The Lowdown
G'day, Rusty here, looking at the next couple of weeks for Dongara-Port Denison. We've got a bit of a mixed bag, with some real clean windows if you're patient, but also some proper gnarly, blown-out days to dodge.
The first few days are a write-off, honestly. Wednesday the 15th has some size but the wind is messy, and by Thursday the 16th and Friday the 17th it's just a choppy, lumpy mess with howling cross-onshore winds. You'd be a mug to paddle out. Saturday the 18th sees a big jump in size, but it's still too cross-onshore in the morning; the arvo cleans up a bit, but with 12ft of swell it's a serious mission (combined energy of 6631, strong to very strong).
The real standout, and what I'm looking at, is Sunday the 19th. The morning session is the pick of the whole outlook. We've got a solid 8ft SW groundswell, with a long 15-second period, and a light S wind making it cross-off and clean. That's excellent surf for experienced surfers. The energy is solid (2994) and the conditions will be glassy. The S wind is light, so it should be clean. The optimum swell direction is from the west, so this SW groundswell is a good match for this reef break. It's a fairly consistent spot, but it can get busy, so expect some company.
Monday the 20th is also a cracker. The morning has a 6ft SW swell with an easterly offshore wind, making it clean. The afternoon is the real gem: light variable wind, glassy conditions, and a 6ft SW swell. For a reef break, that's as good as it gets. The water temperature is about average for the time of year.
The following week gets a bit more up and down. Wednesday the 22nd has a decent 7ft SW swell with a clean offshore ESE breeze in the morning. Thursday the 23rd is solid, with a 8ft SW groundswell and a 16-second period, and an offshore E wind in the arvo. The 25th and 26th drop right off in size, down to 2ft to 4ft, though the 26th has a very long 21-second period which is better suited to the reef. The 27th through the 29th see a return of some clean, lined-up swell in the mornings and afternoons, with offshore and cross-off winds, but the size stays around the 3ft to 6ft mark. The 30th is a write-off with fresh cross-onshore winds.
The real standout is Sunday the 19th morning. The backup is Monday the 20th afternoon for the glassy conditions. After that, the 22nd and 23rd mornings are worth a look if you can handle the size.
Rusty.
