The Lowdown
Alright surfers, Rusty here. We’ve got one main event on the table for the next couple of weeks—Telescopes—and it looks set to deliver some serious sessions for the experienced crew.
The water temp is sitting at a balmy 84°, which is spot on for this time of year. We’ve got a real run of groundswell in the forecast, with periods often hanging around the 14 to 18-second mark. That long-period energy means the waves will have plenty of punch and shape, but at a spot like this, the sets will be a bit more spread out, making it easier to get into position.
This week kicks off with some solid action. On Monday the 14th, the morning session looks excellent for experienced surfers. We’re talking a clean 6ft swell from the SW with a very long 16-second period, pushed by a light cross-offshore SSE breeze. The combined energy is chunky at 1723 (moderate wave energy). The wind holds through Tuesday morning too, with a clean 6ft SSW swell, period at 15 seconds, and again cross-off airflow—strong wave energy at 1271. Definitely the standout sessions this week.
The afternoons through the middle of the week are more marginal, getting chopped up by a cross-shore wind. Wednesday the 16th brings a risk of thunderstorms and a stiffer 25 km/h cross-off wind, but the wave height drops to a still-fun 5ft, though the energy dips below 1000. The surf tails off a bit into the end of the week, with Friday looking pretty poor, especially in the afternoon.
We hit a reset on the weekend. Saturday the 19th sees a wildcard—a morning of heavy rain with an onshore W wind—but it picks back up Sunday the 20th. That Sunday afternoon brings a juicy 7ft SSW swell, 16 seconds, clean cross-off winds, and strong energy at 1976. That’s a genuine highlight. Monday the 21st keeps the love going with a clean 5ft swell and light winds.
Then, Rusty, we’ve got a potential banger on the horizon. For the second week, on Saturday the 27th, the models are lighting up. Sunday the 27th is the real standout of the entire forecast. The morning delivers a clean 6ft S swell with a *huge* 20-second period and very strong wave energy at 3778, coupled with a cross-off NE breeze. But the afternoon? Glassy. A 7ft SSW groundswell at 19 seconds, with the wind going glassy from the NNW, and energy peaking at 3779—that’s very strong wave energy. That’s the session you’d be dreaming about. It’s a ways out, so lock that date in, but keep your expectations high. That swell direction (SW/SSW) is bang on the mark for Telescopes, as it’s exposed to that.
Being a reef break that’s consistent and exposed, it won’t take much to fire, but with a couple of those late-period days getting over 5ft and pushing 7ft, this is strictly for the advanced crew. For the second week, that Sunday the 27th is the one to chase. From there, the energy settles back down to moderate levels in the 900s by Tuesday the 29th, but still offering clean morning waves.
So, don’t worry about the flat spells—there aren't any. The run looks long and promising. The best bets are this Monday and Tuesday mornings, and that potential all-timer on Sunday the 27th.
Stay salty.

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.
