The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for the next couple of weeks.
We’ve got a solid run of surf coming up, but it starts with a bit of a raw deal. The first few days are here but the conditions are a bit of a mixed bag. The real standout is looking like Monday the 17th of August, with some serious grunt and glassy conditions. There's also a promising pulse way out near the end of the window on Sunday the 23rd and Monday the 24th, but that's a long way off, so keep your fingers crossed.
Right now, we're looking at Off The Wall. It's a reef break, so it demands respect, and it's for the advanced crew. The water is a bit colder than normal for this time of year, sitting at 56°F.
Sunday 9th August – We've got a 12 ft SSW swell rolling in with a 12-second period, but it's messy. The wind is a strong SSE breeze at 25 mph, making it a cross-offshore. The combined energy is pumping at 3781, but it's a bit of a washout. Not the day to get excited.
Monday 10th August – The morning cleans up. A 10 ft SSW swell, 11-second period, with a fresh SE offshore wind at 22 mph. The combined energy is 3164. It's clean and offshore, but the size is big and the conditions are still a bit tricky. The afternoon picks up a strong offshore wind at 25 mph, which makes it hard to paddle into.
Tuesday 11th August – The swell drops to a more manageable 6 ft to 5 ft from the SSW with a 12-second period. A light breeze keeps it clean. The combined energy is in the 1100-1500 range. This is a good, solid day for experienced surfers, with clean, cross-offshore conditions.
Wednesday 12th August – This is where it gets interesting. A 6 ft SW swell with a very long 18-second period rolls in. The morning wind is light ENE, cross-offshore, and the combined energy is 2390. The afternoon goes glassy with a light SE offshore. The period is so long that the waves will be thick and powerful, with long lulls between sets. This is a proper groundswell. It'll be best at this reef, as a beach break might see it breaking too straight.
Thursday 14th August – The afternoon is a real treat. A 6 ft WSW swell with a 14-second period, and the wind goes glassy with a WNW breeze at 3 mph. The combined energy is 1582. This is a proper window of clean, lined-up waves.
Sunday 16th August – The morning is glassy again with a 5 ft WSW swell. The combined energy is 1003. The afternoon picks up a bit with a 7 ft swell and a clean cross-offshore wind.
Monday 17th August – This is the one. The morning has a 10 ft WSW swell with a 15-second period, and it's glassy as a mirror. The combined energy is a massive 3909. The afternoon stays glassy with a 8 ft swell. This is the best of the entire forecast. The size is big, but the conditions are perfect. Only for experts, but if you're keen, this is the session.
Sunday 23rd August – We start to see another big pulse. A 7 ft SW swell with a 15-second period arrives in the morning with a light, clean cross-offshore wind. The combined energy is 2570. The afternoon picks up to 10 ft, but the wind gets a bit stronger. This looks promising, but it's a long way out.
Monday 24th August – A solid 10 ft SW swell hangs around, with a 13-second period. The wind is clean and cross-offshore in the morning, with a combined energy of 2828. The afternoon stays clean. If this holds, it's another big day for the experts.
Overall, there's a lot of good water moving around. The absolute standout is Monday the 17th of August – glassy, powerful, and big. The long-range stuff on the 23rd and 24th is worth watching, but don't bet the farm on it yet.
Stay safe out there.
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. If you surf the same spot (Off 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 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.
