The Lowdown
Alright folks, Rusty here, lookin’ at the charts for the Alnes Lighthouse area. Gotta be straight with you – it’s gonna be a long wait for the good stuff. We’ve got a real slow start, but there’s a proper reward if you’ve got the patience.
We’re looking at a painful drought of decent conditions for the first week and a half. From Sunday the 16th all the way through to Monday morning the 25th, it’s pretty much a write-off. Winds are all over the place, mostly cross or cross-on, and the wave quality is just flat-out poor. There’s a little bump of swell around the 5ft mark mid-week, but it’s choppy and messy each time. The water temp is sitting at 55°, which feels a bit colder than normal for this time of year.
Now, the turnaround kicks off on Tuesday the 25th. After the morning's glassy but ordinary 5ft waves, Tuesday afternoon is where we finally get a smile. We’ve got a 5ft swell from the WNW with glassy conditions. It's not the biggest, but the combined wave energy is reading a solid (293) and it’s clean. It’s a decent way to ease back into it, but the real standout isn't here.
The true pinnacle of this outlook, and the one you want to circle on your calendar, is Saturday the 29th of August. This is the day. We've got a solid 6ft to 7ft swell from the W and WSW, and get this – the period jumps to 11 to 12 seconds, a proper groundswell. The combined energy absolutely explodes, hitting a massive (1323) on the charts. The wind is offshore or light cross-off, making for some clean, punchy lines. This point break is going to be working perfectly. And on Monday the 31st, the swell actually pushes over 8ft, hitting 10ft from the WNW with glassy conditions, but at that size it’s strictly for the experts. Energy reading is through the roof at (1634). It’s a monster, but you’d better know what you’re doing.
So, the long and short of it: suffer through the first ten days, point your board at Alnes Lighthouse for the afternoon of the 25th, but don't miss the Saturday the 29th. That’s your true standout session. Monday the 31st is the big dog session for the chargers only.
Rusty, signing off.

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.
