The Lowdown

Alright, let’s get this done. Rusty here.

Honestly, if you’re looking for a solid surf window in the next 16 days, you’ll need a lot of patience. The whole period is a flat run with only a few small windows that are barely worth getting wet for. The first real surf we see won’t be until the 2nd of September, and even then it’s only marginal. There’s a gap of about 4 days with no recommendations at the start, so don’t plan a trip around this. The combined energy is weak to moderate on the best days, staying under 220 (moderate energy) for the most part.

The only spot in the mix is The groyne, a reef break. Water temp is running about 68°F, which is a bit colder than normal for this time of year, so a 3/2 wetsuit is the call.

Wednesday, 26th August (afternoon): Forget it. We’ve got a tiny 3ft swell from the ENE with a short period of 7 seconds, and a cross-shore wind. The combined energy is only 116 (weak). It’s poor out there.

Thursday, 27th August: Both sessions are a no-go. Morning sees 3ft, 8-second swell from the E with a 12 mph cross-shore wind, making it choppy and messy. Afternoon keeps the same swell but with a cross-onshore wind, even worse. Energy is moderate at 171, but the quality is poor.

Friday, 28th August: Morning is marginal. 4ft from the E, 7-second period, cross-shore wind. Energy is moderate at 220. It’s small and a bit lumpy but might be a knee-high option for the desperate. Afternoon drops to 3ft with onshore wind, so no.

Saturday, 29th August: Light rain, small 3ft swell from the E, 8-second period, and cross-onshore wind. Both sessions are poor. Weak energy at 117 and 130.

Sunday, 30th August: The swell bumps up to 5ft-5ft from the SE, but the period is short at 6 seconds, and we’re dealing with a fresh 19 mph cross-shore and cross-onshore wind. This is lumpy, messy, and honestly looks more interesting for kite surfing than paddle surfing. Energy is moderate (181-215).

Monday, 31st August: Back to 3ft from the SSE, 6-second period, with a moderate breeze. Poor all day.

Tuesday, 1st September: Drops to 2ft from the E, period stretches to 10 seconds, but the wind is cross-onshore to onshore. Energy is weak (133). Not worth it.

Wednesday, 2nd September (morning): This is the one standout we’ve got. The swell is only 3ft from the E, but the period is a solid 10 seconds, and the wind is glassy out of the north at 3 mph. That means clean, smooth conditions. The combined energy is 125 (moderate). For a small wave, this is the best shape you’ll see. It’s surfable, but very ordinary. Crowds are possible here, so you might not be alone.

Thursday, 3rd September: Back to 2ft-3ft, short period, cross-shore winds. Poor.

Friday, 4th September (morning): Another small window. 3ft from the ENE, 9-second period, with a light cross-offshore wind from the NNW at 3 mph. The water should be clean. Energy is 152 (moderate). It’s surfable, but the afternoon drops to 1ft.

Saturday, 5th September (morning): Glassy again, 2ft from the E, 10-second period. Very small, but clean. Energy is weak (67).

Sunday, 6th September (afternoon): The swell picks up to 5ft from the N, 6-second period, with a gentle offshore wind from the west. That’s clean. Energy is 145 (moderate). It’s only surfable, not great, but the wind is in your favour.

After that, the 7th to the 10th of September is tiny, with 1.0ft to 2ft swells, weak energy, and cross-onshore winds. There’s nothing to chase.

My call: The best on offer is the Wednesday 2nd September morning at The groyne. It’s small, but the glassy conditions and the 10-second period mean the waves will have some shape. If you’re desperate, the Friday 4th September morning or Sunday 6th September afternoon are your next best bets, but they’re nothing special. This is a slow period, mate. Don’t force it.

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.
