The Lowdown
Alright folks, let’s talk about The Groyne for the next couple weeks.
Thursday the 23rd is your one and only real chance in this whole run. Water temp is 68°, which is a touch below normal for late July – not crazy, but you’ll feel it’s a bit cooler than usual.
Thursday morning is the highlight. Clean 4ft easterly swell with an 8-second period. Wind is light out of the SSW, just a cross-off breeze, keeping things smooth. The combined energy is 208 (moderate), so there’s some grunt in the waves. The east swell is working well with the spot’s preferred SE direction. This is proper fun for any intermediate surfer on the reef. Crowds can pop up *sometimes*, but on a morning like this, it’s worth sharing the water.
Thursday afternoon goes glassy – wind drops to just 3 mph from the east, dead calm. Swell hangs around 4ft, but those mirror-like faces will have you grinning from ear to ear. Thursday is the day.
From Friday the 24th all the way to August 7th, it’s pretty grim. The wind turns onshore or cross-onshore and cranks up. Every session is marked as poor quality. There are some bigger pulses – like August 5th with a 8ft easterly swell and a combined energy of 705 – but the wind is howling straight onshore from the ESE at 12 mph. That’s just messy, choppy junk for experts only. The rest of us are better off waiting.
Bottom line: don’t waste the 23rd. After that, it’s a long dry spell of onshore slop and growing swell you can’t use. Things could change, but for now, Thursday’s your only window.
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.
