The Lowdown
Alright folks, Rusty here. Let’s get into it.
First up, the water temp at The Groyne is sitting at 68°, which is a bit colder than we’d normally expect for this time of year – about 2° cooler. It’s not a shocking chill, but you’ll feel that difference if you’re used to the usual July warmth.
Right now, we’re looking at a pretty quiet start. The surf is small and the wind is messy. Wednesday morning is glassy but the swell is only 2ft from the east with a short 6-second period – combined energy is a weak 36, so it’s not really doing anything. The rest of Wednesday and into Thursday is plagued by onshore winds and poor conditions. Thursday afternoon gets a bit bumpy with 12 mph cross-on winds. Friday brings a bit more size, up to 4ft, but that southeasterly wind is howling at 16 mph and the period is a pathetic 5 seconds, so it’s just a choppy mess. The combined energy jumps to 155 but it’s all windswell junk.
Saturday and Sunday don’t offer much relief. More onshore winds, rain showers, and small, short-period swell. The water is still that same cooler temperature, and the waves are just not clean. Sunday morning does see the swell push to 6ft, but with a 6-second period and strong cross-on wind, it’s a bumpy, closed-out affair. The combined energy hits 341, but it’s not quality energy – it’s just messy power.
The real turnaround doesn’t show up until Monday, August 3rd. The morning sees a clean 4ft swell from the east (7-second period), with a nice cross-off wind from the SSW at 9 mph. The combined energy is a solid 248 – moderate, but with good shape. It’s a “marginal” call, but it’s the first window that looks even remotely rideable. The best of the whole forecast though, and the only true standout, is on Thursday, August 13th. The afternoon session is the pick: glassy offshore wind from the WSW at just 3 mph, with a 3ft east swell running on a 11-second period. The combined energy is 251, and the conditions are clean. It’s not a big wave, but on a reef break like The Groyne, that long-period groundswell will line up nicely. The crowd factor is “sometimes” here, so you might have a few mates out, but with that quality, it’s worth it.
Between the start and that August 13th highlight, there are several days of poor to marginal conditions. The early week is a write-off, but once you hit the second week, there’s a chance for a few glassy mornings.
For the experts: the swell never really gets over 8ft, so it’s not a big-wave session. Beginners might find the 6ft Sunday a bit much, but the 2ft to 3ft days are fine if the wind ever cooperates.
Stay patient. The best window is that Thursday afternoon on August 13th – mark it.
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.
