The Lowdown

Alright, Rusty here, and I’ve got the goods on Larmor Plage for the next couple of weeks. Gotta be straight with you, it’s a bit of a rough patch to start, but there’s a glimmer of something half-decent if you’re patient.

Right now, into the first week of August, it’s pretty grim. The water’s sitting at a normal 66°F, nothing unusual there for this time of year. But the swell? Tiny and weak. We’re looking at a 2ft W swell on Thursday the 6th, but it’s got a short period of 7 seconds and the combined energy is a measly 62. The wind is a messy cross-shore, so it’s just not worth paddling out. This pattern of poor conditions and small, weak swell (energy in the teens and twenties) sticks around all the way through to the 11th. It’s a real dry spell.

Now, things shift a little on Wednesday the 12th. The morning goes glassy – dead calm wind – and the swell ticks up to 2ft from the west with a 10-second period. The combined energy jumps to 98, which is still weak but way better than what we’ve seen. The wave comment says “surfable waves but very ordinary conditions,” so it’s not a standout, but it’s the first real chance to get wet. The afternoon gets choppy again, so that morning window is the one.

Thursday the 13th morning actually looks like the best of a bad bunch. We get a 3ft W swell, period at 10 seconds, and a clean, cross-offshore breeze from the ENE. The energy hits 194, which is a moderate pulse. The break is Larmor Plage, a beginner-friendly, inconsistent spot that’s fairly exposed to the SW. The swell is coming from the west, which is not its absolute optimum, but it’s close enough. The morning will be clean, but it’s not a big wave day.

After that, we slide back into a pattern of ordinary to poor conditions. A few mornings on the 14th, 15th, and 17th show clean windows with 3ft to 3ft swell, but the energy is mostly moderate (95 to 142) and the wind is cross-offshore. The 21st of August sees a morning with 3ft WNW swell, 9-second period, clean cross-off wind, and energy at 113. It’s surfable, but nothing to write home about.

Overall, the standout is Thursday the 13th morning. It’s the cleanest, most consistent window with the biggest swell of the whole run. For a beginner spot like Larmor Plage, that’s a solid call. The crowds can be an issue here sometimes, but on a Thursday morning? Might be alright. The rest of the two weeks is a grind of waiting for the wind to line up. Don’t expect any magic, but get on it if you can on the 13th.

Rusty.

Information about the Larmor Plage Surf forecast

The above surf forecast table for Larmor Plage provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Larmor Plage can be found by selecting the local surf guide option on the grey menu. Our Larmor Plage surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Larmor Plage) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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 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.
