The Lowdown
G’day, Rusty here, lookin’ at what’s on the cards for Telescopes over the next couple of weeks. And fair dinkum, there’s some proper juice headin’ our way. This is a solid reef break, exposed to the south-west, so when the swell lines up and the wind plays nice, it turns on. We’ve got a bit of a run of clean, quality waves kickin’ off.
Things get goin’ on Wednesday the 26th of August with a nice little pulse. The morning’s glassy, wind is dead calm from the north-northeast, and the swell sits at 4.3 ft from the south-southwest, with a lovely 13-second period. It’s not huge, but the combined energy is a solid moderate 686, and that glassy surface will have it lookin’ like a mirror. Perfect for gettin’ the arms loose. The afternoon stays glassy, swell a touch smaller at 3.9 ft, but still clean as a whistle.
Now, Thursday the 27th of August is where it gets interesting. Bigger swell rolls in, 5.9 ft from the south-southwest, and the period jumps to 18 seconds—that’s proper groundswell energy. The combined energy hits a strong 2045. Morning sees a light south-easterly cross-off breeze, making for clean, lined-up waves. This is advanced territory, though; it’s a reef, and that long-period swell can be powerful.
Friday the 28th keeps the momentum. Another 5.9 ft morning from the south-southwest, but this time with a 16-second period and a light south-easterly cross-off again. The energy is still strong at 1733. It’s clean and hollow. Saturday and Sunday ease off a touch—Saturday the 29th has 4.3 ft morning swell, and Sunday the 30th drops to 3.0 ft, but that Sunday morning has a 21-second period! That’s a proper long-period groundswell, with combined energy of 1282. It’ll be clean with the light south-easterly, but with that sort of period at a reef like this, expect long lulls between sets then some real grinders.
The standout window is Monday the 31st of August right through Wednesday the 2nd of September. Monday morning delivers 5.2 ft, 18-second swell from the south-southwest, combined energy of 1948, and a light south-easterly cross-off. Tuesday the 1st of September pushes it up to 6.2 ft from the south-west with a 16-second period—combined energy is a very strong 2159. Morning is clean with a gentle south-easterly breeze. Wednesday the 2nd holds 5.2 ft, same direction and period, clean again with light wind. This is the heart of the run. The water temp is about average for this time of year.
After that, things mellow out through the first week of September. Swell sizes drop to around 4.3 ft to 2.6 ft, but there are still clean windows. Sunday the 6th of September sees a return of 3.9 ft, 15-second swell with light wind. But then get this—Wednesday the 9th of September, a week-and-a-bit out, we get a bloody ripper. Morning sees 4.6 ft from the south, but with a 21-second period and combined energy of 3566—that is very, very strong for that size. It’s a clean, light south-easterly morning. Thursday the 10th keeps it going with 5.6 ft, 16-second swell and 1976 energy, again almost glassy. That Wednesday the 9th is the one to circle on the calendar, but it’s a long way out so keep an eye on it.
Crowds are possible here—it’s a known spot that can get busy on the good days. But when it’s this clean and this consistent, a bit of company is a small price to pay.

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.
