The Lowdown
Alright, let’s talk Telescopes. Only break in the 16-day window, and it’s a reef slab that’s got some serious juice coming through. This is advanced territory – beginners need to sit this one out.
Water temp is 30° – that’s about 0.8° warmer than usual, so nothing wild, just a bit of a warm bath.
We start on Sunday the 30th of August. Morning has a 0.9m SSW swell with a 21-second period – that’s a very long period groundswell. The combined energy is 1068 (moderate), with SSE wind at 15 km/h, cross-off. Clean, lined-up reef waves. Afternoon bumps to 1.0m but the wind goes cross and energy hits 1232, though the tide might be tricky. Sunday morning is a standout: glassy, clean, and that deep ocean swell will have the reef working.
Monday the 31st: swell builds. Morning 1.6m, 18 seconds, 1965 energy (strong), wind SSE 20 km/h cross-off – clean. Afternoon 1.9m, 18 seconds, 2435 energy. At 1.9m, this is expert-only. The reef is pumping, but the wind keeps it from being perfect.
Tuesday the 1st of September: morning peak at 2.1m, SW swell, 17 seconds, 2568 energy. Clean cross-off wind. Big, powerful, but only for the experienced. Afternoon drops off with cross chop.
Wednesday the 2nd: eases to 1.7m, 16 seconds, 1598 energy, clean cross-off. Excellent conditions. Afternoon fades.
Thursday the 3rd: magic morning. 1.4m, 15 seconds, 884 energy, and glassy – SSE wind 5 km/h, glass. Clean, smooth, lined-up reef. Afternoon is cross-off and clean. This is a standout: that glassy morning will have Telescopes feeling like a private wave.
Friday the 4th and Saturday the 5th: swell drops to 0.7m to 1.2m, wind up. Skip it.
Sunday the 6th and Monday the 7th: recover to 1.2m to 1.6m, but wind is up and period drops. Monday afternoon has a short 8-second swell – messy.
Tuesday the 8th of September: new pulse. 1.4m, 18 seconds, 1686 energy, light SE wind cross-off. Clean, excellent. Afternoon cross-on from the SW. Stick to the morning.
Wednesday the 9th: the big standout. Morning: 1.9m, 15 seconds, 2072 energy, glassy – N wind 5 km/h, glass. Afternoon: 1.7m, 15 seconds, 1713 energy, glassy again. Two sessions of clean, glassy, powerful groundswell. This is the best of the forecast. If you can only surf one day, this is it.
Thursday the 10th: still good in the morning – 1.7m, 16 seconds, 1488 energy, clean. Afternoon fades.
Friday the 11th: morning lull, but afternoon picks up with 1.6m, 18 seconds, 1731 energy, and gentle cross-off wind. Excellent session.
Weekend of the 12th and 13th: swell builds again. Saturday 1.7m to 1.6m, moderate wind. Sunday the 13th: 2.1m morning, 2.2m afternoon, 18 and 17 seconds, energy over 2700 (strong to very strong), wind SE to SSE 25 km/h cross-off. Heavy, powerful – expert only, and the wind keeps it from being glassy. Still, for the adrenaline crew, it’s a go.
Monday the 14th of September: close out with 1.8m, 16 seconds, 1570 energy, light cross-off wind – excellent conditions.
Best bets: Sunday 30th morning, Thursday 3rd morning, Wednesday 9th all day, Friday 11th afternoon. The absolute standout is Wednesday the 9th – glassy, powerful, and clean. Get after it.

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.
