The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for Dongara-Port Denison over the next couple of weeks.
First up, we've got a solid run of swell, but the wind’s gonna be the story early on. The water’s about what you'd expect for this time of year, no major temp surprises.
The first decent call is Thursday morning, the 13th. We've got a clean 8 ft SW groundswell with a very long 15-second period, and a light offshore breeze from the ENE. The energy is pumping (3686). This is serious wave size though, over 8 ft, so we're lookin' at a day for experienced surfers only. The long period will make it wrap nicely into the reef here, but expect some big lulls between sets.
Friday morning the 14th is similar again – 8 ft SW, 16-second period, clean with a 12 mph offshore from the ENE. Again, big, powerful, for the experts (3624). The afternoon on both these days gets chopped up by a southerly cross-shore.
We hit a bit of a messy patch from Sunday the 16th through to Monday the 17th. Afternoon winds on Sunday are cross-shore, and Monday gets completely blown out with onshore and cross-onshore winds. Not worth paddling out.
Now, here’s the standout. Tuesday morning, the 18th of August. This is the one to circle. A huge 13 ft SW groundswell (16 sec) with a clean offshore breeze from the E at only 6 mph. The energy reading is massive at 7953. This is exceptional, but also in the "expert only" zone. That size on a reef with a long period will be a sight to see, but you better know what you're doin'.
Wednesday the 19th is a write-off with strong westerly onshores. But then we get another beauty – Thursday morning, the 20th. The wind goes glassy, absolutely dead calm, and we still have a solid 12 ft SW swell (15 sec). It’s glassy clean (4811). This is a big, clean, powerful day for the crew that can handle it.
After that, we go through a bit of a lull. From Friday the 21st through to Sunday the 23rd, the swell drops a little but stays rideable. The 23rd (Sunday morning) is tidy – 10 ft SW, 16-second period, with a moderate offshore from the ENE (4062). That's a solid, clean option for the experienced surfer.
The real monster might be lurking on Tuesday the 25th of August. That morning shows an 12 ft WSW swell with an 18-second period, but a light cross-onshore breeze. The energy reading is off the charts at 11189. The afternoon is cleaner with a cross-shore wind. This is an enormous groundswell – one for the tow crew or the brave paddle-in experts at the peak.
Wednesday the 26th morning cleans up nicely with a cross-offshore wind and an 12 ft SW swell (17 sec, 6187). Another exceptional, powerful day for those with the skills.
The last few days of the window drop off in size and quality, with smaller swells and cross-shore winds making things average.
Bottom line: If you’re an experienced surfer, the standout is Tuesday morning the 18th for that massive, clean 13 ft SW. The glassy Thursday morning the 20th is also top-tier. Keep an eye on Tuesday the 25th for something truly massive, but the wind might be just a little scratchy. For the average punter, there’s not much in this window that’s user-friendly due to the size.
Catch ya later,
Rusty
