The Lowdown
Alright, Rusty here. Let's have a look at what's coming down the line for us.
Alright, Thompsons Bay, it's a fairly consistent spot, but honestly, this stretch ain't looking too flash for a while. The first real glimmer of something decent is a long way off, so we've got a big gap of quiet days to get through first.
The early part of the run, from Thursday the 16th through to the end of the weekend, is pretty much a write-off. We've got some swell around, a bit of energy from the east with readings around 5 ft Thursday morning, but the wind is straight onshore from the SE. That's going to wreck it. It stays messy and cross-onshore or cross-shore through the weekend, with the swell dropping off. The 19th sees a bit of a pulse from the south, with combined energy of 927, but it's blown out by a moderate cross-onshore breeze. Not worth paddling out for.
The week after that, from Monday the 20th through to Thursday the 24th, is just more of the same story. The wind is all over the shop, mostly cross or cross-onshore, keeping the surface choppy and lumpy. There's a bit of groundswell trying to push through, but the conditions just aren't there to make it user-friendly. You'd be fighting a losing battle.
Now, the standout. Mark your calendar for Tuesday the 21st. That morning, it’s going to be glassy. Absolutely dead calm with a NNE breeze at just 3 mph. The swell will be a small 3 ft from the SSE, but with that glassy surface, the wave quality will be the best we see in this whole period. It's a sheltered spot, so with the wind off, it'll be pristine. The combined energy is a moderate 420, and the period is a solid 11 seconds, so it's a proper groundswell that’ll have some shape. It won't be big, but it will be the cleanest wave in the bay. An intermediate-friendly size and likely the only real window of quality.
Late in the month, we get another chance on Saturday the 25th. Another glassy morning, with a tiny 3 ft south swell pushing in. The combined energy is 385. It's surfable, but very ordinary. And then the very end of the run, on Wednesday the 29th, the afternoon session is looking glassy again with a 2 ft south swell. Again, small, but clean.
So, the bottom line is this: the whole 16-day window is a waiting game. The one and only true standout is the morning of Tuesday the 21st. Get out there for the glassy conditions, because before that and after that, it's mostly a lot of wind-affected, poor-quality surf. The water temp is about average for the time of year, so nothing crazy to report there.
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.

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.
