The Lowdown

Alright, Rusty here. Let’s have a look at what we’ve got on offer.

Honestly, it’s a pretty grim run for the next two and a half weeks. There’s very little to get excited about. The surf is small, the wind is almost never in our favour, and most of the time the conditions are just plain poor. If you’re desperate for a paddle, there are a couple of brief windows early on where the ocean lays down flat, but don’t expect any quality.

The best chance for a clean wave comes on Tuesday morning, 12 August at The groyne. We’re talking a tiny 2 ft swell from the east, with a period of 9 seconds – so a bit of groundswell energy, but not much punch. The combined swell energy is weak at 79. The real winner here is the wind: dead calm, glassy conditions. That’s a rare treat. The water temp is sitting at 69°, which is about 1° cooler than average for this time of year, so nothing wild, just a touch fresh. It’s an intermediate reef break, fairly consistent, with the optimum swell from the southeast. The east swell is a bit off-angle, but with glass it’ll be clean. Expect crowds sometimes.

After that, the wheels fall off. From Wednesday 13 August right through to Monday 24 August, it’s mostly cross-onshore winds and choppy, lumpy conditions. The swell stays between 2 ft and 7 ft, but with short periods (5 to 8 seconds) and dirty wind, it’s not worth your time. The energy builds into the moderate range and then strong by the 18th (521), but the wind ruins it. Even when the swell bumps up to 10 ft on Monday 24 August, it’s cross-onshore and messy – that’s expert only and not clean.

There’s a tiny glimmer on Tuesday 25 August morning: 6 ft from the east, period 9 seconds, with light cross-on wind and the comment says “marginal.” The wind is light, so it might be rideable, but it’s still onshore and choppy. Not a standout, just a maybe.

So honestly, if you can get out on that Tuesday morning the 12th, do it. Otherwise, it’s a long wait with nothing to write home about. This is one of those stretches where the forecast will likely change, but for now, don’t hold your breath.

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.
