The Lowdown

Rusty here with the look ahead for Telescopes. This is all about one reef break that’s going to see a solid run of South and South-Southwest groundswells. The water temp is about average for this time of year.

The pattern kicks off Wednesday August 12th, and it’s already pumping. We’ve got a 7ft south swell rolling in with a very long 16-second period. The combined energy is moderate (1978), but the catch is a cross-off wind. It’s not unsurfable, but it’s not perfect. The morning is the cleaner call.

We spend the next couple of days with similar sizes, around 5ft to 6ft, and that long-period groundswell keeps the lines nice. There’s a touch of cross-chop in the afternoons, so mornings are the go. By Friday August 14th, things start to lock in. The morning is clean with a light cross-off, but the real standout is Friday afternoon. It’s glassy, dead calm, with a 7ft south swell at 15 seconds. That is a proper session waiting. The energy jumps to a very strong 2005 and conditions are described as excellent for experienced surfers.

Saturday the 15th and Sunday the 16th drop off a bit in size and energy, but it remains clean in the mornings. The swell direction goes a little SSW, which is right in the wheelhouse for Telescopes. Then the real meat arrives.

Tuesday August 18th morning brings back a nice 7ft SSW groundswell with a 17-second period. The combined energy is a robust 2179, it’s clean with gentle cross-off winds, and it’s right in the sweet spot. Wednesday August 19th is the absolute peak. Both the morning and afternoon deliver 8ft to 8ft SSW swell, periods of 17 to 18 seconds, and combined energy readings of 3491 and 3867. That’s strong-to-very-strong wave energy. It’s clean, cross-off, and described as excellent for experienced surfers. This is the best the window has to offer. This size is for the experienced crew.

From Thursday the 20th through Sunday the 23rd, the swell holds solid – consistently over 7ft to 8ft – but the wind picks up to a moderate breeze. It stays cross-off and clean, so it’s still very surfable, just not as glassy as the peak. By Monday the 24th and Tuesday the 25th, the size drops a little to the 5ft to 6ft range, but the wind backs off to a light breeze, and the conditions are excellent. It stays like that into the end of the month, with clean mornings and a slow fade in energy.

For the second week, the standout is still August 19th, but the mornings of the 24th and 25th are also clean with light winds and solid SSW swell. It won’t be as big, but it will be fun and clean.

Overall, there are no real gaps in surf – this break is consistent and exposed, and it’s on from start to finish. The absolute peak is the 19th, but the whole run from the 14th onward delivers.

Rusty, signing off.

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.
