Table - best surf conditions forecast for Telescopes over the next 16 days.
Alright folks, Rusty here. We’ve got a proper run of groundswell setting into Telescopes over the next couple of weeks. This reef break is exposed to the SW, and the swell’ll be coming in from that sweet spot – mostly SSW, some SW and S later. The water temp’s sitting at 86°, pretty much normal for this time of year with only a tiny anomaly. The combined energy is strong across the board, so expect plenty of push. Right, let’s run through the windows.
The action kicks off Wednesday afternoon (8th July). Swell’s 5 ft from the SSW, a solid 15-second groundswell – long period, which means clean lines and long lulls. Wind’s glassy from the SE at 3 mph, so the surface will be butter. This is proper stuff for experienced surfers; energy’s strong (1198). Crowds can crop up sometimes, but with waves this good you’ll be sharing with a few who know what they’re doing. Thursday morning (9th) it’s a touch smaller at 5 ft, cross-off wind – still clean, but a bit more breeze. The afternoon picks back up to a 4 out of 10 quality.
Friday (10th) morning is clean with a 5 ft SSW swell and a 16-second period – that’s a long groundswell. The cross-off wind’s moderate, but the energy’s still strong (1146). The afternoon builds a touch to 5 ft and the wind drops to a gentle cross-off – another solid session.
Saturday (11th) slows down a bit: 5 ft in the morning, then 4 ft in the afternoon with glassy conditions and a slight air. Still very good, but not standouts.
Now for the highlights. Tuesday 14th July is a beauty: morning sees 4 ft swell with a very long 18-second period – groundswell, dreamy for this reef. Combined energy’s strong (1297), cross-off light breeze, clean. Excellent for experienced surfers. The afternoon keeps the energy up (1212) with 4 ft and 17 seconds, still clean. That’s one of the best windows.
Then, into the second week, the real stunner arrives. Monday 20th July: afternoon sees a 5 ft SSW swell with a 17-second period, combined energy surging to 1721 – that’s powerful. Wind’s glassy from the NW at 3 mph, dead calm. This is top-tier for advanced crew. Tuesday 21st July follows it up with 6 ft, 15-second swell in the morning, glassy calm – energy at 1268. Then the afternoon’s similar, 6 ft and 14 seconds, still glassy. Two days of perfection. Midweek on Wednesday 22nd the swell eases to 5 ft from the S, cross-off – still very good, but the big stuff’s done.
Overall, don’t sleep on the 14th, and definitely clear your schedule for the 20th and 21st if you’re after the best of the run. Consistent, clean, and heaps of energy. Keep an eye on the long-period stuff – it’ll be peeling nicely along the reef, and the lulls give you time to recover. Stay safe out there.

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.
