The Lowdown
Alright, Rusty here, let's talk about what's coming up.
Alright, so for the next couple of weeks, the surf scene is focused on Telescopes. Don't go expecting any secret slabs to light up; this is where the action is. The water temp is sitting at 85°, which is pretty much bang on average for this time of year, so nothing weird going on there.
Right now, we've got some decent groundswell pushing in, but it's a bit of a mixed bag. We're looking at a solid 4ft to 5ft of SSW swell, with a long period of 16 to 17 seconds. That kind of long-period groundswell, particularly from the SSW, is really going to groove along Telescopes. The problem for Thursday and Friday is that cross-off wind is blowing at 15 to 16 mph. It's not onshore, so it's manageable, but it will keep the surface a little bit textured. The combined swell energy is sitting between 1254 and 1625, which is strong, but the conditions just aren't dialled in yet.
Now, keep your eyes on Saturday the 12th. That's where it gets good. Saturday morning we see the swell bump up a touch to 5ft from the SW, with a very long period of 19 seconds and strong energy of 2102. The wind is still cross-off, but it's only 9 mph. But Saturday afternoon? That's the standout. The wind drops to a complete glass-off at 3 mph from the south, the swell builds to 6ft from the SW with a 19-second period, and the energy rockets to 3048. It's going to be clean, powerful, and really good. This is the one you plan around for experienced surfers that can handle that size.
The good news is this pattern holds for a while. Sunday the 13th holds excellent conditions with similar energy and a clean morning, and the glassy conditions keep popping up. Monday the 14th and Tuesday the 15th see the swell drop a little to 6ft, but it's still consistent and clean, even if the wind is a little more variable.
Looking further out, the second week has some great potential, but it's a little less of a sure thing. The 18th and 19th of September are showing some really promising windows. On Friday the 18th afternoon, we get the first hint with a 4ft SSW swell and glassy conditions. Then Saturday the 19th is a real cracker: 4ft of SW swell in the morning with a strong 18-second period, building to 6ft in the afternoon, all under glassy conditions. The energy is strong, and the wind is perfect. It could be the second real highlight of the window. The 20th and 21st keep the clean conditions and good size, with the swell slowly easing. By the 22nd we're dropping to smaller 3ft swell, but it's still a long-period groundswell with glassy conditions, so it's worth a paddle.
Just a heads up, by Wednesday the 23rd, the wind turns onshore and the quality drops right off, so the window really wraps up cleanly around the 21st and 22nd. This swell is very good for a reef like Telescopes, and the crowd can be an issue there as it can get "sometimes" busy, but with this much quality on offer, it's going to be worth sharing a few waves. The standout is easily Saturday the 12th afternoon, with that glassy 6ft SW groundswell. For the second week, keep Saturday the 19th burned into your calendar.

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.
