The Lowdown

Alright folks, Rusty here. Let’s get into it.

The next sixteen days are a real mixed bag. We’re starting off with a decent pulse of swell, but the wind is gonna be a battle for the most part. There’s one standout window that’s worth planning around, but otherwise, you’ll be picking through the scraps.

The first real swell hits us on Tuesday, July 21st, with The groyne seeing a 8ft swell from the ESE. But the wind is a cross-on SE breeze at 15 mph, making the conditions poor and choppy. That wave energy is moderate at 1089, but it’s a rough one. That afternoon, it drops to 7ft, still cross-on and choppy.

Wednesday the 22nd is a little smaller, 6ft in the morning, but still cross-on with a light breeze. The quality is marginal. The afternoon stays poor.

Now, here’s the one to circle. Thursday morning, July 23rd. The swell drops to 4ft from the E, but the wind swings to a light SSW at 3 mph, which is a clean cross-off breeze. The wave energy is a moderate 214. The conditions are clean. This is the best the forecast offers. The groyne is a reef break, and with that clean wind and a manageable 4ft east swell, it’ll be a proper little session. The water temperature is about average for the time of year, so no surprises there. It’s a fairly consistent spot, but it can get crowded sometimes, so get in early.

After that, things get small and messy. Friday the 24th is 3ft with a cross-shore wind, poor. Saturday the 25th bumps up to 4ft from the ESE, but again cross-shore wind and poor. Sunday the 26th morning has a tiny 3ft, but a clean cross-off breeze – it’s surfable, but very ordinary.

From Monday the 27th all the way through to Friday August 1st, the swell is tiny – 0.7ft to 1ft. The wind is mostly cross or cross-on, and the conditions are poor. There’s a brief moment on Thursday July 30th morning with a 1ft swell from the ESE and a 14-second period, glassy conditions, but it’s just too small to get excited about. The same goes for Friday July 31st morning – a glassy 1.0ft.

Then we hit a gap of a few days with no real hope. Saturday August 2nd is tiny and cloudy.

But hold on, Monday August 4th brings a shift. The swell bumps to 4ft from the ENE, and the wind turns offshore from the WNW at 12 mph. That’s a clean, moderate offshore. The wave energy is 110. It’s surfable, but still ordinary. That trend continues into Tuesday August 5th, with a 3ft ENE swell and offshore winds, but the period is a short 5-6 seconds, so it’s a bit wobble-headed.

The real takeaway? Thursday July 23rd morning is your best bet. After that, it’s a long stretch of tiny, wind-affected surf until the first week of August, when a clean offshore window appears but with very short-period swell. It’s not a classic run for the groyne, but the forecasts can change.

Rusty out.

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.
