The Lowdown
Alright folks, it's Rusty here. Let's have a look at what's cookin' for this next stretch. It's a bit of a slow start, but hold onto your boards, because the second half of this outlook is where the magic is shaping up.
We're looking at a solid run of cleaner, glassy conditions, especially in the mornings, which is a real treat. The water's sitting at a warm 86°, which is a touch above average but nothing too wild for the time of year. The main draw is the promise of some serious, long-period groundswell coming in the second week, and for a spot like Telescopes, a reef break, that's music to my ears. The swell direction is lining up beautifully from the SSW, which is exactly what this break wants to see.
The first few days are a bit of a mixed bag. Starting Sunday the 26th, we've got a 5ft swell from the SSE, but the cross-off wind, combined with a moderate breeze, makes it a bit of a messy affair. The combined energy is moderate at 541. Not the day to write home about. Monday and Tuesday are similar, with cleaner mornings but smaller, weaker swells coming in around 2ft to 4ft.
Now, the real spark comes in on Thursday the 30th. The morning session is a beauty. We’ve got a 3ft swell from the SSW, but the period is a whopping 19 seconds, and the energy has jumped to 978. The wind is a gentle cross-off breeze, keeping it clean. That's some proper groundswell, and it's going to wrap into that reef with some serious power.
The standout of the whole forecast, though, is Saturday the 1st of August. You've got a morning session that is pure glass. Zero wind, it's dead calm. This is a "risk tstorm" day, but while the surf's up, the conditions will be pristine. The swell is a solid 5ft from the SSW with a 17-second period, and the energy is a strong 1142. This is absolutely prime time for Telescopes. The afternoon stays glassy too, with a west wind swinging in light. This is the one to circle on the calendar.
Sunday the 2nd is another glassy morning, with a 3ft swell from the S, but the period is even longer at 19 seconds, and the energy is a beastly 1174. It's a bit smaller, but that long period will make it wall up perfectly on the reef.
The following week continues to offer up some excellent sessions. Monday the 3rd afternoon goes glassy again with a 4ft SSW swell, and Tuesday the 4th, both morning and afternoon, are glassy with a solid 5ft SSW swell. The energy is hovering around the 1000 mark, so the ocean is well and truly awake.
The real finale kicks off on Saturday the 8th of August. The morning is glassy, with a 5ft S swell and an 18-second period. The energy is a massive 2303, which is strong to very strong. The afternoon is just as good, with a 6ft SSW swell and the same energy levels. This is serious, powerful groundswell. For Telescopes, this is a dream setup.
Sunday the 9th sees the swell size bump up to 7ft to 7ft. The energy is even higher at 2651, but the wind picks up to a moderate cross-off. This is getting into the "experts only" territory for sure, but the quality is still there.
Monday the 10th, the final day in the window, is also a cracker. The morning has a 7ft S swell, and the afternoon bumps it up to 6ft, both with a 14-second period and massive energy levels (1713 and 2814). The wind is a gentle cross-off, keeping it clean.
So, the true standouts are the morning of Saturday the 1st of August and the morning of Saturday the 8th of August. The first is a glassy, perfect condition day with a solid, long-period swell. The second is a bigger, more powerful groundswell that will have the reef absolutely pumping. The long-range stuff for the 8th and 9th is a bit further out, so it's a promising forecast, but always subject to change. Still, it's looking like a ripper of a run.
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.
