The Lowdown
Alright folks, Rusty here. Let's have a look at what Dongara-Port Denison has in store for us.
Right off the bat, we have a gap in the action. Monday the 17th is a write-off with a fresh cross-onshore breeze and lumpy, poor conditions. We have to wait until Tuesday morning for anything worthwhile. The first real standout is Tuesday morning, the 18th of August. We're looking at a solid 12 ft swell from the WSW. The kicker is the glassy conditions, with zero wind. This is exceptional surf for expert surfers only, as 12 ft is well over the 8 ft mark for the big dogs. The combined wave energy is pumping at 7178 units. This is a reef break, and it is fairly consistent, but expect crowds sometimes. Get on it if you've got the experience because it doesn't get much cleaner than glass.
We then settle into a few days of cleaner but smaller surf. Wednesday the 19th has an 8 ft SW swell with glassy conditions again in the morning for experienced surfers, but the combined energy drops to 2962. Thursday the 20th and Friday the 21st both offer clean, 8 ft to 10 ft SW swells in the morning with light cross-offshore winds from the ESE, so the shape should be there for experienced surfers. The water temp is about average for this time of year.
The second week sees a drop in quality. Saturday the 22nd has a smaller 5 ft SW swell but it gets messy in the afternoon. We have a run of marginal and poor conditions through to Friday the 28th, with wind and lumpy seas. A big pulse of swell shows up on Wednesday the 26th, with a massive 18 ft SW swell, but the onshore wind is howling at 19 mph and the combined energy is a huge 11375. It's a complete mess. That sort of setup at a beach and reef break looks more interesting for kite surfing than paddle surfing.
The outlook ends with some hope. Saturday the 29th of August morning, clean conditions return with a 5 ft SW swell and a gentle cross-offshore breeze. Then Sunday the 30th morning has a clean 7 ft WSW swell with light offshore winds. These are solid options for experienced surfers, but remember it's a 16-day outlook so the details are less certain that far out.
Rusty, signing off.
