Dunes Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it.

We’ve got a solid 16-day window shaping up, but it kicks off with a bang. The opening act is a bit of a wild one, so pay attention.

The standout session is the very first one: Wednesday morning, August 19th. Dunes is pumping. We’re looking at a strong 7ft swell from the WSW, but here’s the kicker – it’s a long-period groundswell at 16 seconds, and the combined energy is a hefty 2234. That’s a lot of power. The wind is a gentle offshore from the SSE, so the face will be clean. The report flags it as too big for this break, and at 7ft, it’s definitely headed into expert territory. This is a reef setup, and with that period, it’s going to be a proper, powerful wave. If you’re not experienced, sit this one out and watch the show.

Things settle down a touch but stay good. Wednesday afternoon goes glassy – 0 mph wind – with a 7ft WSW swell. The energy is still high at 1880. It’s called excellent for experienced surfers. That’s two brilliant sessions in a row to start the week.

Thursday morning, August 20th, the swell drops to 5ft from the SW, period still a long 15 seconds, with a moderate offshore from the SE. Energy is 930 – moderate – and conditions are described as very good. A more manageable size for a wider range of surfers.

Friday morning, August 21st, brings another good one: 5ft SW swell, 16-second period, gentle SSE offshore, and energy at 1087. Clean and excellent for experienced surfers again.

Saturday morning, August 22nd, the swell is 4ft from the SW, 14-second period, with a gentle SSE offshore. Energy is 730. It’s a very good session, a bit smaller but still clean.

After Saturday, the surf drops off. Sunday the 23rd and Monday the 24th have swells around 3ft, but the wind is messy. There’s a gap of a few days where the quality dips, with onshore and cross-shore winds making things choppy.

We see a pulse pick up again on Thursday, August 27th. The morning has a 6ft SW swell with a 16-second period, and a cross-offshore wind from the S. The energy is back up to 1469. The report calls it marginal, but with that size and period, it’s a lot of water moving around. This one is for experienced surfers who know the reef.

The window closes out with a couple of things to keep an eye on. Sunday, August 30th, the morning has a 4ft WSW swell, 16-second period, and a clean SSE offshore. Energy is 731. It’s called very good surf. Then, a week later, Thursday, September 3rd, the morning shows a 5ft SW swell, 16-second period, light S wind, and energy at 906. That’s very good, but it’s a long way out – treat it as a promising but not locked-in call.

As for the water, it’s about average for the time of year, so no need to dig out the thickest suit.

Remember, Dunes is a reef break that’s consistent, and it’s exposed to the SW. It’s a spot that can get crowded, especially when it’s this good.

Rusty, signing off.
