Larmor Plage Surf Forecast and Surf Report

G’day, Rusty here. Look, I’m gonna level with you—this stretch of water at Larmor Plage is looking pretty quiet for the next few days. There’s a run of marginal to poor surf from now until the end of the first week, so don’t bother paddling out until we get a proper window. The water’s sitting at 66°, which is about average for this time of year, so nothing weird there.

We finally get a proper standout on Monday, September 7th. Monday morning at Larmor Plage is the one to point your board at. Swell’s a solid 5 ft from the west, with a long period of 13 seconds—that’s proper groundswell energy, and the combined energy reading is 797 (moderate to strong). The wind’s coming from the west-northwest at 9 mph, which is a cross-offshore breeze, and the wave comment says “clean.” This is the best on offer by a long shot. The swell’s big enough to be fun for intermediate surfers, but at 5 ft it’s not too heavy for most. That long period means the waves will have good shape and power, but at a beach break like this, it might make them a bit straight—still, the clean conditions make it worth it. Crowds are only “sometimes” here, so you might get a few out, but nothing crazy.

The afternoon of the same day gets messy—wind swings to 16 mph onshore and the quality drops off. Tuesday the 8th has a 6 ft swell from the west with 10-second period, but the wind’s a cross-shore 9 mph and the conditions are only marginal, so don’t expect much.

Later in the week, Wednesday the 9th morning has an offshore breeze from the north at 6 mph and a 4 ft west-northwest swell, but the period is only 8 seconds and the energy is weak (207). It’s clean, but nothing special.

The second week is a bit of a mixed bag. There’s a promising window on Tuesday the 15th and Wednesday the 16th. Tuesday afternoon has a 4 ft swell from the west with a very long 16-second period, clean cross-offshore wind from the northeast at 12 mph, and strong energy (773). That’s a standout for the second week—long-period groundswell, clean faces. Wednesday morning the 16th brings a 5 ft west swell, 14-second period, and a light cross-offshore from the east-northeast at 9 mph, with energy at 791. Both are solid but the long period might make the beach break a bit tricky. Still, these are the best of the back half.

Thursday the 17th morning has a tiny 2 ft swell with glassy conditions—dead calm from the north-northwest at 3 mph. It’s clean but small, and the energy is weak (133). Not a day to get excited about.

Overall, the standout is Monday morning the 7th—5 ft west swell, 13-second period, cross-offshore wind, clean. For the second week, target Tuesday afternoon the 15th or Wednesday morning the 16th for that long-period groundswell. The rest is mostly flat or messy. Stay patient.

Rusty.
