The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming our way for the next couple of weeks.

To be brutally honest, this is a pretty grim outlook. We’re looking at a long stretch of poor conditions with hardly any windows worth paddling out for. The groyne is a reef setup that’s exposed to the swell, but the wind is just killing it day after day.

The water’s sitting at 68°F at The groyne, which is a bit colder than normal for this time of year – about 2°F below average, so you’ll want a good steamer.

The first week is basically a write-off. From Sunday the 16th right through to Friday the 21st, it’s all cross-shore and cross-onshore winds, with moderate to fresh breezes churning up lumpy, choppy conditions. Swell hangs around 4 ft to 7 ft from the SE and ESE, with periods of 6 to 8 seconds – short-period, junky windswell. The combined energy gets up to moderate levels (337 to 516), but it’s messy and blown out. No good surf here at all.

There’s a tiny glimmer on Saturday morning the 22nd. The wind swings NNW at 9 mph, giving us a clean, cross-offshore breeze. Swell drops to 4 ft from the east with an 8-second period, and combined energy is weak (188). The comment says “surfable waves but very ordinary conditions.” It’s not a standout, but if you’re desperate, it’s the only morning that looks remotely rideable. Crowds are sometimes an issue here, but with conditions this average, it might not be too bad.

After that, it’s back to the same story. Sunday the 23rd through the end of the month is a mess of cross-shore and cross-onshore winds, with poor surf conditions. Swell stays small to moderate, mostly 1 ft to 5 ft, and periods drop to 5 or 6 seconds in the second week. The combined energy is weak, often under 100. By Tuesday the 25th, we get a glassy morning with no wind, but the swell is only 2 ft – that’s barely a ripple.

Saturday the 29th and Sunday the 30th show a slight bump in energy (125 and 104), but it’s still poor quality with cross-onshore winds. Nothing to get excited about.

Overall, this is a long, blank run. The groyne is fairly consistent in picking up swell, but the wind just won’t play ball. If you’re a kite surfer, those choppy, windy days might look more interesting than paddle surfing. For the rest of us, it’s a waiting game. Forecasts can change, but right now, I’d save your energy.

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.
