The Lowdown
G'day, Rusty here, and I've got the dope on Dongara-Port Denison. We've got a solid run of surf coming through, but you've got to pick your moments. The pattern is a classic winter swell train from the south-west, but the wind is the real character in this story.
We kick off Wednesday the 22nd with a clean 6 ft SW groundswell coming in from the south-west, with a period of 13 seconds. The easterly offshore breeze is blowing at 12 mph, so the reef at Dongara-Port Denison is looking pretty clean. The combined energy is solid at 961 (moderate), and it's a nice opener. The water temp is about average for this time of year. Thursday the 23rd is the real standout. The morning brings a 7 ft SW groundswell with a 14-second period, and a fresh 19 mph easterly offshore. That's a bit of juice, but it's the afternoon that's the pick: 6 ft of clean SW swell, with a gentle 9 mph offshore from the ESE, and the energy jumps to 1402 (moderate to strong). This is the best session on offer – clean, powerful, and all yours, though crowds are possible at a spot that's fairly consistent. For the more experienced crew, that morning 7 ft with the fresh offshore is also a cracker.
Friday the 24th drops off a touch to 4 ft in the morning with a cross-off breeze, but the afternoon cleans up with a 4 ft SW swell and a gentle offshore. It's still a fun wave. Saturday the 25th is smaller, around 4 ft, and the wind swings around, so it's a bit of a write-off. Sunday the 26th gets messy with a cross-shore wind and a bit of rain. The afternoon shows a 6 ft SW groundswell with a long 16-second period, but the cross-shore wind at 12 mph puts a chop on it. The energy is 1708 (strong), but it's not clean.
Now, Monday the 27th is back on. The morning delivers a solid 7 ft SW groundswell with a 13-second period and a clean 12 mph ESE offshore. The energy is 1693 (strong), and it's punching. This is for the experienced crew – it's a big, powerful reef wave. The afternoon stays good with a 6 ft swell and gentle offshore. Tuesday the 28th has a 7 ft SW swell in the morning, but the wind is cross-off, so it's still workable. The afternoon is the gem: 6 ft with a glassy 3 mph ESE breeze and a 14-second period, energy at 1722 (strong). That's a beautiful, clean session.
We hit a bit of a lull from Wednesday the 29th through to Thursday the 31st. The swell hangs around, but a north-westerly wind brings in the chop and cross-onshore conditions, making it a mess. The 19-second period on the 29th is a long one, but it's wasted on the wrong wind. Friday the 1st of August and the weekend are a write-off. A massive 12 ft to 16 ft SW swell rolls in, but with onshore gales of 22 to 34 mph, it's a complete mess. The energy is scary high, hitting 5299 and even 19622 (very strong), but it's a washing machine. Kite surfers might be loving it, but for a paddle surfer, it's a hard no.
The surf starts to settle down a bit from Tuesday the 5th of August. A 5 ft SW groundswell with a 16-second period and a light 6 mph offshore from the ENE on Wednesday morning. That's a beautiful, clean, long-period swell. The energy is 1829 (strong), and it's a great option for experienced surfers. Then, Thursday the 6th of August morning is the absolute pick of the second week. A 10 ft WSW groundswell, 13-second period, and a glassy 6 mph ESE offshore. The combined energy is 3499 (strong to very strong), and it's clean. This is a big, powerful, clean reef wave for the experts only. The long-range promise is there, but it's a bit further out, so keep an eye on it.
This is a spot that's fairly consistent, so a blank run is unlikely. The first week has the best windows, so get out there when the wind is your friend.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Dongara-Port Denison may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
