The Lowdown
Alright mate, Rusty here. Let's get into it.
Alright mate, strap in. We're looking at Thompsons Bay for the next 16 days, and I gotta be straight with you – it's a tough stretch. The opener is rough, and we're waiting a full three days before anything even gets a nod of approval. The early window is just no good. Monday 14th through Wednesday 16th, we're battling a strong, messy cross-shore wind, and that swell is shot through with junk. A solid 12 ft on Monday afternoon (1848 combined energy) sounds punchy, but the north-easterly near-gale ripping across it makes it an absolute chore, not a joy. Kite surfers might be having a field day, but for a paddle surfer, it's a write-off.
Now, Thursday 17th is where things start to take a turn. Thursday afternoon, the stars line up. The wind drops to dead glassy – 0 mph - and we've got a clean 7 ft swell from the ESE. The energy jumps to a solid 1438, and with that glassy surface, this is hands-down the best session on offer. The water temp is sitting at 68°F, which is about 3°F colder than usual for this time of year – you'll feel that little bite. This is the standout window. It's a fairly consistent break, and with glassy conditions like that, you'd be a fool to miss it.
Friday 18th keeps the run going with a glassy morning, 8 ft from the SE (1126 energy). That's another belter of a session. The afternoon gets a bit of a cross-off breeze which cleans it up, but with 8 ft from the SE, it's still got plenty of push. The crowd factor at Thompsons Bay is "sometimes", so expect a few others with the same idea, but the quality on these two days will be worth the company.
The weekend takes a hit though. Saturday 19th and Sunday 20th, the north-easterly is back up, turning that solid 8-10 ft swell into lumpy, cross-shore chop. The energy is high (up to 1726 on Saturday), but it's just not gonna be clean. You could find a sneaky one if you're desperate, but the magic of Thursday and Friday is gone.
After that, it's a mixed bag of onshore and cross-shore winds right through to the end of the window. We get a big spike on Monday 21st afternoon with a 15 ft SSW swell packing a massive 4374 energy! That's serious juice, but the wind is a strong cross-shore, making it a proper washing machine. That's only for the brave or the very experienced. The following days see the swell drop off to the 3-6 ft range, but the wind keeps it bumpy and messy. The very last day, 29th September, shows a weak 4 ft from the E with a short period – not worth getting out of bed for.
So, to break it down: the first three days are a write-off. Your absolute best bet is Thursday 17th afternoon and Friday 18th morning. After that, conditions get tricky, and the end of the run is a slow fizzle. Get on it while the getting is good.
Stay salty,
Rusty

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Thompsons Bay may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
