Alright, Rusty here. Let’s break down Thompsons Bay for the next couple of weeks. We’ve got a slow, messy start, but there are a few moments that might get you interested.
First few days are totally flat or junk. Tiny swell, wrong wind. The first real date to look at is Friday, July 10th. The morning brings a 7ft south swell, but the wind is cross-onshore, and the ocean has a strong 1915 units of energy. By the afternoon, it’s jumping to 8ft from the south with a 16-second period and energy at 3061. That’s a serious groundswell, very long period. This is big, expert-only territory – way too much for a beginner, and with that wind, it’s going to be a rough one.
Saturday, July 11th still has size – around 6ft in the morning and 5ft in the afternoon – but the wind stays onshore or cross-on. The conditions are only marginal.
The best looking window is Wednesday, July 15th in the morning. We’ve got a 5ft south swell with a 10-second period and a light cross-offshore breeze from the NNE. The ocean has moderate energy at 885, and the report says “clean” with good surf conditions. For Thompsons Bay, which is fairly consistent but sheltered and really needs a NW wind to be perfect, this is the only time things line up. Water temp is normal for the season. It’s the standout, but it’s more of a tidy, fun wave for intermediates than a heavy one.
After that, it’s a long stretch of poor conditions from Thursday the 16th right through to the 22nd of July. Strong winds, chop, and no real quality. There’s a brief glassy moment on Saturday, July 18th in the afternoon with a 2ft south swell, but it’s only very ordinary.
Bottom line: your best shot is the morning of July 15th. It’s not going to blow your mind, but it’s the cleanest we get.
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.
