The Lowdown
Alright, let’s break it down. For the next couple of weeks at Telescopes, it’s gonna be a slow burn at first. This is an exposed reef break, consistent and for advanced surfers. Water temp is about 84°F, pretty normal for this time of year.
From Wednesday the 16th through the end of the following week, it’s mostly marginal. Swell runs from about 4ft to 6ft, out of the SSW, with moderate winds keeping things choppy. The energy’s moderate, like on Thursday the 17th morning we saw about 1020 units, but the wind’s not dialed and the surf quality is just okay. Nothing to get too excited about.
Monday the 21st morning is the first real bright spot. We’ve got a 6ft SSW swell, 14-second period, light SE wind making it cross-off and clean. Energy is strong (1176) and it’s rated excellent for experienced folks. Then Monday afternoon goes glassy—wind drops to 3 mph from the SSE, still 5ft SSW swell—that’s a beauty. That’s your best window in the first week.
Now, fast forward to Saturday the 26th and Sunday the 27th. This is the big one. Saturday morning shows a 7ft SSW swell with a 20-second period—that’s serious long-period groundswell, and the energy is massive (3995). This is for experts only. Wind is cross-off and clean, so the reef will be holding up well. Saturday afternoon hits 8ft, and Sunday holds at 8ft with a 17-second period. Sunday afternoon gets the best rating of the whole run: 8ft, light cross-off wind (6 mph), and it’s marked excellent for experienced surfers. The energy is still enormous (3584). That Sunday afternoon is the real standout—big, clean, and heavy. Don’t even think about it if you’re not solid.
After that, Monday the 28th and Tuesday the 29th drop back to 7ft and 6ft, still clean but not the highlight. Then into October, Thursday the 1st morning has a 3ft swell but with a 20-second period and clean offshore wind—there’s quality in the shape if you’ve got a bigger board.
First few days? Pass. The real call is Monday the 21st for a clean, fun session, and then the big, expert-only groundswell Saturday the 26th into Sunday the 27th. That Sunday afternoon is the pick of the whole lot.

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.
