Dongara-Port Denison Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming up for Dongara-Port Denison. We’ve got a full 16-day window ahead, but it’s a real mixed bag with a lot of wind and some tricky conditions.

We start off with a decent amount of swell in the water, but the wind is going to be a problem for a while. The first real standout comes later, but you’ll have to be patient.

The first few days, starting Monday 7th September, we’ve got a solid 10ft SW groundswell rolling in with a very long period of 17 seconds. The wave energy is pumping hard at 5180 (moderate to strong). Problem is, the wind is a cross-offshore breeze from the SE at 15 mph, which is keeping the surface clean but the swell is so big and powerful it’s really only for the experienced crew. This is a reef break, so that long-period groundswell will be wrapping in nicely, but at this size it’s a handful and the crowds are possible. The water temp is sitting around 67°, which is about average for this time of year.

Tuesday 8th September sees similar conditions: 10ft at 16 seconds, still a lot of energy (4084 in the morning). The afternoon brings a shift to offshore ESE wind at 19 mph, which should clean it up nicely, but it’s still a big, powerful swell. The quality is marginal overall, with the tide possibly playing tricks.

The swell starts to drop a little into Wednesday 9th and Thursday 10th, but the wind stays strong and offshore, which is a good thing. Swell sizes are still solid at 8ft then 5ft, with periods around 15 seconds. The energy is still moderate (2721 dropping to 1299). The wind is fresh offshore so the waves will be clean, but the overall quality is still tagged as marginal.

Then we hit a bit of a lull. Friday 11th and Saturday 12th the wind turns onshore and cross-onshore, making for choppy, poor conditions. The swell is still there, but you won’t want to be out there. Sunday 13th is similar, with cross-onshore winds and a bit of chop.

The real standout arrives on Monday 14th September. The morning is looking glassy with a light ESE breeze at 3 mph, and we’ve got a clean 8ft SW groundswell at 14 seconds. The energy is 2027. This is the pick of the first week. The water will be clean, the waves will have good shape, and it’s manageable for experienced surfers. It’s the best session on offer in this stretch.

The rest of that week is a bit of a write-off with building onshore winds and cross-shore breezes, until we get to Friday 18th September. This is the big one. The morning shows a massive 12ft SW groundswell with a 16-second period, and energy is through the roof at 5135. The wind is light and cross-offshore from the SE at 6 mph, making it clean. This is exceptional surf, but only for expert surfers. It’s massive and powerful. The afternoon gets blown out by a strong S wind, so get out early.

Saturday 19th and Sunday 20th are smaller and more manageable, but the wind is cross-on for most of it, so the quality drops off.

Then, on Monday 21st September, we see another big pulse of 10ft SW groundswell, with a very long 18-second period, and huge energy at 5522. The wind is light onshore in the morning, so the waves might be a bit lumpy, but it’s a lot of power. This is a long-range call, so keep an eye on it, but it’s promising.

After that, Tuesday 22nd September is a mess with a strong cross-onshore wind and some rain, not worth the effort.

So, to sum it up: the two true standouts are Monday 14th September for a clean, glassy session, and Friday 18th September for the experts looking for a massive, clean swell. Get on it if you can handle the size.

Rusty.
