The Lowdown
Alright folks, Rusty here. Let’s get into it for Larmor Plage. To be straight with you, the wait for something decent is going to feel long. The first week is pretty much a write-off. We’ve got a handful of mornings where the conditions are clean, but the swell is just too small to get excited about – we’re talking 1ft to 2ft with weak energy (19 to 43). The wind is often light and cross or cross-off, but the waves have no push. Afternoons get messy with a stronger onshore or cross-shore breeze and a chop. This pattern holds through to the weekend of the 10th and 11th.
By the 12th of August, Wednesday morning, we start to see a little life. The swell picks up to 2ft from the west with a 10-second period, and the energy climbs to 98. The wind is a light cross-off from the WNW, which will keep the surface clean. It’s rideable, but still on the small side. The Thursday morning, the 13th, is similar with 3ft, a 9-second period, and a light offshore from the NNE – that’s a clean window. The energy is moderate (144). The 14th and 15th mornings are also clean, but the swell stays small.
Now, for the real standout. If you’ve got patience, mark your calendar for the morning of Tuesday, August 18th. This is the one. The swell pushes up to 7ft from the WNW with a 9-second period, and the combined energy is a massive 1082 – that’s strong. The wind is a light offshore from the ENE, which will make for glassy conditions. This is proper, powerful surf. At 7ft, it’s going to be a bit much for beginners, but for anyone with experience, this is the best session in the whole outlook. The wave quality is rated as very good.
The afternoon of the 18th gets messy again with a cross-shore wind, but the morning session is the clear winner. After that, the 20th and 21st of August have some clean mornings, but the swell drops back to 3ft, so it’s back to smaller, more ordinary conditions.
Water temp is about average for the time of year, so no surprises there.
Rusty.

A general guide to surfing at Larmor Plage can be found by selecting the local surf guide option on the grey menu.

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.
