The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer for the next couple of weeks.
Honestly, I gotta be straight with you – it's a rough stretch. The entire 16-day window is looking pretty grim with no real standout sessions. We've got a solid nine days of poor conditions straight off the bat, with nothing worth paddling out for until the end of the period. The issue is a persistent cross-onshore wind that just won't let up, keeping the surf messy and choppy.
The only break in the forecast is The Groyne, a reef setup that usually handles a bit of swell. The water temp is sitting at 70°F, which is about average for this time of year, so nothing unusual there.
The wind is the real killer here. From Wednesday the 9th right through to the 23rd of September, it's blowing from the SE, SSE, or ESE, and it's almost always cross-onshore. That's gonna chop up whatever small swell we get.
We do see a little flicker of hope on the 24th of September – Thursday morning. The wind is due to swing around to a light NNW, which is a cross-offshore breeze. That's a big positive. The swell is a modest 4ft from the E, with a period of 9 seconds and a combined energy of 239 (moderate). Conditions are looking clean. But it's a long way off, so don't get your hopes up too high. Even then, the afternoon looks like it gets messy again.
For the rest of the time, the swell is small, the period is short, and that wind is just plain ugly. It's a waiting game, folks. Sometimes you just gotta let the ocean do its thing.
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.
