The Lowdown
Alright folks, Rusty here. It’s been a bit of a flat spell at Larmor Plage, and honestly, for the next week, it’s a waiting game. The first few days are a write-off with messy wind and weak, choppy lines. The wind is just all over the place, and the swell is struggling to get its act together. We’re looking at a serious gap in any real quality surf until around the 20th of August.
However, there’s a glimmer. Thursday morning the 20th of August is the first time we see something worth getting out of bed for. The wind will be offshore, a gentle breeze from the north cleaning up a 3.9ft W/NW groundswell. The energy is moderate (250) and the period is a solid 10 seconds, giving the waves some real shape. The break is fairly exposed to the west, so it’ll catch that energy fine. Water temp is about average for the time of year here. Don’t expect a crowd-free zone, as it can get busy, but for a Thursday morning, you might find a few.
The real standout, and the one I’m circling on the calendar, is Thursday morning the 27th of August. The models are throwing up a solid 4.9ft swell from the west-northwest, with a 9-second period and a moderate 397 in energy. The wind is a light, offshore breeze, making it clean. This is expert territory at that size, but for the crew who know what they’re doing, this is the best wave of the outlook. The long-range promise is there, but it’s a ways out, so keep your fingers crossed.
Before that, there are a few sessions that are just "surfable". Friday morning the 14th of August has a clean 2.6ft runner with offshore wind, but it’s just very ordinary. Saturday morning the 15th of August is the same story with a clean 3.0ft. They’re okay for a beginner to get wet, but nothing to write home about. The 20th of August is the first real ticket, and the 27th is the big one.

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.
