The Lowdown

Alright, this is Rusty. Let’s get real about the outlook for The Groyne.

To be straight with you, the next 16 days look pretty grim overall. There’s a big gap of nothing worthwhile at the start, with the first real, but still poor, chance coming up on Wednesday morning, September 2nd. From now until then, it’s pretty much a write-off.

The first bit of a pulse we see is on Wednesday morning, September 2nd. The wind is dead calm, glassy, and that’s a major positive. But the swell is tiny, only 2 ft from the east with a period of 10 seconds. The combined energy is weak (66). You’ll be on a longboard, and it’ll be a real struggle to get a ride. The conditions are clean, but there’s just no push.

After that, the forecast drops off again. Thursday the 3rd and Friday the 4th see tiny, weak swell with poor wind. Late on Saturday, September 5th, the wind picks up from the northeast, blowing a fresh 19 mph, generating a lumpy 4 ft windswell. It’s a short period (5 seconds) and messy – more of a kite session than a paddle session.

The only day that might turn a head is Sunday morning, September 6th. The wind is light and clean from the northwest, and there’s a tiny bump of 4 ft from the north, but again, it’s a short period (5 seconds) and the energy is weak (80). The water temp is about 69°, which is a touch cooler than normal for this time of year, but nothing crazy.

The rest of the second week through to September 12th is a repeating pattern of tiny, weak swell, poor cross-onshore winds, and choppy conditions. The swell direction is generally from the east, which is okay for the reef, but the size and period just aren’t there. The Groyne is an exposed reef, but it needs a proper swell to work. This isn’t it.

Honest call: There is no standout. Don’t plan a session around this. It’s a long, flat, and choppy fortnight. The only silver lining is that forecasts can change, because it can’t stay this poor forever.

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.
