Alright, now let’s talk about it in feet and Fahrenheit for the crew.
We’ve got a solid run of surf on the cards, but it’s not all gonna be perfect. The biggest story is a long, consistent stretch of groundswell filling in from the south, starting this Saturday afternoon and just keepin’ on rollin’. The water’s sitting at a warm 86°F, which is a touch above the long-term average for this time of year – feels about normal, maybe a little on the toasty side.
Let’s start with the pick of the bunch. Telescopes is the only break in the game here, and it’s a consistent, exposed reef. Saturday afternoon kicks things off with a sneaky little 2ft swell from the south, but with a 18-second period – that’s proper long-period groundswell. The wind is glassy from the northeast at just 3 mph. Insanely clean conditions. The combined energy is moderate at 790. For a reef break like this, that long period is gonna wrap in and give you some nice, lined-up walls. A bit small, but it’s a promising start.
Now, Sunday morning (July 5th) is where it starts to get exciting. Clear sky, dead calm wind – glassy. Swell bumps up to 4ft from the south, still a very long 15-second period, and the energy is moderate at 813. This is a proper morning session. Sunday afternoon gets a bit messy with a cross-onshore breeze, and the swell hits 5ft – still cleanable but not the highlight.
Monday (July 6th) is a bit of a write-off with onshore wind and a risk of thunderstorms. We skip that.
Tuesday (July 7th) is a redemption day. Morning has a cross-offshore breeze from the southeast and clean 4ft swell. Then Tuesday afternoon? Glassy again, with zero wind and a 4ft south-southwest swell at 15 seconds. Energy is up at 831. That's a beauty window.
Wednesday (July 8th) blows onshore again, so we ride through it.
Then we hit the real standout. Thursday morning, July 9th – this is the best on offer by a long shot. Clear sky, glassy northeast wind at just 3 mph. Swell is a solid 5ft from the south-southwest at 14 seconds. That’s expert-level conditions for the experienced crew. The combined energy is strong at 1083, and the wave comment calls it excellent for experienced surfers. This is the one to circle on the calendar.
The rest of that Thursday and Friday (July 10th) hold clean conditions with cross-offshore winds and solid 5ft to 5ft swell. Nothing wrong with that, but the Thursday morning glass is the highlight.
The second week rolls on with consistent clean surf, mostly in the 3ft to 4ft range with lighter winds. Tuesday morning, July 14th, stands out with a 3ft swell but a 17-second period – very long period groundswell – and offshore to glassy winds. The reef setup at Telescopes is perfect for that kind of energy. The combined energy is moderate to strong at 993. Wednesday and Thursday look clean too, with glassy afternoons.
Even right through to Sunday, July 19th, we’ve got a late pulse showing up – a 2ft swell from the south at a massive 20-second period, then later that afternoon it’s glassy with a 3ft south-southwest swell at 19 seconds and energy at 980. That’s a long-range promise, but worth keeping an eye on.
Crowds can be an issue here at Telescopes – it says “sometimes” – so for that Thursday morning glass session, you might wanna paddle out early.
Overall, this is a really solid run. No gaps. Just a few days where the wind messes it up, but plenty of clean windows. Tide conditions are not given, so check your local charts.

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.
