The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks at Telescopes. This is a solid, consistent reef break that’s exposed to the swell, and it’s gonna be our main focus.
The water temp is sitting at 85° right now, which is bang on average for this time of year, so no surprise there.
Alright, so the first few days are a bit of a write-off. Monday the 3rd through to Thursday the 8th of August, the wave energy is building — we’re talking moderate to strong energy (876 to 2610) — but the wind is all over the place. It’s mostly cross or cross-on, with a lot of risk of thunderstorms, and the wave comment is “marginal.” It’s just not gonna be clean. The swell is coming from the SSW, around 5ft to 7ft, with a long period of 14 to 18 seconds, which is proper groundswell. But with that messy wind, it’s a skip. For a reef, that long period is good, but not with the wind chopping it up.
Now, we start to see a change. Sunday the 9th of August morning is still a bit average with a light cross-shore, but the afternoon is where it gets interesting. The wind swings to the east at just 3 mph, going offshore. The swell is 6ft from the south, with a period of 16 seconds. The energy is strong (1653), and the wave comment is “excellent surf conditions for experienced surfers.” This is the first real standout. It’s a bit on the bigger side, so it’s for the crew who know what they’re doing.
Monday the 10th and Tuesday the 11th keep the quality up with clean, cross-offshore winds from the southeast. The swell stays in the 5ft to 7ft range, still that long-period S to SSW groundswell. The energy is strong to very strong (1732 to 2710). The wind gets a bit stronger on Tuesday the 11th, up to 19 mph, so it’s clean but a bit more challenging. These are still solid days.
We get a bit of a lull in the middle of the week, with clean conditions but the swell drops a little. Wednesday the 14th of August morning and afternoon pick right back up though. The wind is light and cross-offshore, the swell is 6ft to 6ft from the south, period 16 to 17 seconds, and the energy is strong (2164). The comment is “excellent surf conditions for experienced surfers.” That’s another top call.
The real jewel in the crown might be Saturday the 15th and Sunday the 16th of August. Saturday afternoon brings glassy conditions — wind from the SSE at just 3 mph, with a 4ft SSW swell and a 14-second period. The energy is moderate (1077), but it’s glassy. Then Sunday the 16th is glassy all day, with the swell a bit smaller at 4ft to 4ft, but coming from the S and SW with periods up to 16 seconds. The wave comment is “excellent.” For a reef break, glassy conditions with a long-period groundswell? That’s about as good as it gets. The energy is moderate to strong (1159 to 1340), so it’ll have some push.
The last few days, from Monday the 17th into Tuesday the 18th, are still clean and rideable, with the swell dropping a touch to 5ft to 5ft, and the energy fading to moderate (853 to 1419). A solid way to finish the run.
The real standout here is the glassy period from Saturday afternoon, the 15th, through to Sunday, the 16th. That’s the one to circle. The offshore/clean stretch from Sunday the 9th afternoon through to the 14th is also a long, solid run of quality surf. Crowds are listed as “sometimes” at Telescopes, so expect some company, but it’s a reef, so it handles the numbers.
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.
