The Lowdown
Alright, folks. Rusty here again, but this time in feet and miles.
We’ve got a bit of a mixed bag on the horizon. The first few days are a write-off, with messy, lumpy conditions and poor surf quality. The real action starts to build from Thursday morning, August 13, and that’s where we’ll see the best of it.
The standout session is without a doubt Thursday morning, August 13, at Alnes Lighthouse. The water is a bit colder than usual for this time of year, sitting at 55°, with the anomaly showing -2°, so it’s noticeably cooler than average. The conditions are glassy—zero wind from the SW—and we’ve got a 4ft swell from the WSW with a period of 8 seconds. The combined energy is moderate (312). The swell direction is WNW, which is a good match for the optimum NW direction here. It’s a point break, so that moderate groundswell should set up nicely. The crowds are only sometimes, which is a bonus. This is the clear pick for the period.
Wednesday afternoon, August 12, is a distant second option with clean but very ordinary surf—2ft from the N, short period, light offshore breeze. It’s surfable but nothing special.
After that, the window closes fast. Friday through Sunday are all poor, with cross-shore or onshore winds, small swell, and messy conditions. The energy drops off significantly. Monday and Tuesday (August 17-18) get a bit more swell but with strong cross-shore winds that will chop things up. From Wednesday, August 19, we get a few glassy mornings but the swell is too small to get excited about—2ft or less.
The second week is a bit of a drought. There’s a tiny window on Thursday morning, August 20, with a long-period 1ft groundswell from the W, but it’s too small and onshore. The following days stay small and weak, with the occasional glassy morning but nothing worth paddling out for. The last glimmer is Sunday morning, August 23, with a 3ft swell and glassy conditions, but it’s still very ordinary.
Overall, the best bet is to hit it Thursday morning, August 13. After that, you’re waiting for a long stretch of small, messy, or non-existent surf.
Rusty.

Information about the Alnes Lighthouse Surf forecast
The above surf forecast table for Alnes Lighthouse provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Alnes Lighthouse can be found by selecting the local surf guide option on the grey menu. Our Alnes Lighthouse 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 (Alnes Lighthouse) 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 Alnes Lighthouse 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.
