The Lowdown
Alright, Rusty here, let's look at what's cookin' for Dongara-Port Denison, in feet and miles per hour.
There's a serious run of strong, long-period groundswells on the charts, but we're gonna be picky with the wind. The water's about 65°F, which is a couple of degrees colder than normal for this time of year, so you'll feel that chill. This is a reef break, so clean conditions are everything, and those windows are gonna be the ones to chase.
The action kicks off on Thursday the 13th. Thursday afternoon we get a big 10ft SW swell with a 17-second period – that's proper groundswell energy (4312). The wind is cross-off, so it's not terrible, but it's not the best. Friday morning the 14th is where it starts to fire. The swell eases a little to 8ft from the SW, still with a long 16-second period, and we get offshore wind. That's your first real standout – clean, powerful, lined-up waves on the reef. That's for the experienced crew. Saturday morning the 15th has 6-7ft SW with a cross-off breeze and a shorter 14-second period. It's surfable, but not the quality of Friday.
Monday the 17th is a total loss with strong onshore winds. Don't even bother. The absolute standout of the whole forecast is Tuesday morning the 18th. We're looking at 11-12ft of SW swell, period a solid 16 seconds, and the energy is massive (6465). The wind? Dead calm. Glassy. For a reef break, that is pure perfection for expert surfers. That is the day to be a local.
There's a little lull mid-week, but another good window opens Thursday morning the 20th. Another 11-12ft SW swell, 16-second period, huge energy (6674), with a light cross-shore wind. It'll be good, but not as clean as Tuesday. The weekend of the 22nd and 23rd sees smaller, cleaner swells in the mornings (around 7ft and 5-6ft) with glass or offshore wind, great for a fun session. The run after that gets messy with strong westerlies starting the 24th.
The one you really mark on the calendar, though, is Thursday morning the 27th. A 10ft SW groundswell with a 17-second period, and the energy is off the charts (8161). The wind is completely calm, glassy as a mirror. That is exceptional, elite-level conditions for the experts at this reef. It's a long way out, but that is the session to dream on.
