The Lowdown

Alright folks, Rusty here. Let’s talk about what’s cooking at Telescopes.

First up, this is a solid reef break that’s exposed to the swell and consistent. It’s an advanced wave, so you need to bring your A-game. The water temp is about average for this time of year, nothing wild there.

The outlook starts with a bit of a dampener. From Tuesday the 21st right through until the morning of Sunday the 26th, we’ve got marginal conditions. The swell is there, running 4ft to 6ft from the SSW to SSE, but the wind is a persistent cross-off from the SE, and there’s a lot of risk of thunderstorms. The energy is moderate, sitting around 419 to 953 (combined energy), but the whole setup feels a bit messy. You’ll be fighting the wind and the chop.

Then Sunday the 26th afternoon brings a shift. The wind swings to a light S cross-shore, and the swell drops to 4ft from the SSE. The energy is still moderate at 500, but the lighter wind gives you a cleaner canvas. Still, the tide or conditions keep it marginal.

The real standout starts to build on Monday the 27th. We’ve got a clean morning with a light offshore wind from the E, and by the afternoon, it goes glassy. The swell is only 3ft to 3ft, but it’s a clean SSE swell with a period of 9 to 11 seconds. The energy is low (368 to 388), but for a reef break, that’s clean, fun-sized surf with no crowds to worry about.

Now, the big one. If you can wait, Saturday the 1st of August is the pick of the entire forecast. The swell jumps to 6ft from the SSW, with a period of 16 seconds. That’s a long-period groundswell, and on a reef, it’s going to be lined up and powerful. The wind is glassy in the morning, and the combined energy is a very strong 1621. This is excellent surf for experienced surfers. The crowd profile is “sometimes,” so you might have a few others, but the quality will be worth it. Sunday the 2nd holds similar, with a glassy 5ft SSW swell, energy still strong at 1102.

Further out, Tuesday the 4th of August looks huge for experts. The swell hits 8ft from the SSW, with a very long 18-second period and a strong energy of 4550. The wind is a clean offshore. This is serious, powerful groundswell. It’s for experts only, and the reef will handle it well, but it’s going to be a heavy session. Wednesday the 5th stays solid at 7ft with a 16-second period.

So, the best on offer is the glassy, mid-sized groundswell on Saturday the 1st and Sunday the 2nd of August. The one later in the week, Tuesday the 4th, is a monster for the experts. The first week is a write-off for quality, but the second week is where it’s at.

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.
