The Lowdown
Alright folks, let’s get into it. Rusty here.
Right off the bat, I gotta be straight with you. The first few days through the end of August are looking pretty grim. The short period swell is weak, the wind is messy, and the models are just not giving us anything clean. We’re looking at a real dry spell until we get to the start of September. There’s a 7 to 8-day gap with no real surf on offer, which is a bummer for a stretch that usually has a bit more pulse.
The first real glimmer of hope comes on the morning of Monday, 1st of September. The onshore junk has finally backed off, and Larmor Plage wakes up to glassy conditions. The wind is light and variable from the SW, practically a dead calm (3 mph). The swell is a clean 5 ft from the west, and it’s got that lovely 10-second period that means real groundswell energy. The combined energy is moderate (386). The water is 65°F, which is about average for the time of year. This is beginner-friendly in size, and with the offshore wind, it’ll be the cleanest we’ve seen all week. The only catch is it’s inconsistent here, so you’ll be waiting for the sets, but when they come, they’ll be proper.
Then we get a bit of a lull again for a few days. The wind picks up, the swell drops, and it’s back to cross-shore chop. That’s the pattern.
Now, if you’ve got the patience and the skills, the real standout is lurking way out there on Monday, 7th of September. This is the one. The models are lining up a solid 12 ft west swell with a 17-second period. That’s very long-period groundswell, serious energy. The combined energy is a massive 9857, which is strong. The wind is a moderate cross-shore from the WSW, which is manageable. For a beach break like Larmor Plage, that long period can make it break a bit straight and be a handful, but for the expert crew, this is a big, powerful day. The caveat is the size: over 8 ft, this is strictly for experts. Beginners will be in over their heads. It’s a week away, so don’t bank on it, but it’s the only one that earns a real standout nod for the whole 16-day window.
The morning after, on Tuesday, 8th of September, the swell is still solid at 7 ft from the west, with a 14-second period, and the wind goes cross-offshore from the WNW. That’ll clean it up nicely (1433 combined energy). It’s a step down in size, but still a powerful day for experienced surfers.
So, to sum it up: a long wait, a clean glassy session on the 1st for the beginners and intermediates, and a massive, expert-only day on the 7th. The rest is just wind and chop.
Rusty.

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 Larmor Plage 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.
