The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the Alnes Lighthouse area.
We’ve got a bit of a slow start, but the forecast is building towards a cracking finish. The first few days are a write-off for surfing, with a lumpy cross-shore breeze and messy conditions. From Saturday the 5th right through to Monday the 7th, it's a no-go. Tuesday the 8th, however, is where things get interesting.
Tuesday morning, September 8th, is the first real standout. Alnes Lighthouse is waking up to a clean 7ft swell from the west with a long 14-second period, which is proper groundswell energy. The wind is light offshore from the southeast, so the faces will be clean. The combined energy is pumping at 1822, so there's plenty of power in the water. This is a solid intermediate wave, but at 7ft, it's getting into the territory where beginners might want to sit this one out. The water is sitting at 56°, which is just about average for this time of year, nothing unusual.
The next big window doesn't come until much later. We have a bit of a lull with small, weak swells and messy winds for over a week. There's a tiny window on Tuesday morning, September 15th, with a glassy 3ft swell from the west-northwest, but it's not the main event.
The real gems are waiting for us in the second week. Thursday, September 17th, is looking epic. The morning sees a 13ft clean west-southwest swell with a cross-offshore breeze, and the energy is massive at 2640. Then, the afternoon is the absolute highlight: a 15ft west swell with a 12-second period, glassy conditions, and a combined energy of 5059. That is a huge, powerful, clean swell, but make no mistake—this is expert territory only. This is a point break, so it should handle that size, but you need to know what you're doing.
Friday morning, September 18th, is also a cracker, with a 10ft clean swell from the northwest and an offshore breeze. Energy is still very strong at 1856. The afternoon drops off a bit, but it's still a very good session.
This spot is fairly exposed to the swell, but it's a point break, so it handles the long-period groundswell well. It can get crowded sometimes, so be prepared to share the peak. The standout here is undoubtedly Thursday the 17th afternoon, with that glassy, giant west swell.
Rusty, signing off.

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.
