Guethary - Les Alcyons/Avalanche Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the table for Guethary's Les Alcyons/Avalanche. It’s a solid reef setup that takes a west swell, and it’s an expert-only wave, so don’t even think about paddling out unless you’ve got the chops.

The water temp is sitting right around average for the time of year, so nothing wild there.

Right now, the start of the period is flat, dead flat. We’re looking at a gap of a few days with nothing worth paddling for. The first real sign of life pops up on Thursday morning, 27th August. That morning we’ve got a 4ft swell from the WNW, with a weak period of 8 seconds, and the wind is a light cross-offshore from the SSE. The combined energy is only 188 (moderate), but it’s clean. The score is low though, so it’s just a tease.

The next few days are a write-off – messy winds, onshore junk, and the swell is either too small or blown out. Friday and Saturday look particularly rough with moderate to fresh cross-onshore winds and lumpy conditions.

Now, here’s the first proper standout. Monday morning, 31st August. The wind goes glassy, dead calm, with a 5ft swell from the WNW, period picking up to 9 seconds. The combined energy is 338 (moderate). It’s clean, it’s glassy, and it’s consistent. This is the best of the early run. The crowd factor is "often" here, so expect a few others who’ve been waiting for the same window.

Then Tuesday morning, 1st September, is another nice one. A light cross-offshore from the ENE, 4ft from the WNW, 9-second period, and the energy is 282 (moderate). That’s clean, surfable, and should be a good session.

The long-range stuff is where it gets interesting but a bit more uncertain. Saturday morning, 6th September, the swell jumps to 5ft from the NW, period 11 seconds, and the energy hits 564 (strong). But it’s onshore and marginal. Not a standout.

The real standout of the whole 16-day window is Tuesday morning, 8th September. Dawn patrol, glassy as can be, with a 8ft swell from the NW, 10-second period, and the combined energy is a massive 1832 (strong). That’s excellent surf for experienced surfers. The wind is glass, the wave is stacking up. This is the one to circle on the calendar. Just remember, it’s still a week and a half out, so keep an eye on it, but it’s got the makings of a proper session.

Rusty.
