The Lowdown
Alright, let’s get into it. This is Rusty, and here’s the look ahead for Telescopes.
We’ve got a solid run of SSW swell on the cards, but it’s a bit of a mixed bag for the first few days. The water temp is sitting about average for the time of year, nothing too wild there.
Monday kicks things off with a building swell. Monday morning sees a 4ft SSW groundswell, but that cross-off breeze from the SE at 12 mph is keeping it clean enough. The energy is already pumping with a combined energy of 1119 (moderate). By Monday afternoon, the swell jumps to 6ft, same long 16-second period, and the wind eases to a gentle 9 mph. This is looking clean and excellent for experienced surfers. The energy ramps up to 1775 (moderate).
Tuesday morning is the real standout. Glassy conditions with a 5ft SSW swell, 15-second period, and a light SSE breeze of 6 mph. Clean, consistent, and the energy is still strong at 1175 (moderate). This is the best window in the near term. Tuesday afternoon gets a bit cross and messy, so I’d be on it early.
Wednesday morning is a beauty. Absolutely glassy – NNW wind at 0 mph, with a 4ft SSW swell. You can’t ask for better conditions. The energy is moderate at 702. This is a true gem of a morning. Wednesday afternoon sees the wind shift onshore, so it’s a morning-only show.
Thursday brings a new pulse. A very long period 19-second SSW groundswell, 4ft, with a clean cross-off breeze. The energy jumps to 1737 (moderate). This is a groundswell with serious grunt, but with that long period it might be a bit straight at the beach – but Telescopes is a reef, so it should handle it beautifully. It’s a top pick for the experienced crew.
Friday and Saturday see the swell hanging around 5ft to 6ft, but the wind picks up to a moderate 12 mph from the SE, keeping it clean but a bit more challenging. The energy stays moderate (1247 to 712). Sunday drops off a bit, with a smaller 3ft swell and cross winds, creating some chop. Not ideal.
Now, the real fireworks start at the end of the month. Monday, 31 August, through Tuesday, 1 September, is the absolute standout of the entire forecast. Monday afternoon has a 6ft SSW swell, 18-second period, light SSE 6 mph breeze, and a massive energy of 2331 (strong). Tuesday morning is even bigger: 7ft SSW, 17-second period, and an energy of 2773 (strong). This is a serious swell, and it’s clean. This is for advanced surfers only – 7ft is pushing into expert territory. The wind is light and cross-off, so it’ll be a spectacle.
The swells taper off after that. Wednesday, 2 September, still has a solid 6ft, but the wind picks up. After that, we get smaller, less consistent surf through to the end of the first week of September. There’s a notable gap of a few days of marginal surf from 4 September onwards, but by Saturday, 5 September, we get a brief reprieve with a glassy morning, 4ft SSW swell, and calm conditions. That’s a nice little surprise for the weekend.
Overall, the best of the best is Monday afternoon, 31 August, and Tuesday morning, 1 September. Don’t miss the glassy windows on Wednesday, 26 August, and Saturday, 5 September, either. The crowds at Telescopes can be an issue sometimes, so for those top sessions, expect company.
Rusty.

Information about the Telescopes Surf forecast
The above surf forecast table for Telescopes provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Telescopes can be found by selecting the local surf guide option on the grey menu. Our Telescopes 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 (Telescopes) 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 Telescopes 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.
