The Lowdown
Alright, Rusty here from the North Shore. Let’s talk about the next couple weeks.
Thursday morning is a washout with 30 km/h cross-on wind and lumpy junk. Forget it. But Thursday afternoon the whole picture changes. The wind drops to a light cross-off, the swell is a clean 8ft from the SW with a 12-second period, and the energy is pumping. That’s the start of the good stuff.
Friday is the big one. Morning glass – no wind, 12ft SW groundswell with a 14-second period, and energy at 4555. That’s the best of the whole run. It’s a reef break, so that long period will wrap in perfect. It’s big, over 8ft, so this is for experienced surfers only. The afternoon holds just as clean at 10ft.
Saturday and Sunday keep it going. Saturday morning has a clean 7ft swell with a light offshore. Sunday morning is similar, 6ft and glassy. Water temp is about normal for the season.
Monday and Tuesday get wild. Monday morning has a 5ft SW swell with a very long 15-second period and a fresh offshore, but it’s marginal. Monday afternoon jumps to 13ft S swell with a short 9-second period and 5293 energy – that’s strong, but hard to paddle into. Tuesday morning is a monster: 55 km/h offshore wind, 12ft SW, 18-second period, and energy at 8732. That’s for experts or kite surfers only. Tuesday afternoon settles to a moderate offshore and 10ft.
We get a clean run from Wednesday the 29th through the 30th with 7ft and 6ft SW swells, then a drop. The first few days of August see smaller 4ft to 5ft surf, mostly glassy, but nothing special.
Then, on Wednesday the 5th of August, another spike. A 8ft SW groundswell with a 16-second period, light wind, and energy of 3224. That’s solid, clean, and for experienced surfers again. The following Friday the 7th of August brings a 10ft SW swell with a 13-second period and a light offshore. Another big one for the experts.
Crowds are possible at Off The Wall, especially on the glassy days, so plan accordingly.
This is Rusty, out.

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.
