The Lowdown
Alright folks, Rusty here. Let’s get into the outlook for Dongara-Port Denison.
The next couple of weeks are going to be a bit of a rollercoaster, with some seriously big swell on the horizon. We’ve got a solid run of surf coming, but there’s a lot of wind to deal with. The water is sitting at 66°, which is a bit colder than normal for this time of year, so pack a good steamer.
We start on Friday, July 31st, with the first wave of the period. The swell is already 7ft from the SW, with a very long period of 16 seconds. That’s proper groundswell energy, and the combined energy is a strong 2568. The problem is the wind is onshore from the WSW at 6 mph, making conditions a bit messy. The tide might be an issue too, so it’s not a classic Friday arvo.
Saturday morning, August 1st, looks much cleaner. The wind swings to a light cross-offshore from the SE at 6 mph, and the swell is still a solid 7ft from the SW. The period drops to 15 seconds, still a quality groundswell. This is a good window for experienced surfers. The afternoon gets a bit windier with a SSE breeze at 12 mph, so get it early.
Sunday, August 2nd, has a bit more size. The morning sees 8ft SW swell with a 14-second period, but the wind is a stiff cross-offshore from the ENE at 16 mph. It’ll be clean but pushy. The afternoon settles down with a light SSE breeze, making it a better bet for the later session.
Monday, August 3rd, the swell drops to 6ft, but the wind goes all over the shop. Morning is a cross-shore from the NNW, and the afternoon brings a cross-onshore and risk of thunderstorms. Not great.
Tuesday, August 4th, is a write-off. Strong onshore winds and a big 8ft to 10ft SW swell with a messy, choppy surface. Combined energy is a massive 4695 in the afternoon, but it’s all windslop.
The first real standout hits on Wednesday, August 5th. The morning is glassy. The wind is a whisper from the WNW at 3 mph, absolutely glass. The swell is a solid 8ft from the SW with a 16-second period, meaning 3678 of combined energy. This is a magic window for experienced surfers – clean, powerful, and lined up. The afternoon is still good, but the wind goes cross-onshore, so the morning is the session.
Thursday, August 6th, the swell jumps to 10ft, but the wind is onshore all day, so it’s blown out.
Friday, August 7th, the swell bumps up to 12ft from the SW. The wind is cross-shore in the morning from the SSW, and cross-onshore in the afternoon. It’s powerful, but the wind is going to make it lumpy. Only for the experienced.
Saturday, August 8th, is a total mess. Strong winds in the morning and fresh cross-shore winds in the afternoon. The swell is 10ft to 12ft, but the surface is terrible. Kite-surfing weather.
The next true standout is Sunday, August 9th, but it’s a monster. The morning brings a 16ft SW swell with an 18-second period, and the combined energy is a staggering 16445. The wind is light offshore from the ENE. This is a massive, powerful groundswell. It’s too big for this break. Only absolute experts with big-wave gear should even think about it. The afternoon is even bigger at 18ft.
Monday, August 10th, the swell drops to 12ft, but the wind is a light cross-offshore from the ESE. The morning is clean, with 7591 of energy. Still big, but much more manageable for experienced surfers. This is a great session.
The rest of the second week sees a lot of swell in the 7ft to 16ft range, but the wind is often a problem. A standout morning on August 13th looks promising with a 8ft SW swell and a light offshore from the ENE, giving clean conditions. August 14th has a solid 15ft swell with light winds, but it’s cross-onshore, so there will be some ripples. The 15th has big 16ft swell but onshore winds.
So, the two best windows are the glassy morning of Wednesday, August 5th, and the clean, powerful morning of Monday, August 10th. For the first one, get the 8ft SW groundswell with glassy conditions. For the second, grab the 12ft SW swell with light offshore winds. Both are for experienced surfers.
