Alnes Lighthouse Surf Forecast and Surf Report

Alright, let’s talk about Alnes Lighthouse. This is a point break, exposed to the north-west swell, and what we’ve got over the next 16 days is a real mix—some flat spells, some wind-blown garbage, and a couple of windows that’ll make you want to clear your schedule.

Right out of the gate, Thursday September 3rd is a dud. Cross-shore winds and weak, short-period swell mean the ocean’s ugly. Friday morning the 4th is glassy dead calm, but the swell is tiny—just 2 feet from the NNE. You might find a knee-high lump, but that’s about it.

Then Saturday September 5th shows some life. The morning brings a 5 foot west swell with a solid 13-second period—that’s real groundswell energy. The combined energy is 941, moderate but solid. The wind is a light cross-shore, so it’s a bit textured but rideable. That long period should bend nicely around this point. It’s not perfect, but it’s the first real option. Crowds are possible here.

Sunday the 6th and Monday the 7th are messy or hammered by wind. Monday afternoon has a 45 km/h cross-shore that ruins everything.

The first real standout is Tuesday morning, September 8th. We’ve got an 8 foot swell from the west with a 10-second period, and the energy is pumping at 1420—strong power. The wind is offshore from the southeast at 20 km/h, so the waves will be clean and lined up. This is a great session for experienced surfers. It’s too big for beginners, but for anyone comfortable in solid surf at this point, get out there early. The afternoon gets sloppy with a cross-shore and the swell hitting 10 feet, so morning is the move.

The next few days are weak or windy. There’s a tiny, glassy moment on Friday afternoon the 11th, but the swell is only 2 feet. Not worth it.

A big gap of average days leads to Sunday, September 13th. By the afternoon, the swell jumps to 12 feet from the west with a 12-second period, and the energy is massive at 3546. The wind is a light cross-onshore, so it’s not glassy, but the power is immense. Experts only. That kind of long-period west swell on this point will produce big walls, just with a little chop.

The biggest standout is Wednesday, September 16th. The morning brings a huge 13 foot swell from the WNW with a very long 14-second period—that’s deep ocean groundswell. The combined energy is a monster 6709. The wind is a light cross-off, keeping the waves clean. The afternoon is still massive at 12 feet and 13 seconds, with energy at 4441 and clean conditions. This is serious, heavy water—only for the best. If you’ve got the skill and the nerve, this could be the session of the year.

Water temp is about 57°F, which is pretty average for this time of year.

So, the two best bets: Tuesday morning, September 8th for a clean, solid 8 foot swell with offshore wind, and Wednesday, September 16th for the sheer size and power of that 13 foot WNW swell with clean conditions—that one’s for the experienced crew only.
