The Lowdown
Right then, let's have a look at what's on offer for Larmor Plage over the next couple of weeks. It's a bit of a mixed bag, to be honest, but there are a few little windows where it'll be worth getting the wettie on.
We kick off with a bit of a wait. The first proper chance to paddle out is on Wednesday the 11th of September. The morning has some hope with a 4ft swell from the west, but the cross-shore wind will make it a bit lumpy. The real highlight of this first week, and the standout for the whole outlook, is the session on Sunday the 13th of September. I'm talking about the morning. It's glassy – no wind at all – with a long-period 4ft groundswell from the west-northwest. The water is a touch warmer than normal at 67°F, and the wave energy is moderate at 314. For a beginner-friendly spot, this is about as good as it gets for a clean, cruisy session. Keep in mind it can be inconsistent and crowds are possible, so pick your peak.
The rest of the week is mostly a write-off. The 14th through the 16th are poor, with onshore winds or just junky conditions, though the 16th does see a jump in swell to 5-6ft with a moderate cross-offshore wind, meaning it’ll be clean but the wind is fresh and strong. That one is more for the experts if you don't mind the breeze.
Moving into the second week, Sunday the 22nd of September morning offers another glassy moment, but the swell is only 2ft. A nice little cruisy option for a longboard or a foamie. The next proper standout looks to be Monday the 23rd of September morning. Overnight into Monday, we get a solid 5ft swell from the west-northwest, and a light cross-offshore breeze. The wave energy is strong (533), and the conditions are clean. It's a promising call, but being over a week out, keep an eye on it – these long-range calls can change.
After that, Tuesday the 24th is small again, but with nearshore glass. The last real chance in the window looks like Thursday the 26th of September. The morning sees a 3ft groundswell from the west-northwest with a clean cross-offshore wind. It's not huge, but it'll be clean and rideable.
Overall, it's not a blockbuster 16 days. The water is a touch warmer than average for the time of year, which is nice. The standout is definitely that glassy Sunday the 13th. Get on it if you can. The rest of the time, you'll be picking through small, clean windows or dealing with lumpy, onshore slop.
Keep an eye on that Monday the 23rd. It could be the best of the second week if the forecast holds.
