The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of swell on the cards for Telescopes, a consistent advanced reef break that’s exposed to the SW. The water temp is sitting at 85°F, right around average for this time of year – no surprises there.
The action kicks off on Friday morning, July 31st. We’re looking at a clean 3ft SSW swell, with a super long 17-second period. The wind is a gentle cross-offshore breeze from the SE, keeping the waves tidy. The combined energy is moderate at 931. Afternoon sees the swell bump up to 4ft, but the tide might be a bit tricky.
Saturday, August 1st, stays in the same groove with a 5ft SSW swell in the morning, but the cross-shore wind in the afternoon will put a bit of a bump on the surface. Sunday morning, August 2nd, is where it starts to get tasty. Clean 5ft SSW swell with a 16-second period, light cross-offshore wind, and the energy is climbing to 1059. This is excellent for experienced surfers.
Monday, August 3rd, is a standout morning. We’ve got offshore wind from the ESE, 5ft SSW swell, and it’s glassy. The energy is moderate at 825. The wind swings to glassy calm in the afternoon. Then Tuesday, August 4th, sees the swell building to 5ft in the afternoon, but the wind goes cross-shore from the north, so it won’t be as clean. Wednesday the 5th and Thursday the 6th are a bit of a write-off for paddle surfing as the wind picks up strong from the north, creating a lumpy cross-chop. The swell is pushing 7ft, so it’s got grunt, but the surface is messy. That setup might be more interesting for the kite crew.
The real standout is the first week of August. Friday, August 7th, delivers a clean 7ft SSW swell with a 18-second period and a gentle cross-offshore breeze. The energy is strong at 2844. This is a big, powerful groundswell – perfect for a reef like Telescopes. Saturday, August 8th, has a great afternoon slot with a clean 7ft SSW swell and light offshore wind. Sunday, August 9th, is another cracker with offshore winds and clean 6ft to 7ft surf.
The absolute best of the whole run is Tuesday, August 11th. This is a serious session. We’re looking at a 8ft to 10ft S swell, with a 19-second period. The wind is glassy calm in the afternoon and light cross-offshore in the morning. The combined energy is massive at 5689 and 5214. This is exceptional, expert-level surf. The only caveat? That long period groundswell, over 15 seconds, can be a bit straight at some beach breaks, but for a reef like Telescopes, it’ll be a thing of beauty. It’s a long way out, so it’s a promising call, but it looks like one for the books.
The following week holds consistent swell, with the 13th and 14th of August offering clean, 6ft to 7ft surf with good energy. The 15th keeps the size up but the wind picks up a bit. Crowds are possible at Telescopes, but with that size, it’ll thin out the pack.
Stay safe, catch a few.
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.
