The Lowdown
Alright, folks, let's get into it. We're looking at the Alnes Lighthouse (Alnes-Lighthouse) point break. Water temperature is sitting at 58°F, which is a touch warmer than normal for this time of year, so the wetsuit might feel a bit more comfortable than usual.
The next couple of days are a write-off. Monday and Tuesday are a total loss with poor surf – small, weak waves and mostly cross or onshore wind. The combined swell energy is pathetic, barely cracking 50-88 (weak energy). There's a real gap here with nothing to ride until Wednesday afternoon.
Wednesday the 2nd of September sees a pulse of energy arrive, but it's a tricky one. The morning swell jumps to 6ft from the WSW with a short 8-second period, and the wind is a strong cross-off. The combined energy hits 517 (moderate energy), but it's still a messy, low-quality setup. The afternoon gets bigger, up to 10ft, but that's a lot of water for a point break – definitely for experienced surfers only, and the wind is still howling. It's a pass.
Thursday morning the 3rd is the first decent window. The swell drops to a clean 5ft from the WSW with a gentle cross-off breeze. The combined energy is 282 (moderate). It's a solid, clean wave, but not a standout. The afternoon goes to crap again with onshore wind.
Then we get a bit of a lull. Friday and Saturday morning are small and clean, but the energy is weak. The real standout is shaping up for Saturday the 5th of September. The morning brings a glassy 5ft swell from the west with a long 13-second period. The combined energy is a solid 960 (strong wave energy). This is a groundswell with some real push, and the sets will have nice gaps. The wind is glassy, so the point break will be clean and lined up. This is the best session of the first week. The afternoon gets a bit of onshore wind, so get out early.
Sunday the 6th is okay but not special. Monday the 7th is blown out again with 45 km/h winds. The whole first week of September is a bit of a mixed bag.
Now, looking further out, things get interesting. Wednesday the 9th of September morning is glassy with a 6ft swell from the NW and a combined energy of 1179 (strong). That's a solid groundswell. The wind is dead calm. This is a strong option.
But the real standout for the whole 16-day window is Thursday the 10th of September. Thursday morning is looking excellent. We've got an 8ft swell from the NW with a long 13-second period. The combined energy is a massive 2241 (very strong). The wind is a light offshore from the east, so the point break will be firing with clean, lined-up sets. This is a big, powerful groundswell at a point break – a classic setup. This is for experienced surfers only, as 8ft is a serious size. The afternoon gets a messy cross-shore, so hit it early.
Friday the 11th is too big and messy, with 12ft swells and howling NE winds. That's what you call a kite-surfing day, not a paddle-surfing day. The following weekend (12th-13th) drops back in size, but the wind is mediocre.
Way out on Tuesday the 15th of September, we get a glassy morning with a 4ft west swell sporting a long 14-second period. Combined energy of 638 (moderate). It's a long-range, promising call, but less certain. The afternoon is glassy too. A nice way to cap off the forecast.
So, to wrap it up: the first few days are a total blank. The best window is the morning of Saturday the 5th of September for a clean, medium-sized groundswell, and the absolute standout is the morning of Thursday the 10th of September for a big, powerful, clean NW groundswell at the point. That's the one to circle.

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.
