The Lowdown
Right on, Rusty here, and I've got the scoop on what's coming down the line.
Alright, we're looking at a pretty solid run for Telescopes. Things kick off a bit rough, but once we get past the first few days, it cleans right up into a real nice stretch. The swell's coming from the south-southwest, which is exactly what this spot wants.
The water temp feels about average for the time of year, nothing wild there.
So, Thursday the 6th and Friday the 7th are a bit of a write-off, honestly. There's swell in the water – around 4.9ft to 7.2ft with a long period – but the wind is all over the place and it's messy. The energy's there, but the conditions are marginal with a cross-chop. You'd be fighting it. But then, the real window starts.
Saturday the 8th is when it turns. We've got a 6.9ft swell from the SSW with a 16-second period, and the wind goes light and cross-offshore. That's the ticket. The energy is still strong (2202) and it's going to be clean. That morning session looks like the standout. Sunday the 9th keeps the goods coming, a bit smaller at 6.2ft but still clean with a light cross-off. Monday the 10th is another beauty – a long period S swell (22 seconds!) at 3.9ft in the morning and 5.2ft in the arvo. The energy numbers are through the roof for that size (2588 and 2739). That long period and S direction will be hitting this reef perfectly, offering up some real powerful, lined-up waves.
Tuesday the 11th pushes up to 7.2ft but the wind stays clean. It's a bit bigger, so it'll be for the experienced crew, but the conditions are there. We do have a bit of a lull around the 17th where the size drops and the wind gets a bit messy again on the 17th afternoon, but it bounces right back.
If I had to pick the absolute best, it's a toss-up between Saturday the 8th morning and Monday the 10th. For pure, clean power, Saturday gets the nod. That light offshore wind and solid 6.9ft SSW swell is going to be prime. It's consistent, the direction is spot on, and we're talking clean conditions for experienced surfers. Keep an eye on the long-period groundswell on Monday too – that S swell at 22 seconds will be offering some proper juice, but it might wrap a little differently. For the best combination of solid size and glassy conditions, Saturday the 8th morning is your session. It can get a crowd in there sometimes, so get in early.
Get 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.
