The Lowdown
Alright, this is Rusty, and I’ve been staring at the charts for our little slice of coastline. There’s only one break that’s showing any real promise in this whole 16-day window, and that’s Telescopes. It’s an advanced-level reef break, so this isn’t one for the grommets or the Sunday foam-stompers. The ocean has been throwing a lot of energy our way, but conditions have been a bit messy for a while. There’s a bit of a wait before things really clean up, but when they do, there are some absolute gems on the horizon.
Right now, and for the next few days, the surf is pretty average. The swell is coming in from the SSW with chest to head-high sets (around 4ft), but the wind is mostly a moderate cross-offshore breeze, and that’s keeping the surface from being perfect. The water temperature is sitting at 86°, which is about 2° above the long-term average, so it’s feeling slightly warmer than usual for this time of year—nothing too crazy, but you’ll notice it. The wave energy has been in the moderate to strong range, but the quality hasn’t matched the power.
The first real standout window opens up on Saturday the 12th of September. That morning, we’re looking at a 4ft swell from the SW with a long 19-second period, and the wind is going offshore from the ESE. That is a recipe for some clean, lined-up reef waves. The combined energy is solid, and the conditions are described as excellent for experienced surfers. This is your best early call.
Then, on Saturday the 19th of September, things get even better. We’ve got a 8ft SSW groundswell hitting in the morning with a 17-second period, and the wind is light offshore from the ESE. The wave energy is massive. That is a serious swell, and on a reef, it’s going to produce some heavy, powerful waves. This is strictly for the experienced crew. It’s over 8ft, so it’s not for beginners at all. The afternoon holds at 7ft with light winds, so there’s a full day of quality on offer. Crowds are possible here at Telescopes, and with waves this good, you can bet it’ll be busy.
There’s a solid run of good surf from the 16th to the 21st, with plenty of days showing excellent conditions. The periods are consistently long, between 14 and 19 seconds, which is groundswell territory. That means the waves will have plenty of push and shape, perfect for a reef like Telescopes. The winds are mostly light and cross-offshore or offshore, so the surface should be clean for most of that week.
So, to sum it up: don’t get too excited about the next few days. Wait for the 12th of September for a clean, solid session, and then mark your calendar for the 19th of September for the biggest and best swell of the outlook. That’s the one to aim for.
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.
