The Lowdown
Alright folks, this is Rusty with your local surf outlook for the Alnes Lighthouse area. Let's get into it.
The coming fortnight is a bit of a mixed bag, with one decent window early on and then a long, quiet stretch. We’ve got some swell energy to work with right at the start, but the quality is going to be the main challenge.
The first few days are where the action is. Thursday morning, August 13th, we’ll see a 4ft WSW swell pumping in at 11 seconds, carrying a moderate 478 units of energy. The water is sitting at 55°, which is a bit colder than usual for this time of year, so don't forget the extra rubber. The problem is the wind is a light cross-shore, which will leave the surface a little bumpy. It’s not a total write-off, but it’s not the cleanest either.
Friday morning, August 14th, looks much better. The swell drops a touch to 3ft from the WSW, still with a solid 11-second period, and the energy is a solid 309. The key here is the wind shifts to a light cross-offshore breeze, delivering clean conditions. This is your best bet for the entire outlook. The Alnes Lighthouse point break should be offering up some fun, lined-up waves. Late Friday afternoon goes glassy with the wind dropping to zero, but the swell is fading to 3ft.
From Saturday, August 15th, things take a turn. The wind ramps up and the conditions get messy with a lumpy cross-chop as the swell hangs around the 3ft mark with weak energy. By the time we get to Sunday, August 16th, a new 6ft NW swell is on the cards, but it’s a short 8-second period and the wind is howling, creating a right mess. This one is a miss.
Then comes the long drought. From Monday, August 17th, right through to the end of the forecast on August 28th, the surf is mostly poor. The swell drops significantly, the wind is all over the place, and the energy values are low, often under 200. There are a few moments of glassy or clean conditions right at the very end on the 27th and 28th of August, but the swell is tiny, around 2ft to 3ft, with hardly any energy (18 to 85). It’s a long stretch of small, poor-quality surf, so don't get your hopes up for that second week.
So, the standout is clear: Friday morning, August 14th. That 3ft WSW swell with the light cross-offshore wind will be the cleanest and most fun you’ll see. The rest of the period is a grind.
This is Rusty, signing off.

A general guide to surfing at Alnes Lighthouse can be found by selecting the local surf guide option on the grey menu.

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.
