The Lowdown

Alright folks, Rusty here. Let’s get into it. We’re looking at a solid, extended window of surf at Gully’s, with the real magic happening in the mornings when the wind does its thing. The water’s sitting at a toasty 86°, which is a touch warmer than normal for this time of year, so you can get away with a spring suit or even just boardies if you’re tough enough.

The pattern starts quiet on Wednesday afternoon, August 26th – a weak, short-period S swell at 3ft with a cross-on breeze, so it’s a write-off. But hold tight, because from Thursday morning, August 27th, things start to turn. We’ve got a 1ft groundswell from the SW, but with a massive 18-second period, bringing plenty of energy (216). The wind is a clean cross-off, and the wave comment is solid. It’s small, but the shape will be there for a log or a fish.

The first real standout is Friday morning, August 28th. Glassy conditions, a 2ft SW groundswell with a 20-second period, and the combined energy is pumping at 543. It’s clean, lined up, and perfect for a longboard. The wind is dead calm, so expect silky waves.

Then, Saturday morning, August 29th, is the pick of the whole run. We’ve got a 4ft SW groundswell, 16-second period, glassy conditions, and the energy is nearly four digits at 937. The wind is completely calm, the waves will be clean, with some real push. The only thing to keep in mind with that long period is it might wrap a bit too fast for a beach break; it’s really going to shine at a point or reef setup. For a beach break, you might find it a bit walled up, but still, with that energy, it’s going to be a beautiful morning.

Sunday morning, August 30th, is another glassy session with a 4ft SW swell and 14-second period, energy at 795. It’s a rinse-and-repeat of good conditions. Monday morning, August 31st, drops off a bit with a smaller 4ft swell and a cross-shore breeze, but it’s still surfable.

We hit a rough patch on Tuesday, September 1st. The wind blows up hard from the SE at 22 mph, turning a 5ft short-period S swell into a lumpy, choppy mess. The setup looks more interesting for kite surfing than paddle surfing. That’s a day to sit out.

The next real highlight is Friday morning, September 4th. This one’s for the experienced crew. A 4ft SW groundswell with a 17-second period, glassy, and the energy is a massive 1119. The wave comment says “excellent surf conditions for experienced surfers.” The swell is packing a punch, and with that long period, it’s going to be powerful and fast. It’s a standout session, but if you’re a beginner, it’s going to be too much.

Saturday morning, September 5th, is another very good-looking morning, with a 4ft SW swell, 16-second period, and glassy conditions.

Then, we’ve got another big one on Thursday morning, September 10th. A 4ft SW groundswell, 16-second period, dead calm, and the energy is at 1034. The wave comment is “excellent surf conditions for experienced surfers” again. It’s a full-on, powerful groundswell with perfect conditions. That’s a date to circle on the calendar, but remember, it’s a long way out, so keep an eye on the forecasts.

So, for the best of the best: Saturday morning, August 29th, is the no-brainer standout for pure quality and glass. Friday morning, September 4th, and Thursday morning, September 10th, are the ones for the experienced crew looking for power. The mornings are your friend here, every time. The afternoons are mostly a write-off with onshore breezes, so make the most of the early sessions.

Rusty, out.

Information about the Gully's Surf forecast

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