The Lowdown
G’day, Rusty here. Let’s have a look what’s shaping up for Dongara-Port Denison. The water temp is running about average for the time of year. There’s a bit of a wait for the real standouts, but there are some promising windows if you pick your mornings.
Kicking off Sunday the 13th, it’s a bit average with a 7ft SW swell, but the wind is cross-on and light, making for small wind ripples. The wave energy is moderate (2004). Not terrible, but not one to get excited about. Monday the 14th morning is a big step up – 8ft SW swell, clean conditions with a gentle cross-off breeze out of the SSE, and the energy is climbing (2263). ‘Excellent surf for experienced’ is the call. The swell is over 8ft in the afternoon but the wind gets messy.
Tuesday the 15th morning is a true standout. You’ve got a clean 8ft SW swell with a glassy offshore ESE breeze, minimal wind. The waves are clean, the energy is solid (2383) – this is the pick of the first week. Head to Dongara-Port Denison early.
Wednesday the 16th still has a clean 6ft SW swell in the morning, but it’s smaller. Thursday the 17th drops right off with poor conditions and cross-on wind – a definite skip. Friday the 18th is blown out with strong wind and lumpy surf.
Saturday the 19th is bigger again at 8ft SW but the wind is cross and moderate, creating chop. Sunday the 20th morning sees a clean, gentle offshore ENE breeze with a 7ft SW swell and moderate energy (1438) – another good, cleaner window.
The second week kicks off Monday the 21st with a solid 8ft SW swell but cross wind. Wednesday the 23rd is a big one – 10ft SW swell with a very long 18-second period, proper groundswell. Energy is strong (5196). This is a high-quality, expert-only zone. The wind is light though, so there will be some good ones on the reef if you know what you’re doing. Thursday the 24th stays big at 8ft but with cross-on chop.
Friday the 25th pushes even bigger – 12ft SW swell, but the period drops to 13 seconds, and the wind is light cross-on. Energy is still strong (4696), but the quality is marginal. Saturday the 26th morning is another clean window – offshore E breeze, 8ft SW swell, clean faces (2680). Sunday the 27th goes downhill with stronger winds.
The best on offer? Tuesday 15th September morning at Dongara-Port Denison – clean, offshore, 8ft SW, and excellent. Also, Wednesday 23rd September for the experts: big 10ft SW with 18-second period, light wind, and solid grunt.
Rusty.
