The Lowdown

Alright, let’s get into it. It’s a bit of a flat spell on the whole, if I’m honest. The next couple of weeks are looking pretty lean, so temper your expectations.

The only spot with any real pulses of energy is The groyne, a reef setup here that’s fairly consistent but you’ve gotta pick your moments. Right out of the gate on Wednesday morning, we’ve got a small 3ft swell from the ENE with a period of only 8 seconds, which doesn’t bring much grunt. The combined energy is a weak 97, so it’s barely pushing through. The wind’s light offshore from the WSW though, so it’ll be clean, glassy-like. Water temp is sitting at 68°, which is just a touch under average for this time of year – nothing to write home about but not cold either. That Wednesday morning window is your best early bet; it’s surfable but very ordinary.

From Wednesday afternoon onwards, things go downhill fast. Thursday and Friday get messy with strong cross and cross-onshore winds ramping up 25 km/h. The swell bumps to 4ft on Thursday with a short, weak 6 second period and combined energy climbing to 186, but the wind chops it to bits. No quality there.

The weekend is more of the same – Saturday and Sunday morning show some increase, with Sunday morning pushing 6ft from the SE and energy hitting 268, but that’s coupled with a 30 km/h crosswind and a 6 second period. That’s more of a messy, lumpy mess than a surf. Not worth paddling out; honestly, the setup looks more interesting for kite surfing.

We then hit a solid gap. From Monday the 31st right through to Tuesday the 10th of September, it’s a long stretch of poor conditions with tiny waves (1ft to 3ft) and mostly onshore or cross-onshore wind. The energy drops into double digits or low triple digits – weak stuff. The only glimmer is on Wednesday morning the 2nd of September, where we get a glassy 3ft swell from the ENE, period 9 seconds, and energy of 124. It’s clean, but small. Surfbale but ordinary again. And then on Saturday morning the 5th of September, there’s another glassy window with a tiny 2ft ENE swell, period 10 seconds, but the energy is only 49 – barely a ripple.

If you’re desperate, that Wednesday the 2nd morning is the standout, just because it’s glassy. But there’s no real size or punch in the whole 16-day run. A lot of flat days in between.

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.
