The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s shaping up for Alnes Lighthouse.
First things first, the water is sitting at 55°F right now, which is about 2°F cooler than what’s typical for this time of year. Nothing crazy, just a touch on the fresh side.
The next 16 days are a real mixed bag. There’s a glimmer of hope early on, but honestly, it’s a long stretch of small, messy surf for the most part. We’ve got a big gap of days with almost nothing worth paddling out for, so don’t hold your breath.
Monday, 24 August – Afternoon: This is the one standout in the near term. The wind goes glassy, just a whisper from the WNW, and that swell starts to show some life. We’re looking at 4ft from the WNW with a period of 11 seconds, giving it a solid groundswell feel. The energy is decent, sitting at (388). It’s a point break setup, so that longer period should wrap in nicely. The wind is dead calm, making for clean, glassy conditions. This is the session to aim for if you can get out there. The crowd factor is “sometimes,” so expect a few others with the same idea, but it’s not a zoo.
Thursday, 3 September – Morning: After a long dry spell of poor conditions, we finally get a sniff of something. The wind goes light cross-off from the ENE, and the swell is small at 3ft from the W with an 8-second period. It’s surfable, but it’s very ordinary. The energy is only (139). It’s a “clean” window, but don’t expect any fireworks.
Sunday, 6 September – Morning: This one is a bit of a tease. We’ve got a 4ft, 11-second swell from the W with moderate energy (357), but the wind is a cross-shore from the NE at 15 mph. It’s not blown out, but it’s not clean either. The commentary says it’s “marginal,” so it’s a gamble.
Monday, 7 September – Afternoon: The very end of the forecast has a wildcard. The swell is tiny, only 1ft, but the period is a massive 20 seconds from the WNW. That’s a very long-period groundswell. The energy is still strong at (350) because of that period. The wind goes glassy, so it’ll be mirror-smooth. For a point break, this kind of long-period energy can be magic, but that tiny height means it’s only for the patient or those on a longboard. It’s promising, but from a week out, treat it as a hopeful guess.
Overall, the best bet by a long shot is the Monday afternoon session on the 24th of August. After that, it’s a lot of waiting and hoping for the long-range potential on the 7th of September.

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.
