The Lowdown
Alright folks, Rusty here. Let’s get into it for Dongara-Port Denison. This is a solid reef setup that likes a good W swell, and we’ve got a run of strong, long-period groundswells lining up. The water is sitting at 66°, which is pretty much bang on average for this time of year, so no surprises there.
The first real glimmer of quality comes in on Sunday the 30th. The morning is where it’s at – a clean 8ft SW swell with a very long 19-second period, and barely a breath of wind from the NE. That’s serious energy pushing in (combined energy of 3934), and it’s going to be absolutely glassy. This is for experienced surfers only though, as it’s pushing into that bigger range. The afternoon sees a slight onshore kick from the WSW, which will put a bit of a ripple on it, but the morning is the standout of the whole outlook.
Monday the 31st is a write-off with onshore wind, so skip it. Tuesday the 1st of September cleans up in the morning with a 6ft SW swell and a cross-off breeze from the SSE, offering clean, lined-up waves for the more experienced crew. Wednesday the 2nd is similar, with a clean 7ft SW swell in the morning and light cross-off winds.
Now, the real gem for the second week is Thursday the 3rd of September. We’re looking at a 8ft SW groundswell with a 15-second period, and the wind is forecast to be dead glassy from the SW in the morning. That’s as good as it gets for a reef – zero wind, clean face, and plenty of punch. The combined energy is 2208, so it’s got some grunt. Again, this is expert territory at that size.
The following week, from the 4th to the 6th, sees a mix of lumpy cross-shore winds and some bigger, choppier swells. Friday the 4th is a write-off with strong winds. Saturday the 6th has a massive 12ft SW swell, but it’s a bit messy. Sunday the 7th is the real standout for the second week – a 10ft SW swell with a 16-second period and a clean offshore breeze from the E in the morning. That’s a proper, powerful, groundswell with clean conditions. The combined energy is a huge 4489. This is for experts only, and it’s going to be a serious session.
After that, the westerly winds start to mess things up. The 8th and 9th are marginal, and by the 11th we’re looking at another big pulse of 10ft SW swell, but onshore winds will spoil the party. The 12th and 13th see the swell jump to 13ft, but with strong cross-onshore winds, it’s going to be a washing machine. That setup is way more interesting for kite surfing than a paddle session.
Overall, the best bets are the Sunday 30th morning, the Thursday 3rd morning, and the Monday 7th morning. Those are the standouts. Expect crowds at this spot, so get in early.
Rusty.
