The Lowdown

Alright folks, Rusty here with the long-range picture. We’ve got a bit of a slow start, but there’s a few days of decent waves if you know when to look.

The first few days are basically a washout. The wind is all over the place, mostly cross and onshore, and the swell is short-period and junky. You’d be wasting your time paddling out. We’re looking at a few days of this, maybe four or five, before things start to clean up.

The real turning point is Sunday the 16th. The wind goes glassy in the morning, and we’ve got a 2.0m swell rolling in from the E with a 10-second period. The energy is moderate (826), but the clean conditions make it feel a lot better. This is the day to be out there. Water temp is 71°, which is pretty standard for this time of year, so you won’t need a hood.

Monday the 17th keeps the size up, with 2.2m from the E and a longer 11-second period. The energy is a bit stronger (1166), but the wind swings to a cross-shore, putting a bit of chop on the face. It’s still good, but Sunday is the cleaner of the two.

After that, it slowly fades. We get another glassy spell on Tuesday afternoon the 18th, with 1.8m waves, but it’s not the same quality. The second week is mostly small and wind-affected. The swell drops below a metre by the 21st, and the last few days are just not worth the paddle. There’s a small pulse from the S on the 23rd, but it’s tiny and onshore—not a goer.

So, mark your calendar for the morning of Sunday the 16th. That’s the pick of the fortnight. The E swell at 2.0m should be clean and lined-up, thanks to the glassy conditions. It’s a fairly consistent break, so you should get some waves, but it can get a little crowded, so be prepared to share. It’s an intermediate wave, so some push to it, but nothing scary. If you’re just starting out, that size might be a bit much, so maybe sit this one out.

The second-week stuff is more of a lottery. The models aren’t showing much, and the wind is iffy. I’d keep my expectations low for that far out.

That’s the skinny. A few rough days, then a window of clean surf. Be ready for it, because it doesn’t hang around.

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.
