The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking at Alnes Lighthouse.
We’re starting off a bit slow, but there’s a bit of a pulse building. The first real chance to get wet won’t be until Saturday, the 5th of September. Saturday morning looks a bit messy with a cross-on wind, but the swell is starting to build. The real magic happens Saturday afternoon. The wind is gonna go glassy, and we’ll see a clean 5ft swell rolling in from the west with a lovely 12-second period. The combined energy is moderate (768), and it’s going to be clean. That’s your first standout.
We get a bit of a lull after that. Sunday and Monday are a write-off with strong winds and poor conditions. Tuesday the 8th of September looks promising again. The morning will have a clean, moderate offshore wind from the SSE, pushing a 5ft, 10-second west swell (532 energy). It’s not huge, but it’ll be clean. The afternoon gets a bit bigger, hitting 7ft from the west with a 12-second period (1131 energy), but the tide might be a factor.
The following week is a mixed bag, with a lot of small or windy days. The 10th of September Thursday looks tidy with glassy conditions and a 6ft short-period swell from the NW, but it’s a bit weak in energy (292-313). The water temp is sitting at 57°, which is pretty normal for this time of year.
Now, the real reason to get excited is Thursday, the 17th of September. This is the big one. The morning is glassy with a solid 8ft west swell and a 10-second period. The energy is cranking (1207). By the afternoon, it’s pushing 10ft from the west, still clean with a cross-off wind, and the energy is massive (1980). This is expert territory. It’s big, powerful, and clean. Friday the 18th of September is still good, with a 8ft to 10ft west swell, but the wind is a bit more on it in the morning, so the afternoon is your best bet.
A word of warning: that big 17th and 18th swell is a long way out, so keep an eye on the forecasts. For the average surfer, Saturday afternoon the 5th is your best bet for a clean, fun wave.
Rusty out.

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.
