The Lowdown
Alright, let’s talk about The Groyne in proper units. This is a reef setup, exposed to the east-southeast, and it’s a fairly consistent little spot for intermediate surfers. But I gotta be honest—through the next week, the conditions are mostly ordinary. The water temperature is 68°F, which is a bit colder than normal for this time of year, so you might want a spring suit.
Let’s start from Thursday the 27th of August. The morning is mostly cross-shore wind from the south-southeast at 12 mph, with small swell around 2 ft from the east, period of 8 seconds, and combined wave energy is weak (129). The surface is cross-chop, so not great. That afternoon, the wind goes cross-onshore from the southeast at 12 mph, swell picks up a little to 3 ft from the southeast, period drops to 6 seconds, and energy is still moderate (163). The waves are choppy—not worth paddling out.
Friday the 28th is similar. Morning sees a cross-shore breeze from the south at 9 mph, 3 ft swell from the east-northeast, 7-second period, and energy at 129. The afternoon brings a clean offshore wind from the east-southeast at 9 mph, with 3 ft swell from the east-southeast, period 7 seconds, and energy at 149, but the wave comment says poor conditions. So, no good window.
Saturday the 29th has light rain in the morning, cross-onshore wind from the south-southeast at 9 mph, small 2 ft swell from the east, 8-second period, and low energy (74). The afternoon is clear but still cross-onshore, similar small swell. No good.
Sunday the 30th brings a bit more energy. Morning cross-shore from the south-southeast at 16 mph, 5 ft swell from the southeast, 6-second period, and moderate energy (205). But the wind is moderate and it’s cross-chop. Afternoon is cross-onshore at 12 mph, 4 ft swell, energy 147. Still messy.
Monday the 31st is more of the same: cross-shore to cross-onshore, 4 ft to 5 ft swell, but the wind is moderate and the surface is choppy. Not the day.
Now, Tuesday the 1st of September calms right down. Morning light breeze from the south-southeast at 6 mph, 2 ft swell from the east, period 10 seconds, and energy drops to 98. The afternoon is offshore from the east-northeast at 6 mph, same tiny swell. Still poor.
Wednesday the 2nd of September is where things get a little interesting. The morning is glassy—wind from the north at only 3 mph, absolute flat calm. The swell is tiny, 2 ft from the east, period 10 seconds, and energy is very weak (59), but the wave comment says “surfable waves but very ordinary conditions” and it’s glassy. That’s the best the whole forecast period gets. It’s not going to be epic, but if you want to get out on a tiny, clean wave, this is your window. The afternoon kills it with a cross-onshore breeze.
Thursday the 3rd of September morning is clean with a light cross-offshore wind from the north-northwest at 3 mph, 2 ft swell from the east, 9-second period, and energy 76. The comment says “surfable waves but very ordinary conditions.” So another small, clean window. Friday the 4th morning is glassy again, but the swell is only 1 ft from the east, period 9 seconds, energy 37—super small.
From there, it’s the same story through the weekend and into the following week: small swell, weak energy, and mostly cross-shore or cross-onshore winds. The swell direction stays mostly east or east-southeast, which is fine for The Groyne, but the size never gets above 2 ft or 3 ft, and the energy is weak. The best windows are the glassy mornings on Wednesday the 2nd and Thursday the 3rd of September, but they’re only for those who love tiny, clean waves.
So, to be honest, there’s no standout day in the whole 16-day outlook. The surf is mostly small, weak, and wind-affected, with only a couple of very small, clean windows. If you’re desperate, aim for the morning of Wednesday the 2nd or Thursday the 3rd of September, but keep your expectations low. The rest of the time, it’s a washout.

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.
