The Lowdown
Right, let’s have a look at what’s on the cards. It’s a bit of a slow burner to start, but there’s some proper juice in the back half of this forecast window, so don’t go putting the board away just yet.
We’re looking at a stretch that starts off with a bit of a whimper. For the first few days, the swell is there but it’s pretty average. Wednesday the 2nd and Thursday the 3rd have some waist-high lines, but the cross-off winds keep things from being a total write-off. It’s clean enough, but it’s not going to get the heart rate up. The energy is weak, registering around 1619 on Wednesday morning, dropping to the 500s by Friday. It’s just a bit of a grovel, honestly.
Things start to shift a little from the 8th onwards. We see the period stretch out and the energy climb back into the four digits. The light winds make for some clean sessions, but it’s still a bit underwhelming. There’s a bump on the 12th and 13th where the swell kicks up to 6ft and 7ft, and the energy is strong, around 2076 to 3107. That’s more like it. The Saturday morning of the 12th is glassy and clean, and that Sunday morning the 13th is the standout of the first week. It’s a proper push of SSW swell at 7ft with a 17-second period, and the water is flat as a tack. That’s the one to circle if you’ve got the skills. It’s a big, powerful reef, so this is strictly for the experienced crew.
The real story, though, is that run in the second week. After a bit of a lull on the 14th and 15th, it just switches on. The 16th and 17th of September look like the best of the lot. We’re seeing 7ft of SSW groundswell with a 16-second period, and the energy is right up there at 2432. The winds are light and offshore in the mornings, making for some absolutely perfect conditions at Telescopes (Telescopes). This is a consistent, exposed reef that handles this SW direction perfectly. It’s going to be big, powerful, and lined up. This is the one to plan for. It’s a week out, so don’t book the plane ticket just yet, but it’s looking very, very promising.
The water temp is sitting at 85°, which is about 1° warmer than the norm for this time of year. Nothing crazy, just a touch on the warm side. And with the crowds often out at a spot like this, you’ll want to be there early for the dawny.
So, there you have it. A bit of a slow start, but that window from the 16th to the 17th is the one. Keep an eye on that forecast, because if it holds, it’s going to be special.

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.
