The Lowdown
Alright, folks, Rusty here again. Let’s get straight to it. We’ve got a pretty messy stretch of ocean ahead, but there are a couple of windows where it’ll clean right up. I’m looking at Alnes Lighthouse, and the long-range picture is all over the shop, so let’s break it down day by day.
The first few days are pretty ordinary. We’ve got swell, but it’s messy and the wind is all over the place. Wednesday the 17th has a bit of a pulse, but it's short-period and not doing much. You’ll see some cross-off conditions early Thursday with a bit of size, but the wind is going to be a factor. It’s a case of checking the banks, not a day to be picky.
The real highlight, and the standout of this whole period, is looking like Thursday the 24th. That’s when we finally see conditions come together. We've got a good W-WNW swell pushing 6.5ft with a 12-second period, and the wind is light offshore. The water temp is sitting in the mid-50s which is, you know, pretty normal for this time of year. The whole place is going to have some proper shape to it. I’d be calling this the pick of the month, hands down.
The following week is a mixed bag. On Friday the 25th, the swell is going to blow up, with waves in the 16ft range on the face, but it’s coming with a nasty cross-shore wind. Saturday the 26th starts big too, but again the wind is howling, so the surface is going to be a mess. After that, the whole thing fades out into the end of the month with a lot of onshore and cross-shore junk, and you’ll see the swell dropping off as we head into early October. The first few days of October look pretty flat and soft. There’s a bit of a blip on the 1st with some clean, small waves, but it’s not worth getting excited about.
It’s a tricky run of it, but that Thursday the 24th is your day. Otherwise, it’s about finding a bit of shelter from the wind. Be patient, and don’t force it on the big, blustery days. That’s it from me.

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.
