The Lowdown
G’day, Rusty here. Let’s talk about what’s happening at Telescopes over the next couple of weeks.
Right from the start, Monday the 7th and Tuesday the 8th are pretty dead. Small waves, messy wind, nothing to get you out of bed. Give it a miss for a few days.
Things wake up on Wednesday the 9th. A solid SW groundswell starts moving in, with a nice long period of 15 seconds. The combined swell energy is in the moderate range (1189), so there’s some life. Waves around 5ft to 6ft, but it’s a bit rough with those afternoon breezes and storm clouds around. Not perfect, but there’s a pulse.
Now, the good stuff. Saturday the 12th and Sunday the 13th bring a very long-period SW groundswell—19 seconds on Saturday! That’s proper power, with energy hitting 2780. Wave heights are between 6ft and 7ft, so this is for experienced surfers only. The wind’s cross-off, keeping the faces clean. This is the first real standout. Crowds can be expected, so get there early. That super-long period means the sets will be a bit more spaced out, but the waves will be well-shaped and punchy.
Monday the 14th is the pick of the first week. Light offshore wind in the morning, 6ft of clean, long-period SW swell (1614). Conditions are set to be glassy, and it’s rated as excellent for experienced surfers. That’s your day.
Things get a bit average mid-week around the 15th and 16th, with energy dropping off. Not much to write home about.
But the second week has another cracker. Thursday the 17th and Friday the 18th look clean again, with light winds and solid 6ft swell. Saturday the 19th is a monster: 7ft of SSW groundswell with zero wind and glassy conditions. That’s a 2909 energy reading—proper strong. This one’s for the experts only. Sunday the 20th keeps the trend going with a 8ft pulse, still clean in the morning. This second week is promising, but we’re far enough out to keep it in the hopeful category.
Water temp is sitting at 85°, which is about average for this time of year, so nothing unusual there.
Best bet: the stretch from Saturday the 12th through Monday the 14th, and then again the weekend of the 19th and 20th. If you’re chasing clean, powerful, long-period SW groundswell, Telescopes is your spot. Just remember, when it’s over 7ft, leave the foamies at home.
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.
