The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for The Groyne over the next couple weeks.

Honestly, mate, it’s a pretty bleak run. This is one of those stretches where you’re better off leaving the boards in the car and just having a walk along the beach. The whole 16-day window is pretty much a write-off for any kind of decent surf. We’ve got day after day of “poor surf conditions” stamped all over the data, so don’t get your hopes up.

Let’s break it down. The water’s sittin’ at 68°, which is a bit colder than you’d expect for this time of year – about a degree and a half off the mark, so you’ll feel that chill if you do paddle out.

Tuesday the 1st is a non-starter. Tiny 2ft E swell with a long 10-second period, but with onshore and cross-shore winds messing it up. The combined energy is weak, just 97, so there’s no power behind it. Wednesday and Thursday are the same story – small, messy, and choppy. The swell barely tickles 3ft on Thursday afternoon, but it’s a windswell with a period of only 4 seconds, so it’s all chop and no shape.

Friday the 4th through to Monday the 7th is more of the same drivel. Tiny waves, cross-shore winds, and energy readings in the 20s and 30s. Nothin’ to ride, really.

Now, we get a little spike on Saturday the 5th – the afternoon shows a 4ft NNE windswell with 107 energy, but it’s accompanied by a 19 mph cross-shore wind. That’s lumpy and ugly, not worth your time.

Thursday the 10th is the biggest swell of the whole run – 6ft from the SSE, with a solid 10-second period and 744 energy. That’s got some grunt, but the wind is a fresh 22 mph cross-onshore, creating lumpy, choppy conditions. This is a surf forecast that looks more like a kite-surfing day. The groyne’s a reef, so onshore wind at that size will make it a washout.

Saturday the 12th morning has the only “marginal” rating of the whole period – 5ft SE swell with 9-second period and 506 energy. It’s a decent amount of water, but the wind is onshore, and the comment says it’s questionable tide conditions. If you’re desperate, you could go look, but don’t expect much. The rest of that week is just more choppy, onshore junk.

So there you have it. A blank run. Very few consistent days, and the one or two that have any size get killed by the wind. This area tends to go quiet like this sometimes. Forecasts can change, but right now, there ain’t a single standout day.

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.
