The Lowdown
Imperial Version
Alright, Rusty here. Let’s be honest, Thompsons Bay – it’s a sheltered spot, and the next two weeks look like a real mixed bag. We’re not exactly blessed with classic conditions, but there are a few windows where it could get fun. The water's sitting at about 68°, which is a bit cooler than normal for this time of year, so you might want a spring suit.
The first few days are a write-off. Tuesday and Wednesday are just not happening – poor surf, messy winds, and the water’s a bit chilly. It’s a tough start.
We get a bit of a tease on Thursday the 3rd. The morning shows a small 2ft swell from the SSW (14 sec period) with clean conditions and a light offshore breeze. The wave energy is moderate (412). It’s a marginal call, but if you’re desperate, that’s your best bet early on.
Then Friday the 4th through Sunday the 6th is a total mess. Strong winds, rain, and a big lumpy swell that’s way too big for the quality of the wind. Friday afternoon sees a 13ft swell from the south with a fresh cross-onshore. That’s expert-only territory, if it’s even surfable. Honestly, that setup looks more interesting for kite surfing than paddle surfing.
Now, the real standout comes on Monday the 7th. We’ve got a solid 13ft groundswell from the south with a very long period of 17 seconds. The energy is pumping (8710). The morning has a gentle cross-shore and it’s a marginal call, but the afternoon cleans up nicely with a cross-off breeze from the NE. This is a big, powerful swell. For a sheltered spot like Thompsons Bay, this long-period groundswell from the south could wrap in beautifully. It’s big enough for experts only, but if you’ve got the skills, this is the best session on offer. Just be aware, it’s a long-range call, so the forecast could shift.
The next week is a bit of a letdown. We get a tiny window on Saturday the 12th afternoon. The swell is 7ft from the ENE (8 sec) and the conditions go glassy. That’s a rare moment of pure calm, and the energy is moderate (624). It’s not the biggest, but with zero wind, it’ll be clean. That’s your best bet for a fun, manageable session.
The rest of the second week is just more of the same: messy winds, lumpy conditions, and poor surf. Nothing really stands out.
So, to sum it up: the highlight is Monday the 7th for the big, powerful groundswell, but only for the experts. For a more relaxed session, keep an eye on Saturday the 12th afternoon for the glassy conditions. Otherwise, it’s a pretty quiet outlook.
Rusty.

Information about the Thompsons Bay Surf forecast
The above surf forecast table for Thompsons Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Thompsons Bay can be found by selecting the local surf guide option on the grey menu. Our Thompsons Bay surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Thompsons Bay) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
