The Lowdown
Alright, this is Rusty. Let’s get into it.
We’ve got a solid run of surf coming up at Telescopes. This is a reef break, taking SW swell, and it’s a consistent one for the advanced crowd. The water temp is about 85°, which is pretty average for this time of year – nothing wild.
It starts off Thursday the 30th of July. Not the headline act – a 3ft SSW swell with a moderate cross-off breeze. The energy is moderate (966). Friday the 31st looks better in the morning with a light breeze and a clean 3ft swell, but still moderate energy (931). The afternoon gets to 5ft with stronger energy (1338), but the wind stays cross-off.
Now, the good stuff. Saturday the 1st of August morning – this is one of the best windows early on. You’ve got a 5ft SSW swell, light cross-off wind, clean conditions, and moderate energy (1217). The period is a long 17 seconds, so real groundswell power with long lulls. Excellent for experienced surfers. Sunday the 2nd keeps the quality: 4ft down to 3ft, light winds, and clean. Very surfable.
Monday the 3rd is mixed. The morning has a 5ft swell and gentle cross-off, but the afternoon turns onshore with a WSW wind – that’s your cue to paddle in. Tuesday the 4th of August morning is a true standout. You get a 5ft, 16 second SSW swell, completely glassy, with barely a breath of wind. The energy is strong (1089) and it’ll be clean, but expect crowds sometimes.
Wednesday the 5th is a washout – strong cross-onshore wind, choppy, and poor. Thursday the 6th stays rough with moderate cross-shore wind and lumpy surf, even with the swell at 6ft.
But then, Friday the 7th of August morning delivers. A 6ft SSW swell, light cross-off breeze, and very strong energy (1905). This is expert territory, but could be the best paddle session of the week if you’re game. The afternoon hits 7ft with almost no wind. Clean, powerful, and long period.
The weekend of the 8th and 9th keeps it going: Saturday morning has a 7ft S swell with a moderate cross-off, but it’s clean. Sunday the 9th afternoon is a gem – 3ft but from the S with a 19 second period and offshore wind, energy is very strong (1808). Glassy perfection on the reef.
Monday the 10th of August is another highlight: clean, 5ft to 5ft S swell, gentle breeze, excellent conditions. Energy stays high. Tuesday and Wednesday the 11th and 12th drop off a bit with moderate winds and less ideal tide comments, but still surfable.
Looking further out to Thursday the 13th of August morning – this is a big one. A 7ft SSW swell with a staggering 22 second period and energy through the roof (4626). The wind is light cross-onshore, so it’s not perfect, but the raw power is enormous. The afternoon reaches 8ft with a 20 second period. Only for experts – very big, very long period groundswell. Friday the 14th stays big, 10ft in the morning with 17 second period and cross-shore wind. These later days are promising but less certain this far out.
The standouts are Saturday the 1st of August morning and Tuesday the 4th of August morning for clean, powerful waves. The big swells on the 13th and 14th are for the legends only – bring your big wave board.
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.
