The Lowdown
Alright folks, Rusty here. Let’s talk about the next couple of weeks at Telescopes. This stretch is a ripper for the experienced crew, with a sustained run of quality SSW groundswell and generally clean conditions. Don’t let the risk of a thunderstorm put you off; the wind is the real story here.
We kick off with a solid pulse on Thursday the 27th of August. The morning is a standout for the advanced crew. We’ve got a clean 4ft SSW groundswell rolling in with a very long 19-second period. That’s proper groundswell energy, and the combined energy is a hefty 1724 (moderate to strong). The wind is a light, cross-offshore breeze from the SE, keeping the faces smooth. This is prime reef-surfing territory. The afternoon sees the swell jump to 6ft, but the wind shifts a little cross-shore, making it a bit less perfect. Still, the energy is up to 2045.
Friday the 28th is another beauty. The morning session is clean again with a light SE cross-off breeze and 6ft of SSW swell at 16 seconds. This is powerful, consistent stuff with a combined energy of 1724. The afternoon sees the swell drop a touch to 6ft, and the wind picks up to a gentle breeze, but it’s still cross-off, so it’s manageable.
Saturday the 29th is a step down. The swell backs off to 4ft with a shorter 14-second period, and the moderate breeze makes it feel a bit more messy. The energy drops to 749. Not a write-off, but the earlier days are much better.
We get a bit of a lull on Sunday the 30th with smaller swell, but then a new pulse hits on Monday the 31st. The morning brings back 5ft of SSW swell at 18 seconds and a combined energy of 2022. The wind is a gentle cross-off breeze. Afternoon bumps it to 6ft from the SW, edging the energy up to 2211. This is excellent.
The real standout of the whole period is Tuesday the 1st of September. Morning delivers a solid 7ft of SW swell with a 17-second period, and the combined energy is a powerful 2557. The wind is a gentle cross-off again. This is pushing into expert-only territory at over 8ft during the peak, but it’s a serious, powerful slab. The afternoon holds at 7ft with a light breeze. This is the best on offer.
The swell slowly winds down through the first week of September, but it stays surfable. The conditions are still cross-off and clean. A real treat comes on Thursday the 3rd of September. The swell is a smaller 4ft from the SW, but the wind goes glassy offshore in the morning with a slight air, and then the afternoon is pure glass. Combined energy is 690. It’s a beautiful, mellow window for the experienced surfer who wants clean lines.
Friday the 4th of September is another glassy morning with a tiny 5ft SSW swell, but the wind is dead calm (0 mph). It’s as clean as it gets with a combined energy of 698. The afternoon turns cross-shore and bumpy, so get your session in early.
The second week settles into a more relaxed pattern. Swell drops to around 3ft to 4ft, but the conditions remain mostly clean or light cross-off. The week of the 7th to the 10th of September has some nice glassy mornings, especially on the 8th and 9th, with small but clean waves. The 10th of September sees a pickup in energy to 1073 with a nice 4ft, 16-second SSW swell and a light breeze. The 11th of September finishes the outlook with another clean, 4ft morning.
The water temperature is about average for the time of year, nothing unusual to report. Crowds are possible at Telescopes, given the quality on offer, but the size and advanced nature of the waves will thin the pack out a bit. If you’re not an expert, give the bigger days a miss.
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.
