The Lowdown
Alright folks, Rusty here. Let’s take a long, hard look at what we’ve got for Alnes Lighthouse over the next couple of weeks.
Right off the bat, I’ll be straight with you: the first few days are a write-off. The wind is howling from the wrong directions, mostly cross or cross-onshore, and the sea state is a messy, lumpy chop. We’re talking Monday the 10th through Wednesday the 12th – just forget it. The swell is there, but it’s ugly, and the conditions are poor. The water is a bit colder than normal for this time of year, sitting at 55°F.
Now, Thursday the 13th morning is where things get interesting. That’s the first real window. We’ve got a 4ft swell from the WSW, with a period of 7 seconds, and the wind goes completely glassy. That’s the magic word, boys. The combined energy is moderate at 333, and for a point break like Alnes Lighthouse, that glassy morning is going to be clean as a whistle. It’s the standout of the entire forecast. The swell direction isn’t the absolute optimum, but with no wind, you won’t care. It’s rideable, it’s clean, and it’s the best shot you’ve got.
Friday the 14th morning also looks promising – another glassy start with a 3ft swell from the WSW, and a longer period of 11 seconds. That groundswell energy (336) will give you some nice, lined-up waves. But the window is short; the wind picks up by afternoon, so get your session in early.
The weekend? Saturday the 15th and Sunday the 16th are back to poor conditions. Sunday morning actually sees a jump in swell height to 8ft from the WNW, but with a fresh cross-shore breeze, it’s a messy, lumpy mess. That’s expert territory if you’re desperate, but honestly, it’s not worth it.
We get another brief chance on Monday the 17th morning – glassy again, with a 4ft groundswell from the north. The energy is moderate at 223. It’s surfable, but not the quality of the previous Thursday.
The rest of the second week, from the 18th through the 25th, is a mixed bag of small, weak swells and onshore or cross-shore winds. There are a few glassy moments on the 21st, 23rd, and 24th mornings, but the swell is tiny – around 2ft to 3ft. The energy is low, under 150. You’d be on a longboard, scratching for anything. Not a lot to get excited about.
So, to wrap it up: your best bet is Thursday the 13th, first light at Alnes Lighthouse. That’s the day to make the call. Friday the 14th morning is your second option. The rest is a long, quiet stretch.
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.
