The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a bit of a tease on the horizon for this spot, but we’ve got to be patient.
The next few days are pretty flat and messy. Tuesday the 1st and Wednesday the 2nd are write-offs, with small, weak swell and poor conditions. We’ll see a slight bump in energy on the 3rd and 4th, but it’s just ordinary, small stuff. Honestly, there’s not much to get excited about until we look further ahead.
The standout window is shaping up around Tuesday the 8th. That morning, we’re looking at a solid 8ft swell from the west-northwest, with a strong 13-second period. The combined energy is pumping (2035), and with a light cross-shore wind, it’s going to be a proper session at Alnes Lighthouse. The swell direction aligns well with the spot’s preference for a northwesterly. This is a bigger swell, so it’s more for the experienced crew, but the quality is there.
Then, the real gem might be Saturday the 12th. The morning is looking glassy with a clean 7ft swell from the northwest, a 10-second period, and very good surf conditions expected. The energy is solid (798), and with that glassy wind, the waves will be pristine. This is the pick of the forecast for anyone who can handle a bit of size.
There’s also a promising window on Wednesday the 9th, with a 5ft swell from the west-southwest and a gentle offshore wind. The period is 10 seconds, and the conditions are expected to be good. This is a solid secondary option, but the 12th is the one to circle.
Water temp is sitting at 58°, which is about 2° warmer than normal for this time of year, so not too bad for a September session.
Keep in mind that the second week looks a bit more chaotic, with building winds and some big, messy swell. The 12th holds the best potential, but it’s a one-day wonder before the wind ruins it.
Stay patient, and don’t sleep on the 12th.

A general guide to surfing at Alnes Lighthouse can be found by selecting the local surf guide option on the grey menu.

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.
