The Lowdown

Alright, this is Rusty, and I’ve got the outlook for Telescopes dialed in. We’ve got a solid run of south swell energy coming our way, so let’s get into it.

Overall, we’re looking at a prolonged period of surf at Telescopes, with the first proper action kicking off on Thursday the 13th of August. The water here is sitting at a warm 85°F, which is about average for this time of year, so no surprises there. The swell direction is from the south, right in the sweet spot for this exposed reef break.

Thursday the 13th is a bit of a mixed bag. The morning offers up a 5ft south swell with a 14-second period, but it’s a bit of a wash with cross-off wind and the wave energy is very strong (1586). The afternoon drops to 5ft and gets a bit cross-choppy. This day is more of a warm-up.

Friday the 14th is where it starts to get interesting. Morning sees a clean 6ft south swell (16 sec period) with light cross-off breeze. The afternoon builds to a solid 7ft south swell (15 sec period), still clean and offering excellent conditions for experienced surfers. The wave energy is pumping into the very strong range (2202). This is a standout session for those who can handle it.

Saturday the 15th is a beauty. The morning is glassy – glassy! – with a 5ft south swell (14 sec period). The combined energy is still strong (1457), but that flat, windless surface will make it a dream for anyone on a longboard or a fish. The afternoon stays clean with a smaller 4ft.

Sunday the 16th sees the swell easing a bit, but the morning is still clean at 4ft from the south (15 sec period). The afternoon gets a bit messy with cross-shore wind. Then there’s a bit of a lull on Monday the 17th with smaller 4ft to 3ft south swell, but still clean. The real next standout window opens up on Tuesday the 18th.

Tuesday the 18th is a hidden gem. Morning brings a clean 5ft south-southwest swell (16 sec period) and the wave energy is already very strong at (1991). The afternoon jumps even higher to 6ft and the energy rockets up (2683). With light offshore winds, this is going to be excellent for experienced surfers.

Then we hit a serious pulse. Wednesday the 19th is for the brave. We’re looking at 8ft in the morning and then a solid 8ft in the afternoon from the south-southwest (18 sec period). This is very long-period groundswell, which will make Telescopes a proper freight train – experts only. The wave energy is massive (3544 and 3997). That’s a big, powerful ocean.

That energy holds through Thursday the 20th (8ft to 7ft) and into Friday the 21st, all staying clean with cross-off winds. Saturday the 22nd sees that southerly swell build back up to 8ft again with very strong energy (2553). It begins to taper off from Sunday the 23rd into Monday the 24th, with clean 5ft to 5ft swell.

After a drop to smaller 3ft surf on Tuesday the 25th, another swell fills in on Wednesday the 26th with a nice 6ft to 6ft south-southwest groundswell (16-17 sec period). The clean conditions hold, and this leads into another standout morning on Thursday the 27th with a clean 5ft south-southwest swell (15 sec period) and light winds. The energy is still strong (1198). It’s a great way to close out the run on Friday the 28th with clean but smaller 4ft waves.

If I had to pick the absolute best on offer, it’s the Friday 14th afternoon and Tuesday 18th for that big, clean, powerful swell with light winds. The Saturday 15th glassy morning is a must for anyone chasing perfection. The high-energy days around the 19th to 22nd are serious, powerful surf for the experienced crew.

Stay stoked, and keep an eye on the horizon.

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.
