The Lowdown
G'day, Rusty here. We’ve got a solid run of swell on the way for Telescopes, but the first few days are a bit of a mixed bag. The water’s sitting at 85°, which is about average for this time of year, so nothing weird going on there.
The pattern kicks off from Tuesday morning, August 4th, with a medium-period SSW groundswell at 4ft, but a 12 mph northerly breeze puts a cross-shore chop on it. The combined swell energy is moderate (1293), but the wind’s messing with the surface. Tuesday arvo gets worse – a cross-onshore blow and bigger numbers, but it’s a write-off. Wednesday morning, August 5th, is a bit better with a lighter northerly, but the swell is still only 5ft and the period’s dropped to 15 seconds. The energy’s moderate (1405), but the surf is still marginal. The whole of Thursday, August 6th, is a letdown with a bigger 6ft SSW swell but poor wind conditions making it choppy and messy. Friday, August 7th, is similar – the swell’s getting cleaner in the arvo though, with a 7ft SSW swell and a hint of cross-off wind, but the risk of thunderstorms is a worry.
Now, the real standout starts on Saturday, August 8th. The morning brings a 7ft SSW swell with a 16-second period, and a light 6 mph cross-off wind from the NE. The combined energy is strong (2108), and the surf is clean. By Saturday afternoon, it goes glassy – a 3 mph easterly breeze, zero chop, and the same 7ft swell. This is the best on offer early on. Sunday, August 9th, keeps the clean theme going with a 6ft SSW swell and cross-off winds, but the period drops to 15 seconds. The energy is still strong (1639), but it’s not quite the peak of Saturday.
Monday, August 10th, has a bit of a split. The morning’s a 5ft SSW swell, but the afternoon gets interesting – a 4ft S swell with a very long 21-second period. The energy spikes to 2346, and it’s clean. That long period means the waves will have plenty of push and shape, but at a reef break like Telescopes, it’s an expert’s zone. The rest of the week from Tuesday, August 11th, through to Friday, August 14th, is a mix of clean mornings and slightly choppy afternoons, with swell sizes ranging from 4ft to 6ft from the S and SSW. The energy is moderate to strong, but the consistency is there.
The second week is where it gets really exciting. Saturday, August 15th, starts with a 4ft S swell (19-second period) and glassy conditions, then the arvo bumps up to 6ft SSW. The energy is strong (2089). Sunday, August 16th, is clean and consistent, with a 6ft SSW swell. Monday, August 17th, has a small 3ft S swell in the morning, but the arvo brings a 5ft S swell with a 19-second period and glassy conditions – that’s a surprise packet. Tuesday, August 18th, is a massive highlight: a 7ft S swell in the morning, then a 7ft S swell in the arvo with dead calm, glassy conditions. The energy is very strong (2332). This is the best of the whole forecast period. Wednesday, August 19th, wraps it up with a 6ft SSW swell and offshore winds, then glassy conditions in the arvo.
For the beginners, the swell stays over 5ft for most of the good days, and over 8ft on the Tuesday arvo, so that’s expert territory. The long-period swells (over 15 seconds) are a caveat – they’ll be better for point breaks and reefs, but Telescopes is a reef, so it’ll handle it. Crowds are sometimes an issue here, so be ready for company on the standout days.
The biggest gap is right at the start – Tuesday and Wednesday arvo are poor, and Thursday is a write-off. But from Saturday morning, it’s a solid run for the rest of the 16 days.
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.
