The Lowdown

Alright, surfers, Rusty here. Let's have a look at what's on the cards for The Groyne.

Alright, the honest truth is the next week and a half is looking pretty average. The water temp is sitting at 69°F, which is about normal for this time of year, so that's not the issue. The problem is we've got a long stretch of onshore, mostly cross-onshore winds, that are going to keep the conditions lumpy and choppy. It's not until we get into the tail end of the forecast that we see a real change.

We start off with a nothing burger. Thursday the 10th through to Sunday the 13th is all poor surf. The swell is there, but it's messy. We’ve got a moderate combined wave energy of 539 on Thursday morning, but it’s coming from the SSE at 22 mph, making it a fresh cross-onshore mess. The swell drops through the weekend, and the wind doesn't let up. It's a write-off.

The following week, from Monday the 14th to Wednesday the 16th, the swell gets smaller, dropping under 3 ft, and the energy is weak, with values like 54. The wind is still mostly cross-onshore, so it's just small, choppy, and not worth paddling out for.

The one glimmer of hope, and I mean a glimmer, comes on Friday the 18th in the morning. We get a glassy window with a light 3 mph wind from the NE. The swell is small, only 3 ft from the East, but it's clean. The combined energy is weak at 79, so it's not going to be any kind of standout, just a chance for a few grovelly ones. Saturday the 19th morning is a similar story, with glassy conditions and a 5 ft swell from the SSE, but that's a short period swell (6 seconds) so it'll be a bit fat and weak. The energy is moderate at 181, but the afternoon gets ruined by the wind.

Now, for the one that actually gets my attention. On Thursday the 24th, we finally get a proper offshore wind, a light WSW at 3 mph. The morning sees a 4 ft swell from the SE, with a moderate energy of 135, and it's clean. This is the best on offer in the whole 16 days. The swell direction is a good match for the break, and the offshore wind will make it smooth. It's not a big swell, so it's a good option for most, but the crowds will be *sometimes* an issue, so get in early. The afternoon holds a bit more energy from a longer period (10 seconds) groundswell, also from the SE, hitting 206, but it might be a bit shifty.

So, to wrap it up, it's a long wait for a clean day. The standout is definitely Thursday the 24th, with that morning window looking the cleanest. It's a long way off, so don't lock it in, but it's the one to watch. The Friday before that is just a grab-and-go if you're desperate.

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.
