The Lowdown
Alright, Rusty here. Let's break down the next sixteen days of surf for this one spot.
We've got one break in the mix, and it's going to be a bit of a rollercoaster. The window opens on Wednesday, July 29th, with some clean, fun waves. The water temp is about 83°F, which is pretty average for this time of year, so no drama there.
Telescopes is the only show in town. It's an advanced-level reef break that fires consistently and takes a direct hit from SW swells – and that's exactly what's coming. The direction is dead on.
Wednesday the 29th starts small and clean. Morning brings a 3ft SSW swell with a 14-second period – that's a long-period groundswell, so you're looking at proper, lined-up waves with good gaps between sets. The wind is a light cross-offshore, so the faces will be clean. The energy reading is 404, moderate, but it's just waking up. The afternoon builds a touch to about 3ft and the energy jumps to 595. Solid, clean surf for the experienced crowd.
Thursday the 30th looks even better. Morning kicks off with a 3ft SSW swell, but the period stretches out to 19 seconds – that's a very long period groundswell, full of grunt and shape. The energy is up to 924. Winds are light cross-off. This is the cream of the first few days. The afternoon picks up to 4ft, but the wind turns a little cross-shore, so expect a bit of texture.
Friday the 31st holds clean conditions in the morning, with a 3ft SSW swell at 17 seconds. Energy is 974. Afternoon has a risk of thunderstorms and the swell nudges up to 4ft, but the wind shifts a bit, taking the polish off.
Now, Saturday the 1st of August is a real standout. Morning delivers a 5ft SSW swell, 17-second period, and the combined energy is 1204 – strong. Winds are light cross-off, the conditions are described as excellent for experienced surfers. This is the highlight of the first week. Afternoon holds similar energy with clean conditions.
Sunday the 2nd of August is worth a special mention. The morning has a 5ft swell but a moderate breeze (12 mph) will put some bumps on it. The afternoon, though, is magic. The wind drops to a light air, it’s glassy, and the swell settles back to 3ft but with an 18-second period from the S. A clean, long-period set.
Monday the 3rd through Tuesday the 4th sees a dip. Swell size hangs around 5ft to 5ft, but winds go light cross-shore and the conditions turn marginal with questionable tides. The energy stays strong (over 1000), but the wind isn't playing ball.
From Wednesday the 5th of August, things get a bit messy. The swell starts pushing past 4ft, but the winds turn cross-shore and then cross-onshore. The energy readings are massive (1425 to 1637), but the quality is poor for a paddle. This is more of a kite session, to be honest.
Thursday the 6th of August sees the swell jump to 6ft with a 16-second period. Energy hits 2007. But the wind is a moderate cross-shore, creating chop. Not great.
Now, Friday the 7th of August is another standout. The swell is 6ft from the SSW, period 16 seconds, and the wind finally turns light cross-offshore again. Conditions are excellent for experienced surfers. Energy is high at 1601. This is a solid, powerful day.
Saturday the 8th of August looks promising again. Morning shows a 7ft S swell, 15-second period, with offshore winds. That’s clean, big, and hollow. This is experts only. The energy is huge at 1905. Afternoon drops back to 5ft with cleaner conditions.
From Sunday the 9th of August through to the 13th, the pattern holds: moderate to strong SW to S swells, mostly between 4ft and 7ft, with consistent cross-offshore winds. The energy readings stay high, often over 1000 and peaking at over 10,000 on Wednesday the 12th afternoon. The challenge is the quality flags are often "marginal" due to tide or wind, but there are pockets of excellent conditions, especially on the mornings of the 9th, 11th, and 13th.
The pick of the bunch: Saturday the 1st of August morning (5ft, clean, strong energy) and Friday the 7th of August morning (6ft, clean, excellent conditions) are your best calls. The afternoon of Sunday the 2nd of August is also a special, glassy moment. The rest is there for the taking, but you'll need to be sharp with the tide and wind.
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.
