Alnes Lighthouse Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming our way. We’re at Alnes Lighthouse, and the next couple of weeks are a real mixed bag. We’ve got a quiet, ordinary start, but patience is going to pay off big time if you can wait it out.

First up, this Friday, the 4th of September, is pretty flat and uninspiring. There’s just 3ft of weak swell from the North with a short 8-second period – it’s surfable but totally average, and honestly, not worth getting wet for. The water is sitting at 57°, which is about normal for the time of year. Not much happening.

Then we roll into Saturday the 5th, and that’s where things get interesting. We’ve got a 5ft swell from the West, but the real story is the period – 12 seconds – that’s proper groundswell, and the combined energy is a solid 746. But the best part? Glassy conditions in the morning. That’s a big yes from me. It’s going to be clean, lined up, and a genuine standout for the first week. The afternoon gets a bit cross-onshore and messy, so hit it early.

Sunday the 6th and Monday the 7th are written off – strong winds, lumpy cross-chop, poor conditions. Tuesday the 8th sees a clean little 3ft swell with 10-second period and glassy offshores; that’s a good sneaky session if you’re keen, but it’s not a major standout. After that, we’re looking at a long, grim stretch from Wednesday the 9th right through to Sunday the 13th. Mostly poor surf, strong cross-winds, and messy chop. There’s a gap of about 4 days where you’d be better off doing something else. That 7ft swell on the 14th is in the mix but under questionable conditions.

Now, here’s the payoff. Monday the 14th of September afternoon starts turning the corner. 6ft, clean offshores, and the guidance is saying very good. Then, hold onto your board—Tuesday the 15th of September morning rolls in with a massive 13ft swell from the Northwest (11-second period) and a combined energy reading of 3591 – that’s very strong. It’s clean, offshores, and absolutely pumping. This is the standout for the whole run. But listen, 13ft is serious size – experts only. Beginners, stay on the sand and watch the show.

Wednesday the 16th of September is a double-header. We’ve got a 10ft in the morning and then a 13ft in the afternoon, both glassy, both from the Northwest/NNW with 12-second periods. The energy is massive (2243 and 3967). That afternoon session on the 16th with 13ft and glassy conditions is a true once-in-a-forecast window. It’s clean, powerful, and the best on offer. Again, not for the faint-hearted.

By Thursday the 17th and into the weekend, the swell drops back down and the winds turn lumpy again, so the window is narrow. If you can get out on the 14th afternoon, the 15th morning, or that glassy Wednesday the 16th, you will be rewarded. The break is a point break, so that long-period groundswell is going to wrap in beautifully. It can get a crowd here sometimes, but with these conditions, it’s worth the paddle battle.

Rusty.
