The Lowdown
Alright, surfers, Rusty here. Let’s talk about what’s happening at Larmor Plage. This is a tough outlook right now; the next week looks pretty grim. There’s some decent swell building later on, but you’re going to have to be patient.
The water temperature is sitting at 65°, which is pretty much exactly what you’d expect for this time of year.
The forecast starts on Wednesday, August 26th, with barely a ripple. That tiny 1ft of WNW swell is a no-go. It’s small, weak, and the wind is a mess. This continues through the rest of the week. We get a bump in size on the 27th to 4ft, but it’s short-period stuff (7 seconds) from the SW with onshore wind. It’s just lumpy, messy, and not worth bothering with.
Friday afternoon the 28th sees a jump to 6ft, but again, it’s blown out. The energy jumps up to 541, showing there’s some power, but the wind is on it and it’s a poor setup. Saturday the 29th gets even bigger, with 7ft to 8ft of swell, but with a fresh onshore wind of 22 mph, that’s just a washing machine. Even Sunday the 30th has a 5ft swell from the west with a period of 10 seconds (moderate energy of 646), but the wind is cross-onshore and messy. It’s a write-off.
Finally, Monday morning August 31st, we get a little window. The swell is solid at 7ft from the west, period 9 seconds, and the wind goes light offshore from the WNW. The energy is a solid 788, but it is only a marginal call. For experienced surfers, that morning might offer some bowls, but the afternoon turns to crap again. September 1st is back to small, weak, and cross-shore wind.
There’s a glimmer on Thursday morning, September 3rd. The swell is tiny, only 3ft, but the wind is glassy from the ESE. That would be a morning for a foamie or a log, just to get wet. But the energy is only 108, so don't expect much push.
The standout finally comes around on the 5th and 6th of September. It’s not huge, with a consistent 3ft of swell from the west, but the wind is the story here. On Saturday morning, September 5th, we get a moderate offshore breeze from the NNE. That will clean the waves right up. It’s surfable, ordinary, but it’s the best we’ve seen all week. The 6th is similar, with light cross-offshore conditions.
Looking further out, the 7th of September brings a bigger pulse of 6ft-7ft from the west. The energy is a massive 1726 by the afternoon, which is a lot of power. The wind is light onshore, so it won’t be perfect, but that is a lot of water moving. Tuesday morning the 8th of September is the clear winner. You’ve got a clean 5ft of west swell with a light offshore wind from the north. The energy is 320. That is a promising window for a proper session. After that, it fades out again into small, weak surf for the rest of the period.
So for this stretch: pass on the first week. The only real standouts are the glassy morning on the 3rd for absolute beginners, and the clean offshore days on the 5th, 6th, and especially the morning of the 8th of September. The 8th is your best bet for a solid, clean wave.
Rusty.
