Denhams Beach Surf Forecast and Surf Report

G’day, Rusty here. Look, I’m gonna level with ya – this outlook for Denhams Beach is a real mixed bag, mostly flat and frustrating, but there are a couple of windows where it might just come together. We’ve got a 16-day window here, and the first solid recommendation doesn’t pop up until Monday the 14th of September, so we’re starting with a bit of a gap.

Monday, September 14th (afternoon): We finally get something to work with. The water’s sitting at 64°, which is a touch warmer than normal for this time of year – not a bad start. Swell is a small 4 ft from the NE, but the period is a short 7 seconds, so it’s not gonna have much grunt. The real story here is the wind: a light 6 mph from the NNW, blowing cross-offshore. That’s the kind of breeze that cleans things right up, and the wave comment says “clean.” It’s surfable, but ordinary. Still, it’s all we’ve got, so if you’re desperate for a paddle, this is your shot. Just don’t expect any barrels. Energy is weak (155).

Then we hit a massive dry spell. From Tuesday the 15th right through to Monday the 21st of September, it’s pretty much a write-off. Most sessions are getting zeros or poor conditions – onshore wind, tiny swell, or total mush. Tuesday afternoon the 15th has 16 mph southerly cross-shore wind ripping into 2 ft surf – that’s just a washing machine. Even when the wind goes glassy on Thursday morning the 17th, there’s zero energy (7). For over a week, it’s flat city.

Tuesday, September 22nd (morning): This is where things pick up for the more experienced crew. Swell jumps to 6 ft from the SSE with a 10-second period, pumping moderate energy (614). The catch is the wind is a light cross-onshore from the ENE at 6 mph, which will put a few ripples on the face. It’s a marginal call, but there’s enough there for a session.

Wednesday, September 23rd (afternoon): Now this is the standout – but only for experts. We’re looking at a beast of a swell: 12 ft from the NE with a short 7-second period. That’s a lot of water moving fast, and the combined energy is massive (1139). The wind is a light cross-shore from the NNE, which is okay. But the wave comment says the swell is predicted to be too big for this break. This thing is going to close out and be heavy. If you’re not an experienced surfer on a big board, stay well away. This is strictly for the chargers who know the bank.

Thursday, September 24th (morning): This is the best all-rounder of the whole period. Swell drops to a more manageable 6 ft from the NE (8-second period, moderate energy at 435), and the wind switches to a light 6 mph cross-offshore from the NNW. Conditions are “clean.” That’s your window for a quality session with shape and power. The crowd factor for Denhams Beach is listed as “sometimes,” so you might see a few others, but it shouldn’t be a scrap.

Saturday, September 26th (morning): Another decent option for the last part of the run. Swell is 5 ft from the NE (8 seconds, moderate energy at 269) and the wind is glassy – 3 mph from the NNW. That’s as clean as it gets. The comment says “expect good surf conditions,” so this one is worth an early alarm. The crowd is “sometimes” again, so get in early for some clean ones.

After that, it fades back into smaller onshore mush through to the end of the period. A few clean but tiny mornings on the 29th, but not enough to get out of bed for.

So, bottom line: If you’re a beginner, Monday the 14th is your only half-decent shot, but it’s small. For the experienced crew, the morning of Thursday the 24th is the standout – don’t miss it. And keep an eye on Saturday morning the 26th for glassy clean lines. Everything else is a pass.

Rusty.
