The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks at Larmor Plage. To be honest, the first week is a bit of a write-off for a proper surf. We’ve got a real bumpy start with messy, cross-shore winds and lumpy conditions that just aren’t worth paddling out for. The wait looks like it’ll be worth it if you’re patient, 'cause the second half of the forecast has some serious muscle rolling in.

The first real chance to get wet comes on Friday morning, 21st August. The swell is a clean 4ft from the WNW with a period of 10 seconds, and the wind is a light cross-offshore breeze. The water is sitting at 68°F which is about 2°F warmer than usual for this time of year, so it’s a touch on the warm side. The combined energy is moderate at 322, and while it’s not a massive day, the conditions will be clean and surfable. It’s your best bet for a proper session early on, but be aware this spot is inconsistent, so you’ve got to be on it when it’s working.

The rest of that week and into the next is a real struggle. We get a drop in swell size with tiny, waist-high dribble and winds that are either onshore or too strong. Saturday morning the 22nd has a small 2ft with a gentle offshore wind, making it clean, but the energy is a paltry 89 – it’s a beginner’s splash-around or a good day for a log.

Then we hit a big gap. From Sunday the 23rd right through to Tuesday the 26th, the swell is tiny, under 2ft, and there’s just no power. It’s a proper flat spell.

Things get interesting again on Wednesday morning, 26th August, but not in a good way for surfers. We get a strong 5ft SSW swell, but the wind is a howling 25 mph onshore. The combined energy jumps to 584. This is a kite surfer’s paradise, not a paddle surfer’s. The same goes for the 10ft swell on Thursday the 27th – that’s heavy, expert-only territory, and the wind is messy.

The real standout, and the one to circle on your calendar, is Monday morning, 31st August. The surf is a solid 10ft from the west with a very long period of 13 seconds. That’s proper groundswell energy. The combined energy is a massive 2519, which is incredibly powerful. The wind is a clean cross-offshore breeze, so the conditions will be clean. But listen, at 10ft, this is for experienced surfers only. It’s too big for beginners. Also, with that long period, it’s going to be a bit straight and fast on the beach, so look for a point or reef if you can. The afternoon gets even bigger at 12ft, but the wind turns cross-shore and lumpy, so the morning is the window.

The following Tuesday, 1st September, is still solid with 8ft from the west, but the wind is messing it up. After that, it seems to drop off and get wind-affected again.

So, for the best of the bunch, I’m calling Friday morning, 21st August for a clean, fun size session, and Monday morning, 31st August for the big, powerful groundswell if you’ve got the skill and the nerve. The rest of the time, it’s either flat, bumpy, or blown out.

Stay stoked,
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.
