The Lowdown
G'day, Rusty here. Alright, let's have a look at what's coming our way for the next sixteen days. It's a bit of a mixed bag for Off The Wall, and you're gonna need to pick your moments.
We kick off Wednesday the 16th with a solid 8ft SW groundswell, but don't let the size fool ya—that 22 mph SSE blow is strong offshore, making it a tough paddle and the conditions are pretty marginal. The energy is pumping though, reading 4019 (strong). Thursday the 17th is more of the same: strong offshore winds and messy conditions, so it's not a day for the faint-hearted. The real clean-up starts Friday the 18th morning. The wind eases to a moderate 16 mph offshore, the swell drops to a more manageable 5ft from the SW, and everything cleans up nicely. The energy is moderate (786), but the conditions are set for some good waves.
We get a little lull into the weekend, but Sunday the 20th morning gives us a bump back up to 6ft SW groundswell (1445 energy) with a fresh offshore breeze. The afternoon sees the direction shift a touch to WSW, keeping the energy up. Then, Monday the 21st is a real standout—we've got a 5ft WSW groundswell but the wind drops to barely a puff at 3 mph from the SE, making it glassy and clean. The energy reading is 545 (moderate). Conditions are saying "very good", and that's the kind of session you wait for. The water temp is about average for this time of year, no big anomalies.
After Monday, we hit a rough patch from Tuesday the 22nd through to Wednesday the 23rd afternoon. The swell drops, the winds get fluky or turn onshore, and the energy dips below 400. It's a dead few days. If you've been waiting, Thursday the 24th is your next solid look. We get a 8ft SSW groundswell with only a gentle 9 mph offshore breeze, making it clean and powerful. The energy jumps to 2457 (strong). This is expert territory at over 8ft, but for those that can handle it, it's excellent. Friday the 25th morning holds at 6ft SW with clean conditions, so a good follow-up session. The rest of the week fades a bit, but Sunday the 27th morning brings another very good window: 5ft WSW swell (1435 energy) with a gentle 9 mph offshore breeze. Clean and fun for experienced surfers.
The first few days of October see the swell drop right off, with tiny 2ft to 2ft waves and onshore winds, so the surf dries up completely until the very last record on Thursday the 1st of October morning, which is a tiny 2ft SW groundswell (228 energy) with zero wind—dead calm and glassy. It's small, but it might be the only thing moving for a paddle.
The standout for me? Look at Monday the 21st of September. You've got a solid 5ft WSW groundswell, 545 energy, and the wind goes almost dead calm from the SE. That's an offshore, glassy morning that will shape up beautifully. No crowds to worry about, but with conditions that good, they might come around.
Stay sharp, get out there when it's clean, and don't bother with the flat days.
Rusty.

Information about the Off The Wall Surf forecast
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. Our Off 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.

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.
