The Lowdown
Alright, let's take a look at what's coming our way for the Larmor Plage area. Honestly, it's a bit of a tough stretch ahead. The next couple of weeks are looking pretty bleak for a decent paddle, so don't get your hopes up.
We start off with a real quiet spell. The first couple of days have some swell, but the wind is all wrong. It's not until Monday the 7th that we see a bump in size, with a 5ft to 6ft West swell rolling in, but the wind is cross or cross-shore, making it messy. The wave energy is moderate, hitting about 984 and then 955. But the forecast is calling it marginal, so it's not something to get excited about. Then the following days are a write-off. Tuesday the 8th gets smashed by a strong 25 mph cross-onshore wind, making it a total mess. The rest of the first week and the start of the second are a real letdown, with tiny waves and onshore or cross winds.
There is a tiny glimmer of hope on Monday the 21st. The afternoon shows an 8ft West swell with an 11-second period, and the wave energy jumps up to a strong 1465. The wind is a gentle cross-shore, which is okay, but the height is getting into expert-only territory. The problem is, the forecast still rates it as marginal, so it's a bit of a gamble. The water temp is around 66°F, which is about average for this time of year, nothing wild.
But honestly, for the whole 16-day run, there’s nothing that screams "go session." It’s mostly poor conditions, onshore winds, and inconsistent, small swells. For a break like Larmor Plage that’s a fairly exposed beach break, the setup with that strong wind and messy conditions looks more interesting for kite surfing than for a traditional paddle session. It’s a real bummer.

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

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.
