The Lowdown
Right then, let’s talk in feet and Fahrenheit.
We’re starting slow at Alnes Lighthouse. Wednesday and Thursday (the 3rd) are mostly a no-go. Wednesday morning had about 7ft from the WSW, but the wind was messy cross-off and the conditions were "marginal". Water temp is about 58°, which is slightly warmer than average for now.
Thursday the 3rd drops to small, weak waves under 3ft with poor conditions. Friday the 4th is similar—small, clean but nothing special. The wave energy is weak, down around 96.
Saturday the 5th wakes things up. Morning brings a clean 5ft swell from the West with a 12-second period—proper groundswell. Light cross-off winds, clean face. Combined energy is a solid 867 (moderate). This is the first real standout for intermediates. Crowds might pop up, so expect some company.
Sunday and Monday (6th-7th) are messy cross-shore affairs, no quality.
Then we hit Wednesday, September 9th. Morning is glassy, no wind, with a 8ft swell from the West and 12-second period. That’s expert territory—over 8ft is for the experienced only. Combined energy is 1665 (strong). The wave is clean, powerful, and a true standout. By afternoon, the wind swings onshore and ruins it.
After that, Thursday the 10th through the weekend drop to smaller, weaker surf. The second week is mostly small or windy days, though there’s a pulse on Wednesday the 16th with 10ft in the afternoon and Thursday the 17th with 7ft and clean cross-off winds. But those are far out and less certain.
Your best calls: Saturday morning the 5th for all-round fun, and Wednesday morning the 9th for the big, clean grunt. Everything else is mostly waiting for the next pulse.

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.
