The Lowdown
Alright, this is Rusty, and I’m lookin’ at the next few weeks for Telescopes. And let me tell ya, this stretch has got some serious potential. We’re talkin’ a consistent run of clean, lined-up SSW groundswell, with a few days that are gonna be absolutely firing.
We kick things off on Tuesday the 28th of July. It’s a bit of a slow start with a small 2ft swell from the SSW, but the water’s a warm 85°, which is spot on for this time of year. The real story is that this is just the beginning. By Wednesday the 29th, the swell is already nudging up to 3ft, and the wind is a clean cross-off. The energy is building, with moderate energy levels around (596), and the waves are looking clean. This is a nice, gentle start.
Then Thursday the 30th, the magic starts to happen. The swell jumps to 3ft, but the period stretches out to a very long 19 seconds. That’s proper groundswell energy (938), and with that cross-off wind, the waves are gonna be holding up beautifully. This is a standout for the first week.
Friday the 31st of July is our first real highlight. We’ve got a 5ft SSW swell, with a 16-second period, and the wind is clean cross-off. The energy is strong at (1171), and the wave comment is calling it excellent for experienced surfers. This is gettin’ into the territory where beginners might wanna sit this one out, but for anyone with a bit of paddle fitness, it’s gonna be a ripper.
Saturday the 1st of August, the swell drops slightly to 5ft, but the period is still a long 17 seconds. The wind goes super light, almost glassy. The energy is pumping at (1202). This is another top-tier morning. The tide might be a factor in the afternoon, but the morning session is a must.
Sunday the 2nd of August into Monday the 3rd, the swell stays in the 3ft to 5ft range, but the wind stays clean and cross-off. There’s a risk of thunderstorms, but that’s a small price to pay for clean waves. The energy is strong (1056 to 861), and the wave quality is very good.
Now, Tuesday the 4th of August. This is a sleeper. The swell is 5ft, but the wind goes glassy from the NNW in the morning. I mean, dead flat calm. The energy is strong (1102), and the waves are gonna be perfect. This is a true standout, just for the conditions alone. The afternoon gets a bit bumpy with a cross-on wind, but that morning window is gold.
Wednesday the 5th of August is another glassy morning, with the same 5ft SSW swell and strong energy (1517). This is a dream run. The afternoon gets a bit of a blow from the NNE, but those morning sessions are the ones to circle.
The second week gets a bit more interesting. From Thursday the 6th to Saturday the 8th of August, the swell builds to 6ft to 7ft, and the energy gets very strong (1801 to 2998). This is big, powerful swell. The problem is the wind goes cross and cross-on, making it choppy. This is more of a kite-surfing setup than a clean paddle session. The waves are there, but the quality is messy. This is a gap in the good surf.
Then, on Sunday the 9th of August, the wind swings back to the SE, clean and cross-off. The swell is a solid 7ft from the S, with a 16-second period and very strong energy (2172). This is another big-wave day for experienced surfers only. The conditions are clean, and the waves will be holding up.
Monday the 10th and Tuesday the 11th of August, the swell drops to 4ft to 5ft, and the wind stays clean cross-off. The energy is still strong (1192 to 2023). The waves are there, but the quality is marginal. Still, a clean 5ft wave is better than no wave.
Wednesday the 12th of August wraps it up with a 6ft swell from the S, clean cross-off wind, and moderate energy (1687). It’s not the cleanest of the run, but it’s a solid end to the forecast.
So, what’s the pick? The absolute best on offer is the morning of Tuesday the 4th of August for the glassy conditions and that perfect, clean 5ft SSW swell. For a bigger, more powerful session, the mornings of Friday the 31st of July and Sunday the 9th of August are your standouts. The crowds might pop up here and there, but with quality like this, it’s worth sharing.
Stay stoked.

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.
