Thompsons Bay Surf Forecast and Surf Report

Alright folks, it’s Rusty here, and I’ve been staring at the charts for our little stretch of coast. Let’s be real, the next couple of weeks are a mixed bag. We’ve got a few promising windows, but you’ll need to be patient and pick your moments. The first few days look rough, but there’s some serious potential on the horizon if you know where to look.

We start off the outlook on Saturday the 5th of September, but it’s not looking good. The wind is a nasty cross-on at 9 mph, and the swell is a messy 7ft from the SSE. It’s choppy and poor, with combined wave energy sitting at 990. Not worth paddling out. Sunday the 6th is a different story. The swell drops right down to 3ft from the SSW with a solid 11-second period, but the real winner is the wind. It goes glassy. That’s right, a flat calm, 3 mph Easterly breeze. The water is about average for this time of year, and the energy is a modest 481. It’s not going to be pumping, but for a small, clean session, Thompsons Bay will be a dream. It’s a sheltered spot, so this small swell might just offer up a few fun, clean lines.

Now, hold onto your boards, because Monday the 7th of September is the standout. The morning brings a solid 10ft groundswell from the S with a massive 17-second period. That’s very long-period energy, folks, and it’s pushing a combined wave energy of 5534. That’s a lot of power. The wind is a clean cross-off from the NNE at 9 mph. This is going to be excellent for experienced surfers only. It’s a big, powerful, clean swell. The long period means it’ll be handling beautifully at Thompsons Bay, a sheltered spot, but it’s not for the faint of heart. The afternoon looks a bit more marginal as the wind picks up to 16 mph, so get on it early.

After that, we get a long, ugly stretch. From Tuesday the 8th right through to the end of the first week, it’s a write-off. The wind is onshore or cross-shore, and the swell is a jumbled mess. There’s a mix of windswell and short-period stuff, and the energy is all over the place but the conditions are just poor. You’ll be fighting chop and strong breezes.

The second week offers a couple of glimmers. Friday the 11th of September afternoon shows a glassy 6ft swell from the ENE with a 9-second period. That could be a nice, clean, mellow session. Then Saturday the 12th gets a bit bigger, but the wind is up and the quality is only marginal. The real other potential is on Wednesday the 17th of September. The morning sees a 7ft swell from the ENE with a decent 10-second period, and the wind is a clean cross-off from the SW. The energy is a healthy 1349. The forecast says marginal, but with that wind, it could actually be a cracking morning session for anyone who can handle a mid-sized swell. The long gap in quality surf makes this a promising, if uncertain, target.

The very end of the run, on the 18th and 19th, fades out. The swell drops right off, and the wind gets messy again. It’s back to small, weak, or blown-out conditions.

So, if you want the best wave of the outlook, it’s the Monday morning (7th September) at Thompsons Bay. It’s a big, powerful, clean swell for experts. For a smaller, more relaxed, and guaranteed clean surf, you can’t beat the glassy Sunday morning (6th September). Keep an eye on that Wednesday the 17th too, it might just surprise you.

Stay stoked,
Rusty
