Thompsons Bay Surf Forecast and Surf Report

Alright, Rusty here. Let's have a look at what's coming up for Thompsons Bay.

We're looking at a bit of a slow burn for the next couple of weeks. The water temp is sitting around 69°, which is about normal for this time of year, so no surprises there. The first few days are pretty ordinary, with a lot of onshore wind and messy conditions, so don't rush down there right now. The real standout in this whole period is Monday, September 7th.

That Monday morning is looking like the pick of the bunch. We’ve got a solid 10ft south swell rolling in with a very long 17-second period, and the wind is glassy. That's about as good as it gets for clean conditions. The combined energy is massive at 5344, so there's a heap of power behind it. That said, with that size and period, this is for experienced surfers only – it'll be too big and punchy for beginners. The swell direction is south, which is a good match for the spot's optimum.

Monday afternoon is still decent with 8ft south swell and a cross-off wind, keeping things clean. It's a step down in energy but still a fun session for those who know what they're doing.

After that, it’s a long stretch of pretty poor conditions right through until mid-September. There's a lot of cross and cross-on wind, short-period windswell, and choppy, lumpy water. It’s not going to be worth paddling out unless you’re desperate. We’re talking a solid week or more of mediocrity.

There’s a slight glimmer on Tuesday, September 15th, with a glassy afternoon and 4ft waves, but the conditions are just ordinary. Then on Wednesday, September 16th, the afternoon sees a big 10ft east-northeast swell but with a cross-on wind, making it messy again.

The final call is Monday, September 21st. We’ve got an 8ft south swell in the morning with a cross-shore wind, and then a 10ft south swell in the afternoon with an offshore wind. The combined energy is strong in both sessions (1652 and 1635). This looks promising, but it's far out, so keep an eye on it. Again, that size is expert territory.

So, to sum it up: if you're looking for the best, it's Monday morning, September 7th. Glassy, big, and powerful. That's your one to circle. The rest of the run is mostly a write-off until maybe that last Monday on the 21st. This is a spot that can be inconsistent, and we're seeing that here. It’s a long gap between good sessions.

Rusty.
