The Lowdown
Right then, let's have a look at what's coming up for The groyne.
Honestly, for a spot that's a reef setup, this run looks pretty grim for a while. There's a big gap with nothing worthwhile on offer. The first real chance you've got isn't until Thursday the 3rd of September, and even then, it's tiny.
The water temperature is sitting at 69°, which is about average for the time of year. Nothing to write home about.
For that Thursday morning, the 3rd, you're looking at tiny 1ft waves from the east, with a period of 9 seconds. The wind is a light, offshore breeze from the north, which will keep the surface clean, even though the energy is weak (52). It's surfable, but it's very ordinary. The afternoon turns choppy again, so the morning is the only time to bother.
Friday the 4th morning is a repeat: tiny 1ft east swell, clean with a light cross-offshore breeze from the NNW. Again, very ordinary but clean. Energy is still weak (55). The afternoon gets lumpy again.
There's a bit of a spike in size on Saturday the 5th afternoon, with a messy 5ft NNE swell, but the wind is howling onshore at 22 mph, making it a complete write-off for surfing. Kite surfers might be interested in that blow, but for a paddle, it's a no-go.
Sunday the 6th morning offers a tiny 3ft NNE swell, clean with a light cross-offshore, but it's weak (67) and small.
The pick of the bunch, if you can call it that, is Monday the 7th afternoon. You've got a clean 1ft easterly swell with a true offshore wind from the west at 9 mph. It's glassy and clean, but you'll be fighting for scraps on a 9-second period. Energy is very low (27).
There are a couple more days with clean offshore winds on the 8th and 9th, but the swell is barely a ripple at 1ft. The 8th afternoon has a long period swell (14 seconds) from the SE, but it's still tiny and weak (48). That longer period might make it a bit more interesting at a reef, but there's no power behind it.
Honestly, for a reef that needs a good SE swell, this window is a drought. There's nothing that stands out as a true session. Keep an eye on the charts, it can't stay this flat forever.

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.
