The Lowdown
G’day, Rusty here. Let’s have a look at what’s on the cards for The groyne (reef) over the next couple of weeks.
Honestly, it’s a pretty bleak run. There’s nothing on offer for the first several days, and the whole 16-day window is looking ordinary. The groyne is *fairly consistent* normally, so this is a real dry spell. The water temp is sitting right around average for the time of year at 70°, so nothing unusual there.
We start off Thursday the 10th with a messy 8 ft SE swell, but a solid 22 mph cross-on wind makes it a total write-off. The energy is moderate (698), but that wind just ruins it. Friday the 11th through Sunday the 13th keep the same story: cross-on winds, lumpy and choppy, with swell dropping from 6 ft down to 3 ft. The combined energy fades from 366 to 90, and the period is short (6–7 seconds), so it’s weak and wind-affected.
Monday the 14th offers a tiny 3 ft swell with an onshore light breeze, but it’s still poor. Tuesday the 15th morning is the closest thing to a highlight – glassy conditions with a tiny 3 ft E swell (54 energy). It’s surfable but very ordinary. The rest of the week stays tiny and choppy.
Thursday the 17th sees a little bump to 5 ft from the ESE, but the period is just 7 seconds and the wind is onshore – still poor. The following week stays small, with a few glassy mornings on the 19th and 22nd, but the swell is barely there (2 ft–2 ft). The 20th has a 7 ft SE swell, but the wind is cross-shore or cross-on, and the period is short (6 seconds), so it’s marginal at best.
The real kicker is the 22nd: a 2 ft SE swell with a very long 11-second period. That’s groundswell, and at a reef break like The groyne, it could offer something clean if the wind plays ball, but it’s tiny and the cross-on breezes will still mess it up. The last few days of the month are a dribble of 1.0 ft to 2 ft with some cross-off wind on the 25th, but the swell is just too small to care about.
Bottom line: There’s nothing you’d paddle out for with any real enthusiasm. The groyne is exposed, but the wind is consistently wrong and the swell is either too small or too wind-affected. If you’re desperate, the glassy Tuesday the 15th morning is the least bad option, but it’s a long way from good. Might be one to skip.
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.
