The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up.
Honestly, the next week and a half is a struggle. For Alnes Lighthouse, we’re looking at a long drought of poor surf conditions from now all the way through early September. There’s nothing worth paddling out for until Tuesday morning, the 1st of September, and even that is just “surfable waves but very ordinary conditions” with a tiny 3ft swell from the NNW at 8 seconds – weak energy (83). The wind is glassy that morning, which is nice, but the swell is just too small and weak to get excited about.
Then it gets messy. The 2nd of September brings a big spike in energy (461) but with howling 25 mph cross-onshore winds and rain – that’s not surf, that’s a washing machine. The water is 57°F here, which is about average for this time of year, so no surprises on that front.
The first real standout doesn’t show up until Friday morning, the 4th of September. That morning looks promising: 4ft swell from the WSW with a 10-second period, light glassy wind from the WNW, and moderate wave energy (361). The swell direction is a bit off the optimum NW, but the clean glassy conditions will make it surfable and fun for intermediates. The combined energy is solid enough to get some proper rides.
Then on Saturday the 5th of September, the afternoon session is the true highlight of the whole outlook. We’ve got a solid 6ft groundswell from the west at 12 seconds, light glassy easterly wind, and strong wave energy (1092). That’s a real groundswell, long period, so it’ll peel nicely at this point break. The size is right for experienced intermediates – too big for beginners, but not stupid. Crowds are possible here, so get there early.
After that, the energy drops off again. Sunday the 6th has a glassy morning with 4ft and good conditions, but the rest of the second week fades into small, weak, or windy setups. There’s a rough spell on the 11th and 12th with big 7ft+ swell but howling near-gale winds – that’s kite territory, not paddle surfing.
Bottom line: hold out for the 4th and 5th of September. Friday morning and Saturday afternoon are your best bets. The rest is a write-off or just not worth the effort.
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.
