The Lowdown
G'day, Rusty here. Let's get stuck into what's on the cards for Telescopes. It's looking like a solid stretch of surf, so if you've been waiting for a proper run, this could be your window.
The water's sitting at about 85°, which is a touch warmer than the long-term average for this time of year—not a big deal, but a little more tropical than usual. The start of the period isn't perfect. We've got a long-period SSW groundswell with 16-17 second intervals, which is great for power, but Friday afternoon will have a bit of cross-on wind and some chop. Wave heights are around 7ft, and the wave energy is strong, with values like 2814 showing it has some punch.
Saturday morning, though, is where it turns on. The wind goes light easterly and glassy, and with 7ft of SSW swell at 16 seconds, it will be clean as a whistle. The energy is strong at 2174, and this swell direction is exactly what Telescopes wants. This is for the experienced crew—it's a proper reef wave.
There's a bit of a mixed bag on Sunday and Monday with more wind, but the surf stays in the 5ft to 7ft range. Then, keep your eyes on Tuesday morning. The swell is back up to 7ft, but the energy jumps to a hefty 3287. The wind is light and cross-off, leaving the faces perfect. That's going to be a cracker.
The rest of the week holds plenty of clean surf between 5ft and 8ft with light winds. It's consistent. Then, for the second week, the real standout is on the 19th and 20th of August. Wednesday the 19th has 8ft of SSW swell with a massive 4239 energy reading, and it's clean. But Thursday the 20th, that's the big one. 8ft of SSW swell, a long 17-second period, and a huge 3426 to 3216 energy, with the wind going glassy in the afternoon. This is a special day for experts only—powerful and perfect. It's still over a week away, so it's promising but we'll have to see how it firms up.
There's a bit of a lull in the middle of that second week, but the run into the 22nd looks fun with clean waves in the 5ft to 6ft range to finish things off. All in all, there's plenty to get excited about. Just know your limits, as this spot can handle some serious size.
Rusty out.

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.
