Guethary - Les Alcyons/Avalanche Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the menu for the coming weeks at this spot.

Right now, it’s flat and messy. We’ve got a bit of a dry spell to start. The first real chance of a wave doesn’t show up until the morning of Sunday the 13th. Before that, it’s just small, choppy, or glassy but flat. Basically, not worth paddling out.

The standout window is the morning of Sunday the 13th at Guethary - Les Alcyons/Avalanche (reef). The water is sitting at 74°, which is a solid 5° warmer than normal for this time of year – that’s a very unusual warmth, so the water feels like a bath. The swell is a clean 4ft from the NW with a long period of 13 seconds. That’s proper groundswell, offering well-shaped waves with good energy and long lulls between sets. The wind is glassy, which is a massive positive, meaning the surface will be clean as a whistle. The combined energy is moderate (545). This is the best on offer – a true stand-out morning for those who know this reef.

The rest of the week is a mixed bag. Monday the 14th morning still has a decent 4ft NW swell with a 12-second period, and a light offshore wind from the east, so it’ll be clean (energy 469). But the wind shifts onshore later in the day. Tuesday the 15th is a write-off with strong onshore winds and a choppy 6ft swell. Wednesday the 16th is rain showers and onshore wind, not great.

Then we get another good look on the morning of Thursday the 17th. Another 6ft NW swell, 10-second period, and glassy conditions. The energy is moderate (592) and the surf will be very good, but the swell is creeping over 5ft, so it’s getting a bit more serious.

The real fireworks are on the morning of Monday the 21st. This is over a week away, so it’s a promising long-range call, but less certain. The forecast shows a 6ft NW swell with a 13-second period, and light offshore east wind. The combined energy is very strong (1162). That’s a lot of power. For experienced surfers, this could be an excellent session. For beginners, it will be too big and powerful.

After that, the energy drops back down, with a few more clean mornings on the 22nd and 24th, but nothing that matches the punch of that 21st morning.

So, if you’re looking for the best, set your alarm for the mornings of the 13th and the 21st. The 13th is a sure thing, the 21st is the big one we’re all hoping for.

Rusty.
