The Lowdown
Alright, surfers, Rusty here. Let's have a proper look at what's on the table for this stretch.
It’s been a bit grim to start, and honestly, for the next week or so, you might as well take a break. The first real chance to get wet doesn't show up until the morning of Saturday, 7th August, but even that’s nothing to write home about. We’re looking at a flat, weak run until then.
The first sniff of something surfable is on Saturday morning at Alnes Lighthouse, with a 4ft swell from the WSW. It’s small, but the cross-off breeze will keep it tidy. That afternoon the swell bumps up to 5ft, still clean, but it's a short period windswell. It'll be okay for a longboard, but not much grunt behind it. The wave energy is moderate at best.
Sunday morning gets a bit punchier with a 7ft W swell, but the wind swings cross and it gets messy. The afternoon cleans up again with a 6ft swell and a light cross-off, but conditions are marginal. We then hit a long, flat stretch of poor surf with onshore winds all the way through until the middle of the following week. There’s a brief glimmer on Wednesday afternoon, 12th August, with 4ft of N swell and glassy conditions early, but the period is still short. It’s not worth getting excited about.
Now, if you’re patient, there is one standout that could be worth the wait. Mark your calendar for Thursday morning, 20th August. Alnes Lighthouse looks to fire with a solid 8ft groundswell from the WSW, a very long period of 15 seconds, and glassy conditions. That’s a recipe for powerful, clean waves, though at that size it’s strictly for the experienced crew. The combined swell energy is very strong. This is a classic point break setup, so expect those long-period lines to wrap in beautifully. The water temp is about average for this time of year.
The following days look like they’ll get blown out again by strong cross-shore winds, so that Thursday window is your best bet. It’s a long way out, so keep an eye on the charts, but it’s got the makings of a proper session.
Stay safe out there.
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.
