The Lowdown
Hey, Rusty here. Let’s talk about what’s shaping up. One break is in the picture, and it’s a reef that knows how to handle a proper swell.
We’re looking at Telescopes—an advanced reef break that’s exposed to the SW. Water temp is 85°F, which is 1°F warmer than average—pretty much normal for this time of year. Nothing unusual there.
Saturday the 5th and Sunday the 6th are clean, but the swell is just getting going. Saturday morning has a 4ft SSW swell at 14 seconds with moderate energy (503), but with a 25 km/h cross-off wind, it’s a bit marginal. Not the best way to start.
The first real green light is Tuesday the 8th afternoon. Swell rises to 4ft from the SSW, period hits a groundswell 17 seconds, and energy jumps to 1400. Wind drops to a gentle 15 km/h cross-off, so it’s clean. Excellent for advanced surfers.
From Wednesday the 9th morning through Thursday the 10th afternoon, we’ve got a solid run. Swell sits around 5ft to 5ft, periods 15 to 17 seconds, and energy in the strong range (1176 to 1435). Winds stay light and cross-off. The standout here is Thursday the 10th morning—1.5m (5ft) SSW at 16 seconds, clean, energy at 1405. That’s the pick of the first week.
Friday the 11th holds at 5ft SSW, clean, strong energy. Then Saturday the 12th afternoon brings 5ft SW at 19 seconds, energy surging to 2415. That’s a long-period groundswell that’ll wrap perfectly into this reef. Crowds are “sometimes,” so you might have company, but it’s worth it.
The big highlight hits Sunday the 13th morning. Swell runs 7ft SW at 17 seconds, combined energy at a beefy 2514. That’s expert territory—big, powerful, and clean with a light cross-off. Best of the whole outlook, but it’s about a week and a half away, so watch the forecast.
After that, it eases but stays good. Monday the 14th and Tuesday the 15th give 5ft to 6ft SSW, clean in the mornings. Thursday the 17th morning features a 4ft SSW swell at a very long 18 seconds—clean, lined-up, but with long lulls.
Into the second week, Friday the 18th and Saturday the 19th keep 6ft SSW swell, but wind picks up to 20–25 km/h in the afternoons. Still clean mornings. Sunday the 20th morning has a 7ft SSW swell with moderate energy (1960) and cross-off wind—a solid last session.
No real gaps here—Telescopes is consistent and has surf the whole 16 days. The true standouts are Thursday the 10th for the quality combo and Sunday the 13th for the biggest, most powerful swell. That Sunday is the one to circle.
Rusty out.

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.
