The Lowdown

Hey folks, Rusty here. We’ve got a solid stretch of surf on the horizon, all pointing to one spot: Telescopes. This is a consistent, exposed reef break that handles a South West swell direction perfectly. The water’s sitting at about 85°, which is pretty normal for this time of year, so no surprises there.

The pattern sets up with a decent pulse of swell kicking off Tuesday the 11th of August. We’re looking at a 7ft south groundswell with a very long 17-second period – that’s proper energy moving through, with combined energy hitting 3531 (strong). The wind is cross-off from the SSE at 12 mph, keeping things clean. This is one of the standouts. The afternoon does drop off a bit with a touch more cloud and a score that’s a little lower, but the morning is where it’s at. This is advanced territory – that size and power is not for beginners.

Wednesday the 12th and Thursday the 13th settle down a touch, with swell dropping to around 6ft to 6ft, still from the south, periods around 14 to 16 seconds. Moderate energy in the 1700-2000 range. The wind stays favourable – cross-off or clean. Thursday afternoon is a real gem: 5ft with a 19-second period (2009 energy) and glassy conditions. That’s a sweet spot for experienced surfers. The swell is long period, so at a reef like this it’ll wrap in nicely, but beach breaks nearby might get a bit straight.

Friday the 14th morning is a beauty – glassy, offshore wind from the ESE at only 3 mph, 6ft south swell, clean as a whistle. That’s another standout. The afternoon goes a bit messy with a cross-shore NNW wind kicking up, so aim for the early session.

Saturday the 15th morning is glassy again, offshore, 5ft south swell – perfect conditions for the experienced crew. The crowd factor at Telescopes can be “sometimes” busy, so expect company on a morning like this.

Sunday the 16th is smaller, around 4ft, but glassy with super light winds. It’s a good option for a more relaxed paddle.

We then see a bit of a lull Monday the 17th with only 4ft, but the wind is offshore or glassy, so it’s still rideable for the die-hards.

Then we ramp up again Tuesday the 18th. The afternoon and Wednesday the 19th are the real highlights of the second week. Tuesday afternoon brings 6ft south-southwest swell, 16-second period, and combined energy of 3036 (strong). Wednesday morning pushes to 8ft with an 18-second period and 3170 energy – that’s powerful. Winds are cross-off and gentle. This is for advanced surfers only – 8ft and over is expert territory. There’s a solid run from the 20th through the 22nd of August with 7ft to 7ft south-southwest swells, clean cross-off winds, and excellent conditions for experienced surfers. The energy stays high in the 2000s.

Towards the end of the window, from the 23rd up to the 26th of August, we’ve got a mix of 5ft to 7ft swells, still clean or glassy in the mornings. The 25th and 26th mornings are particularly tidy.

Overall, Telescopes is the only break in the game, and it’s delivering a consistent run of quality, especially the first Friday and Saturday mornings, and that Tuesday/Wednesday spike in the second week. A long period south swell on an exposed reef with clean winds – you don’t get much better. Keep an eye on the wind shifts in the afternoons; early sessions are the go.

Stay stoked,
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.
