The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s happening at The groyne.

Right off the bat, I gotta be honest with you – the next week and a half is pretty grim. We’re looking at a long stretch of small, messy, or just plain poor surf. There’s a bit of a tease around early August with some moderate energy, but the quality’s just not there.

We start on Friday, July 31st. It’s a rainy mess with a southerly cross-breeze and a tiny 3ft ENE swell. The combined energy is weak at 150, and the water is sitting at 68°, which is a bit colder than normal for this time of year. The surf is poor, and that continues straight through Saturday and into Sunday, August 2nd. Swell picks up a little to around 5ft from the east, with the energy climbing to a moderate 254 by Sunday afternoon, but it’s all cross-onshore and choppy. Not worth paddling out.

Moving into Monday, August 3rd the swell drops right back. We see a long-period groundswell of 13 seconds come in from the SE, but it’s tiny at only 2ft. The energy is moderate at 376, but the comment says it all: "marginal." A long-period swell that small and straight is going to be tough to ride.

Now, a couple of mornings show a little promise. Tuesday, August 4th, we get a glassy morning with a slight breeze. Swell is only 2ft from the SE, period 9 seconds, and energy is low at 114. It’s "surfable but very ordinary." Then Wednesday, August 5th has a clean, cross-offshore southwesterly, with a 3ft E swell. Still small and not great. Thursday, August 6th is similar with a clean cross-offshore breeze but even less swell at 3ft.

After that, from Friday, August 7th all the way through to Saturday, August 15th, it’s a brutal run. For over a week, the swell barely breaks 2ft, and most of it is crummy onshore or cross-shore wind. Honestly, there’s a solid 7-day gap where surfing is basically a write-off. There are a few moments of glassy conditions, like on the morning of Sunday, August 9th with a 2ft E swell, but it’s just too small to get excited about.

The only flicker of something better comes right at the end. On Wednesday, August 12th, we get a clean offshore wind from the west, with a 2ft E swell that has a 10-second period. The energy is moderate at 102. Then Thursday, August 13th morning has a clean cross-offshore breeze and energy up to 142. And on Friday, August 14th morning, a light offshore from the west cleaning up a 2ft E swell with an 11-second period and energy of 114. It’s still small, but for this forecast period, that Friday morning, August 14th is the closest thing to a standout. Clean, better organised, but only for the dedicated longboarder.

The standouts for the whole period are thin on the ground. If you had to pick, that Friday morning, August 14th, at The groyne is your best bet. It’s a reef break, so it handles a longer period swell better than a beach would, and the wind is clean. Just don’t expect much size.

Rusty.

Information about the The groyne Surf forecast

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