The Lowdown
Alright, so we’re looking at just the one spot for the next 16 days: Telescopes. It’s a reef break that loves a good SW groundswell. We’ve got waves coming through, but not every session is a winner.
The action starts Friday afternoon, 21 August, but that first one is sloppy – storm risk and a cross-shore wind means it’s not worth rushing out for.
Your first real highlight is Saturday morning, 22 August. Clean conditions with a cross-off breeze, 2.2m SSW groundswell, 16-second period. That’s solid energy (2261) and the reef will love that long period.
Sunday 23rd through Tuesday morning 25th keep the swell rolling. Tuesday morning the 25th is clean, light breeze, 1.8m SSW. That’s a good session for experienced surfers.
The swell dips a little midweek, but Thursday afternoon 27 August is a standout. The period jumps to 18 seconds, wave height 1.3m SSW, clean offshore breeze. That’s a long, powerful groundswell for the reef – energy at 1549 packs a punch for the size.
Friday morning 28 August bumps back up to 1.9m, clean again. Good energy.
The absolute best comes at the start of September. The afternoon of Monday 31 August is glassy – 1.7m SSW, 18-second period, no wind. Then Tuesday 1 September morning and afternoon is the top of the heap. You get 2.2m SW groundswell with an 18-second period, energy readings of 3144 and 3032, and glassy or light offshore wind. That’s expert-level surf, powerful and clean as it gets.
After that, things ease off into smaller clean waves through the 4th and 5th September.
Water temp is around 29° – normal for this time of year, nice and warm.
Crowds can be around at Telescopes sometimes, especially on those glassy days. But the reef handles it.
Forget the first Friday. Your sessions to circle are Tuesday 25th morning, Thursday 27th afternoon, and the absolute winner: Tuesday 1st September.

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.
