The Lowdown
Alright, let’s talk Thompsons Bay. It’s a sheltered spot, so it needs the right push to get going, and for the next 16 days, it’s mostly going to be a patience game. There’s a long stretch of pretty average to poor conditions, but a couple of windows do stand out if you’re willing to wait.
First up, from Thursday 16 July through to Monday 20 July, it’s a bit of a write-off. The swell is small and inconsistent, mostly around 3 to 4 feet from the east, and the wind is onshore or cross-onshore pretty much the whole time. Not worth getting wet for.
Then there’s a gap of a few days with no real recommendations. Tuesday 21 July and Wednesday 22 July are a mixed bag. Wednesday morning the 22nd actually sees a brief moment of calm with glassy conditions and a small 3ft SSW swell, but it’s tiny. The afternoon turns messy again with a strong cross-onshore wind.
Now, the first real standout comes on Thursday 23 July and Friday 24 July. The swell builds from the SSW, reaching 5 to 6 feet, with a period of 14 to 17 seconds – that’s proper groundswell, long and lined up. The energy is moderate to strong. The wind is light cross-onshore, so it’ll be a bit bumpy, but the swell quality will be there. This is best for intermediate surfers; the break is fairly consistent so it should offer some rides. Crowds are sometimes an issue, so keep an eye out. Water temperature is about 71°F, which is about average for this time of year, so no surprises there.
The next big one is Sunday 26 July morning. We’ve got a 5ft SSW swell with a very long period of 18 seconds and strong energy. The wind is a gentle cross-shore, so it’ll be a bit lined up but with a slight chop. This is a proper long-period groundswell, and for a sheltered spot like Thompsons Bay, it might be a bit too straight for the beach, but the reef and points will handle it better. If you’re an expert, this could be the session. It’s a bit of a gamble with the crowds, but the quality is there.
The final week is mostly poor again, with strong onshore winds and lumpy conditions. The morning of 31 July sees a 8ft easterly swell with a short period of 8 seconds and moderate energy. That’s big, but short-period and onshore wind means it’ll be a mess – only for the pros if you’re desperate.
So, if you’re picking, the best bet is the morning of Sunday 26 July for the long-period groundswell, or the Thursday 23 to Friday 24 window for a more consistent, if a little bumpy, session.

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.
