The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Telescopes.
We’ve got a solid run of surf coming our way, but it’s a slow start. The first few days are a bit of a write-off, with the wind messing things up and the conditions not quite coming together. But hold on, because from Tuesday the 25th of August, things start to get interesting and it builds into a really good stretch.
The standout period is from Tuesday the 25th of August through to the start of September. That’s where the real juice is. We’ve got a consistent SSW groundswell arriving, with periods well over 15 seconds, meaning long, powerful lines. The combined energy is strong, hitting up to 2647, so there’s plenty of grunt in the water. This is a heavy, exposed reef break, so that long-period swell will wrap in beautifully, offering some proper, deep-water barrels. The size hangs around 5 ft to 7 ft, so it’s one for the advanced crew – beginners, give this one a miss when it’s over 5 ft.
The best of the best looks like Thursday morning the 27th of August. Glassy conditions, zero wind, a 4 ft swell from the SSW with a super-long 19-second period, and energy at 1734. It’s going to be pristine, clean, and offering some of the best waves of the whole run. The morning of the 1st of September is also a contender, with a clean 7 ft SW swell and energy at 2647, but that’s pushing into big, powerful territory.
Crowds are possible here, so get in early on those glassy mornings. The water temperature is about average for this time of year, nothing too unusual. The wind is mostly cross-offshore or light, which is what you want on a reef, keeping the faces clean.
After the 1st of September, the swell slowly backs off, but it stays fun and clean through the 4th, with smaller waves in the 3 ft range. The last few days of the forecast, from the 5th of September, the wind picks up and the quality drops, so it’s more of a marginal call.
So, set your alarm for the morning of the 27th of August. That’s the one to circle.
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.
