The Lowdown
Right then, let’s have a proper look at what’s coming our way for the next couple of weeks.
Honestly, it’s a bit of a mixed bag to start. We’re looking at a long stretch of pretty average conditions, and it’s not until around Friday the 15th of August that we finally see a bit of life in the water. The first proper session to pencil in is that Saturday morning, the 15th of August. The water temp’s sitting at 67°, which is a touch warmer than usual for this time of year by 1°, so nothing too unusual there.
Right, for the standout, you’ve got to look at Saturday morning, the 15th of August. Larmor Plage has a clean 4ft swell rolling in from the WNW. That period is a short 8 seconds, so it’s a bit of a windswell, but the energy’s moderate (289). The wind is a light offshore from the NNW at 9 mph, making for clean, lined-up waves. It’s a beginner-friendly spot, but it is inconsistent and can get busy sometimes. That window on Saturday morning is definitely the pick of the first week.
After that, things fade right off. Sunday the 16th drops down to 3ft with clean conditions but almost no energy, and then from Monday the 17th right through to Friday the 21st of August, it’s mostly tiny or flat, with a lot of poor surf conditions. There’s a bit of a spike on Thursday the 20th of August afternoon, with a 5ft swell from the WNW and good energy (370), but the wind is a cross-offshore at 12 mph, so it’s not as clean as it could be. It’s flagged as marginal, so keep an eye on it.
Then there’s another little bump on Saturday the 23rd of August – no, actually that’s poor. The next flicker is on Monday the 24th of August afternoon, with a glassy 2ft from the WNW, but again, nearly no energy behind it.
As we push into the second week, the outlook gets even less certain. Wednesday the 26th of August morning has a 4ft swell from the WNW with moderate energy (249), but the wind is cross-off at 12 mph. Thursday the 27th of August morning has a 3ft swell from the W with a decent 10-second period and clean conditions, but it’s just ordinary.
So, to call it straight: Saturday morning, the 15th of August is your best chance for a fun, clean session on a small but workable wave. The rest of the window is largely a write-off for decent paddle surfing.
Stay patient, lads. It’ll turn around.

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.
