecast table for 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 The Wall can be found by selecting the local surf guide option on the grey menu. Our The Wall surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (The Wall) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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 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.
