The Lowdown
Alright, let’s get into it. Rusty here.
We’ve only got one spot to look at for this whole stretch: Alnes Lighthouse. It’s a point break, exposed to a fair bit of swell, and it likes it from the northwest. The water’s sitting at 56°, which is bang on average for this time of year—nothing unusual there.
The first half of the forecast is a real mixed bag, and honestly, it’s not until Saturday the 12th that things start to look interesting. Friday the 11th is a write-off: small 3-foot swell, short period, messy wind, poor conditions. You’re not missing anything.
Saturday the 12th is the one to circle. Morning has 7-foot swell from the west with a period of 10 seconds, light southerly cross-off breeze, clean conditions. The combined wave energy is moderate at 851. But the standout is Saturday afternoon: 8-foot west swell, a solid 13-second period, and a clean offshore wind from the SSE (20 km/h). The energy jumps to 2133. That’s a good, punchy groundswell, the kind that will wrap nicely into this point. It’s big and powerful—only for experienced surfers, though. This is the best on offer.
Sunday the 13th is a letdown. The swell is still big (8-foot) but the wind goes cross and picks up. It’s lumpy and messy. Not worth it.
Monday the 14th morning is back to cleaner conditions: 5-foot from the NNW, 11-second period, light southerly cross-off, clean. Energy is 799. That’s a much more manageable, fun-sized wave for intermediates. Good option if you missed the weekend.
Tuesday the 15th drops a bit to 4-foot, but the wind goes offshore in the afternoon (SE 10 km/h), so you’ll get clean little lines. Not a standout, but a solid session for a longboard or a funboard.
After that, it gets pretty grim through to the end of the third week. Swell stays small or gets blown out by strong winds. The period between Wednesday the 16th and Saturday the 19th is a real dry spell—mostly poor conditions or too messy to bother.
Then we get a big, promising blip on Sunday the 20th. Sunday morning shows a thumping 12-foot from the west with a 15-second period. That’s a very long-period groundswell. Wind is light from the SSW, cross-off, and the energy reading is 6034—that’s very strong. This is for experts only, and given the long period, it’ll be lining up beautifully on this point, but keep in mind those longer gaps between sets. Sunday afternoon bumps to 15-foot (energy 7223) and the wind goes light from the ESE, still cross-off, but it drops into “marginal” territory for tide or shape. Still, that morning window on the 20th is the other real standout of the whole forecast. It’s a week and a half out, so treat it as promising but not locked in.
The final few days from Monday the 21st onward are mostly chopped out or blown flat. A few glimpses of 8-foot on the 22nd, but with fresh winds and lumpy conditions. Not worth chasing.
Bottom line: Your best bets are Saturday the 12th afternoon and Sunday the 20th morning. The rest is either small, messy, or not for the faint of heart.
Stay salty.

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.
