The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way.
Straight up, this forecast is a tough one. We’re looking at a long, quiet run with very little to get excited about. For the next week and a half, we’re staring down the barrel of a whole lot of nothing. From Thursday the 23rd of July all the way through to the morning of Monday the 27th, it’s a write-off – poor surf, onshore winds, and no quality on offer.
The first real flicker of hope comes on the morning of Monday the 27th. Back Strands will see the swell drop a little, but the wind swings to a cross-off from the SSW at just 9 mph. That will clean things right up. We’re looking at waves around 4 ft from the WNW with a moderate combined swell energy (276), but it's only rated as marginal. It’s not going to be pumping, but it’ll be the first sessionable option in days.
Stay patient though, because the real standout is shaping up for the afternoon of Thursday the 30th of July. The wind goes glassy—straight-up glassy—from the WNW at 3 mph. The swell is still small, around 3 ft from the WNW, with a 9-second period and a low combined swell energy (126). It’s small, it’s clean, and if you’re on a log or a funboard, you’ll be getting some of the most user-friendly waves of the whole 16-day window. Conditions like that are rare, and they won't last.
That little window of clean, glassy surf will carry over into the morning of Friday the 31st of July, too. Offshore winds from the SE at 9 mph, waves still around 3 ft from the WNW, with very low combined energy (75). It’s tiny, but it’s beautiful.
After that, it fades back to nothing. The wind picks up hard again, the swell disappears, and we’re left with poor, choppy, blown-out conditions right through to the end of the forecast on Friday the 7th of August. Kiteboarders might find some interest in those strong onshore days, but for a paddle surfer, this is the definition of a flat spell.
If you absolutely have to paddle, make the call for the 30th of July afternoon. It’s the cleanest the place is going to look for weeks.
Rusty.

Information about the Back Strands Surf forecast
The above surf forecast table for Back Strands provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Back Strands can be found by selecting the local surf guide option on the grey menu. Our Back Strands 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 (Back Strands) 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 Back Strands 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.
