The Lowdown
G’day, Rusty here. Look, it’s been a rough stretch of weather at Alnes Lighthouse, and the surf has taken a beating. For the first week or so, it’s pretty much a no-go with onshore winds and messy, lumpy conditions.
We’ve got a dry spell from now through September 12th. There’s some swell around, but the wind keeps killing it – all cross-shore and cross-onshore junk, leaving poor surf. The water temp is hanging around 56°F, which is right on the money for this time of year, nothing out of the ordinary.
Alright, let’s get to the only two sessions worth talking about: Sunday, September 13th and Sunday, September 20th.
First up, Sunday, September 13th is your early winner. We’ve got a 4ft swell from the WNW with an 11-second period – a nice, solid groundswell. The wind is blowing offshore from the SE at 9 mph, so the waves at Alnes Lighthouse will be clean and well-shaped. Combined wave energy sits at 423 – moderate, but it’ll have some grunt. Just be aware, this spot can get a few people on it sometimes, so get there early. The water temp is about normal.
The big highlight is Sunday, September 20th. It’s a ways off, so don’t bank on it just yet, but the signs are good. We’re looking at a 7ft swell from the WNW at 11 seconds – strong energy with a reading of 1027. Winds are light from the S at 9 mph, cross-offshore, making for clean conditions. This one will be a proper session, but 7ft is getting big for beginners. For the experienced crowd, get ready.
Before that, on Friday, September 18th and Saturday, September 19th, there’s a big pulse of swell – up to 8ft – but the winds are screaming on Friday (near gale), and even though Saturday is cleaner with cross-offshore breeze, that size is only for the pros. The 8ft on the 19th is a real beast, but it comes with rain.
After the 20th, it fades back into smaller, choppier stuff with onshore winds returning.
So, the plan: hit the 13th for a clean, fun day, and keep your eyes peeled for the 20th – that’s the one with the most potential and the biggest payoff.
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.
