The Lowdown
Alright, Rusty here, and I've got the outlook for the only show in town: Telescopes.
We're looking at a solid 16-day window with a consistent, long-period SSW groundswell that's got a lot of energy behind it. The water's sitting at 85°F, which is pretty much spot on for this time of year, so no wetsuit worries, just boardshorts. The forecast is almost entirely dominated by a strong, deep ocean pulse, and for the first few days, the conditions are going to be very, very clean.
The best bet is to get on it early. Sunday, the 2nd of August, is a standout. The morning sees a 5ft SSW swell wrapping in with a 16-second period – that's proper groundswell and a lot of energy. The wind is a light cross-offshore from the SE, and the afternoon goes glassy with a WSW breeze. That's a magic window right there. Monday the 3rd is also a ripper, glassy all day with a 5ft, 15-second swell. The swell energy is a bit lower, but the quality of the wave will be perfect.
Things get a bit more critical later in the week. Wednesday the 5th has a solid 5ft swell and a clean offshore wind from the ENE, which is a major positive. But by Thursday the 6th, a strong NNW wind kicks in, blowing like crazy at 25 mph, churning up the 6ft swell. That's a write-off, with strong cross-shore conditions making it messy. That runs into Friday and Saturday, where the swell gets bigger (8ft on Friday afternoon) but the wind stays strong, making it look more like a kite-surfing setup than a paddle session.
We hit a bit of a lull, but it's not dead. The swell pulses again on the 9th of August, with a 6ft, 15-second swell and a clean cross-offshore breeze. The standout in the second week is definitely Saturday the 15th of August. The morning sees a 7ft, 18-second S swell with a massive energy reading. The wind is a clean cross-offshore. That's a big, powerful, long-period groundswell – it's going to be heavy and only for the experienced, but it's the best of the second week, no question.
This break is a reef, so it handles the long-period stuff well. The crowds are listed as "sometimes", so with this quality of swell, expect company. It's a consistent spot, so the waiting isn't too bad, but the 16th brings more clean, solid surf to wrap it all up.
Rusty out.

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.
