Eerste Steen Surf Forecast and Surf Report

Alright, Rusty here, let’s take a look at what’s on offer at Eerste Steen for the next few weeks.

Right off the bat, we’ve got a serious cold water situation. The ocean is sitting at 12°, which is a massive 4° colder than usual. That’s very unusual, so if you’re paddling out, you’ll want a thick suit and maybe some booties.

The good stuff kicks off on Sunday, September 6th, but the morning is a bit of a tease. We’ve got a solid 7ft SW groundswell with a long 18-second period pushing through, and the combined energy is pumping at 2899. The problem is an ESE cross-off wind at 12 mph and questionable tide conditions, so it’s on the marginal side for most. For the experienced crew, the afternoon cleans up nicely—6ft SW swell, 16-second period, lighter 6 mph ESE wind, and the energy is still strong at 1806. That’s your window for a proper session if you know what you’re doing.

Now, if you want the standout of the whole outlook, it is hands down Monday morning, September 7th. This is the one to circle. The wind goes glassy at just 3 mph from the west, the swell is a clean 7ft from the SW with a solid 14-second period, and the combined energy is a strong 1505. For a spot like Eerste Steen that’s fairly exposed to SW swell, this is as good as it gets. The water is still cold but the surf will be absolutely pristine. Keep in mind, with this size, it’s getting toward the steeper end for beginners—more of an intermediate-to-expert level session.

Monday afternoon sees a shift: a cross-on 6 mph SSW wind kicks in, the swell drops to 6ft with shorter 13-second period, and quality drops off fast.

Tuesday morning, September 8th, is a small window of glass again with a west wind at 3 mph, but the swell has dropped to 3ft from the WSW at a shorter 12 seconds. Energy is down to 476. It’s clean but small—worth a paddle if you’re desperate, but not a standout.

From Tuesday afternoon through Wednesday the 9th, we go into a lull. Swells below 3ft, onshore and cross-shore winds, and poor to marginal conditions. Not worth getting wet.

Thursday, September 10th, the swell jumps back up big time. The morning sees a 10ft SW groundswell at 16 seconds, with combined energy roaring at 4875. That’s serious power. But there’s a catch—wind is SSE at 12 mph with a cross direction, so it’s lumpy. This is expert territory only, and even then, it’s a bit of a battle with the chop. The afternoon is similar with a 10ft WSW swell, 15 seconds, and 3464 energy, but winds increase to 16 mph. This setup is more interesting for kite surfing than a clean paddle session.

Friday and Saturday (September 11th and 12th) stay in the 6ft to 8ft range with SW swells and cross-off winds keeping things clean in the mornings, but there’s always that marginal tag. The consistency is there but the quality isn’t electric.

The second week sees a drop in overall quality. From September 13th onward, we get a mix of messy cross-shore winds, building onshores, and lumpy conditions. Swell sizes bounce between 4ft and 8ft, but the wind is never truly in our favor. The morning of September 15th has an 8ft WSW swell and 12 mph cross wind—still messy. The real dud is September 17th, when 10–12ft WSW swells meet 25–28 mph SSE cross winds. That’s a washing machine, not a surf session.

We finish off the outlook on September 20th with a small but clean window: Sunday morning has a 4ft SW swell at 13 seconds, glassy cross-off wind from the NNW at 6 mph, and a combined energy of 451. It’s tiny but it’s clean—a longboard kind of morning.

Overall, the standout is Monday morning, September 7th. Mark it. The rest is a mixed bag of occasional clean windows and a lot of wind-affected, lumpy swell. Don’t sleep on that glassy morning session.

Stay warm out there.
