The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer at The Groyne over the next couple of weeks.
Well, I’m not gonna lie to you, it’s a pretty grim start. We’ve got a long stretch of nothing much happening. The first few days are just a write-off – poor conditions, rippy winds, and messy little waves. You’re looking at a gap of about a week before anything even gets close to worthwhile. The first real glimmer of hope doesn’t show up until Wednesday, the 2nd of September.
Even then, the standout is really just that one morning. Wednesday the 2nd of September is the pick of the whole outlook. The Groyne wakes up with glassy conditions, no wind at all, and a clean 6ft swell rolling in from the east. The water temp is sitting at 68°, which is about 1° cooler than normal for this time of year – nothing unusual, just a touch on the fresh side. The combined energy is a solid 483 (moderate), and with that 8-second period, it’s a decent little groundswell that should offer some shaped-up lines. This is the one to circle.
After that, Thursday the 3rd of September morning is also worth a mention. You’ve got 5ft swell from the east-northeast, with glassy conditions again. Energy is a more modest 257, but still enough for a fun session. The wind is barely a whisper, so the surface will be clean – just how we like it.
The rest of the period? Honestly, not much to get excited about. The wind swings around and gets messy, the swell drops off, or the period gets too short and jumbly. The week of the 4th to the 8th sees everything fizzle out into tiny, weak, or blown-out surf. By the 8th of September, you’re looking at a pathetic 1.0ft with a long 10-second period, but no energy behind it (16). That’s a lake, not a surf break.
So, if you’re keen, you’ve got two clean windows – Wednesday morning the 2nd, and Thursday morning the 3rd. After that, it’s back to waiting for the next pulse.
Stay frothing,
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.
