The Lowdown
Alright folks, Rusty here. Let's have a look at what Larmor Plage has in store for us over the next couple of weeks.
The overall picture is a bit of a mixed bag, to be honest. There's some swell on offer, but the wind is often working against us, making a lot of the sessions look pretty ordinary. The water temp is sitting at 66°F, which is about normal for this time of year, so no surprises there.
Tuesday 1st September kicks things off with a glassy morning. The swell is 4ft from the west, with a period of 9 seconds, and the combined energy is 246 (moderate). It's surfable, but conditions are described as very ordinary. By the afternoon, the wind picks up and messes it up.
Wednesday 2nd and Thursday 3rd are a write-off. The swell gets small and the wind is onshore or cross-shore, creating chop. Nothing to get excited about.
Friday 4th September morning offers a little hope. The swell is 3ft from the WNW (9 seconds, 123 energy), and the wind is light and cross-offshore, making for clean conditions. It's still labeled as "very ordinary," but it's a session, not a total loss.
Saturday 5th September morning is similar, with a 3ft west swell (9 seconds, 176 energy) and clean, cross-offshore winds. Again, it's not a standout, but you could get a few.
The next few days are mostly poor, with onshore winds and a messy surf.
Now, here's where it gets interesting. Monday 7th September morning is an absolute gem. The wind is dead calm, glassy, with a 4ft west swell and a period of 12 seconds. The combined energy bumps up to 352 (moderate). Expect good surf conditions. This is the best session of the entire forecast, a real stand-out for the clean, lined-up waves.
The afternoon of the 7th sees a bigger 6ft WNW swell (11 seconds, 778 energy), but the wind is a moderate cross-shore, making it marginal and messy. That size is getting into the "not for beginners" territory.
Tuesday 8th morning is clean again with a 3ft west swell, but it's back to "very ordinary."
A long gap of poor or ordinary conditions follows until Monday 14th September. That morning looks promising again. A 4ft west swell with a 12-second period (391 energy) and a light cross-offshore breeze from the east. The forecast says "expect good surf conditions." This is another one to circle on the calendar, but it's a long way off, so keep an eye on it.
Finally, Wednesday 16th September afternoon has a weird one. The swell is only 2ft from the west, but the period is a massive 17 seconds (423 energy), and the wind is offshore from the NNW. Conditions are clean. That long period will make for some very clean, long lines, but it's a small swell, so it might be a bit inconsistent.
To sum it up, the standout sessions are the glassy morning of Monday 7th September and the promising morning of Monday 14th September. For the rest, it's a lot of waiting and hoping the wind plays ball.
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.
