The Lowdown

Alright, this is Rusty. Let's talk about what's on offer for Back Strands.

First up, the water's sitting at 62° - that's a touch warmer than normal for this time of year, which is a nice little bonus. You'll feel that difference.

Now, the honest truth is that the next few days are a write-off. We've got a bit of a gap on our hands. The only real window to get excited about is the very start of the run. Monday morning (July 27th) is your shot. We've got a clean 4ft swell rolling in from the WNW, with a period of 10 seconds. That's a decent groundswell, and with a light southerly breeze keeping it cross-off, the face is going to be clean. The combined energy is moderate at 346, so there's some push behind it. This is the standout, no question.

But after that, it goes flat pretty quickly. The swell drops and the wind turns onshore, bringing in lumpy, choppy conditions. From Monday afternoon right through to the start of August, there's just nothing to write home about. We're looking at a long, dry spell of about a week where the surf is either too small or too messy.

Things start to show a little pulse again on the 7th of August (Friday morning). We get a clean 3ft to 3ft swell from the WNW, with a long 9-second period. The winds are light and cross-off, so it'll be clean. The combined energy is moderate (129-146). It's not big, but it's surfable and clean – a decent option if you're desperate for a paddle.

Then, on the 8th of August (Saturday morning), the swell jumps up to 6ft from the WNW, but the period drops to 8 seconds. The combined energy is strong at 414, but a 6ft wave with a short period is going to be a bit of a lumpy, close-out mess, especially with that light cross-onshore wind. That size is pushing it for beginners, and the quality isn't there for the experienced crew either. It's a frustrating one.

Further out, the 10th of August (Monday morning) looks glassy with a 3ft WNW swell, but it's not much to get excited about. The 11th of August (Tuesday morning) offers a clean 3ft swell with a light offshore breeze, which is your best bet for the second week, but it's a long way out and the energy is weak.

So, to sum it up: Monday morning is the clear winner. Get on it if you can. The rest of the forecast is a story of waiting for the next real pulse.

That's the word from the sand.

Rusty.

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.
