The Lowdown
Alright, Rusty here, checkin’ out what’s cookin’ at Telescopes. This is a reef break that loves a solid SW groundswell, and that’s pretty much the whole menu for the next sixteen days.
First up: the water’s sittin’ at about 85°, which is nearly a degree warmer than normal for this time of year. Feels like a bathtub, in a good way.
The first few days are a warm-up. Thursday the 3rd has 5ft of SW swell with a 14-second period, but the wind is crossin’ it up from the SE. The combined energy (789) shows there’s some push, but the conditions are just okay. Through Friday the 4th and the weekend, the swell drops a little and energy slips into the 500s. The wind stays cross-off, so the surface will be tidy, but it’s not gonna light up.
The real deal starts on Tuesday the 8th. Tuesday afternoon goes glassy – dead calm – with 4ft of SSW swell at 17 seconds. That energy jumps to 1395. That’s moderate-to-strong, and with zero wind on the face, the reef will be servin’ up clean, lined-up waves. This is the top session early on.
Wednesday the 9th and Thursday the 10th keep the quality high. Wednesday morning brings 5ft of swell at 15 seconds with a light offshore ESE breeze. Clean. Energy stays over 1200. You’ll want to be out there early. Thursday morning is also a gem: 4ft, 16 seconds, barely a puff of wind from the SE. The consistency here is solid, so the sets keep comin’.
Friday the 11th morning is another highlight. 5ft of SSW swell at 16 seconds with a pure offshore ESE wind. That’s perfect for a reef. Energy at 1337 – punchy and powerful.
The second week keeps the swell size up, but the wind gets a little more playful. Sunday the 13th afternoon shows 6ft of SW swell at 17 seconds – that’s gettin’ chunky, combined energy 1823 – but it’s cross-off from the SSE. Still got power. Tuesday the 15th has 6ft again, and the afternoon goes glassy. That’s a serious session right there.
By Wednesday the 16th the wind turns onshore and the quality fades. A short blank spell follows, but Thursday the 17th shows promise with light winds and glassy afternoon conditions, though the swell is smaller at 4ft and energy drops to 521. Fun, but not a standout.
Best bet: get in the water Tuesday afternoon the 8th, all day Wednesday the 9th, and Thursday morning the 10th. That’s where the clean conditions, long period groundswell, and consistent waves all line up. The long period (15-17 seconds) gives the waves shape and power, and on a reef like Telescopes, the lines will wall up real nice. The gap after the 17th is just a few days of weaker energy, but things can change.
Lock in that mid-month window. 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.
