The Lowdown
Alright, mate, Rusty here. Let’s get into the outlook for Telescopes.
The first week is a bit of a slow burn, but there’s a proper standout waiting for us in the second week. The first few days are dominated by a moderate SSE swell, around 6ft to 4ft, with a period of 10 seconds. The wind is a persistent cross-offshore from the SSE, which keeps the surface clean, but the combined wave energy is only moderate (850 to 494). The water temp is sitting at 86°, which is about average for the time of year. It’s surfable, but nothing to write home about, and the rating is low. There’s a bit of a gap here with no real standout action.
Moving into Monday the 27th and Tuesday the 28th, the swell drops right off to 2ft, but things get interesting. On Tuesday afternoon, the wind goes glassy, and we get a clean 3ft SSE swell. The energy is still low (436), but the calm conditions make it feel like a proper session. Wednesday the 29th is even better – glassy all day, with a 2ft SW groundswell at a juicy 14-second period. The combined energy stays moderate (436 to 492), and the conditions are clean. It’s small, but it would be a lovely, quiet surf.
Now, the real standout. Saturday, the 1st of August, is the one to circle. The morning brings a solid 5ft SSW groundswell with a very long 18-second period. The wind is light and cross-offshore from the SE, keeping it clean. The combined energy jumps to strong (1382). This is a proper reef setup, so that long period is going to produce some well-shaped, powerful lines. It’s rated for advanced surfers, so this is not for the groms. Sunday the 2nd morning is also a beauty – glassy, with a 3ft S swell at a massive 20-second period, and energy of 1272. Conditions will be pristine, but that long period might make it a bit too straight for the beach, though at a reef like Telescopes, it’ll be epic.
The week after that gets messy. From Monday the 3rd, the swell jumps up to 5ft to 6ft, but the wind swings onshore and cross-onshore, and the energy gets very strong (up to 2424). The surf quality drops off with a lot of chop. By Wednesday the 5th, it’s still a bit messy. The second standout is Saturday the 8th of August. The morning brings a 6ft SSW groundswell at 18 seconds, with a clean cross-offshore breeze from the north. The combined energy is very strong at 2486. This is a big, powerful swell, over 8ft, so it’s strictly for experts. The afternoon sees a slight increase to 7ft, but the wind goes light cross-shore, and the rating drops. The morning is the pick.
If you’re looking for the best on offer, it’s Saturday the 1st of August morning for the clean, powerful, long-period groundswell, and Saturday the 8th of August morning for the big, clean, expert-only swell. The first week is for small, glassy sessions, but the big stuff is in the second week.
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.
