The Lowdown
Right then, Rusty here again, but this time in feet and miles for the local crew. Let’s break down the Alnes Lighthouse stretch.
We’ve got a point break here that needs a good northwest swell and a southeast offshore breeze. The water’s a cold 55°, which is a touch chillier than the average for August.
This first week is a write-off for the most part. Starting Thursday the 20th, we’ve got small, messy waves and the wind is all over the place. The only semi-interesting moment this week is Saturday afternoon the 22nd: tiny 2ft waves from the north, glassy conditions, but the energy is weak at 90. Just a splash-around.
The one true bright spot in this forecast is Wednesday morning, August 26th. We get an east-northeast cross-offshore breeze, which is perfect for Alnes Lighthouse. The swell is a clean 3ft out of the north-northwest with a 10-second period, giving a combined energy of 296. That longer period will wrap into the point nicely, and the light offshore wind will leave the face smooth. It’s a bit inconsistent, but since crowds are only "sometimes", you could have a fun, quiet session.
Further out, Thursday morning, September 3rd also shapes up nicely. Light cross-offshore wind from the east-southeast again, with a bit more size at 5ft out of the north-northwest. The period is lower at 8 seconds, but the energy is solid at 326. That’s two weeks away, so don’t book the day off yet, but it’s worth a marker on the calendar.
Between those days, expect a lot of nothing. Especially from the 28th of August through the start of September, we have near-gale winds and tiny waves – a few days best spent working on the van. The 4th of September shows a 8ft swell, but with a strong cross-shore wind and chop, it’s an expert-only session if it cleans up.
So, for the pick of the bunch: Wednesday the 26th for some clean, easy waves, and keep an eye on Thursday the 3rd for a bigger, cleaner swell. The rest is a borderline lost cause.
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.
