The Lowdown
Alright, listen up. Rusty here with the goods on our local lineup.
Water temps are sitting around 85°, which is normal for this time of year. Not a big deal.
The only real game in town for the next couple weeks is Telescopes. It's a proper reef that gobbles up this South and South-Southwest groundswell.
From Wednesday the 9th through Friday the 11th, it's a bit of a grind. We've got 4 to 6 feet of S/SSW swell with periods around 15-17 seconds. That's a nice long groundswell for the reef, but the wind is a steady 12 mph cross-off from the SSE. It'll be clean enough, but not perfect. The energy is strong, sitting in the 1200 to 1400 range. You'll have to deal with the chance of a thunderstorm rolling through.
Now, Saturday the 12th. That's the one you circle. We get a gorgeous 4 to 6 foot SW groundswell with an incredible 19-second period. The combined energy hits 2000 and then over 3000 – that's a big push. The wind goes dead calm. Zero mph. Totally glassy. The morning will be a bit smaller at 4 feet, ideal for a reef. The afternoon bumps to 6 feet, so that's expert territory, but it will be absolutely perfect. It's an advanced wave and it can get a crowd, but on a day like that, you just have to be in the water.
Sunday the 13th holds at 6 to 7 feet from the SW, but the wind picks back up to a cross-off. Still clean and solid, but the magic of a dead-calm ocean is gone. Monday the 14th drops to 6 feet, but we get a light offshore wind from the East in the morning. That'll be a nice, clean paddle.
From the 15th through the 18th, it settles down to 4 to 5 feet with shorter periods (13-15 seconds). The winds are moderate cross-off or cross. The energy drops from about 1200 to 950. It's surfable, but not the big show of the first weekend.
Second week, things get interesting again. From the 19th to the 24th, we see another clean pulse of SSW swell. Heights of 3 to 6 feet, but the winds look fantastic. We've got glassy conditions on the 19th, 20th, 21st, and 23rd afternoons with that dreamy 18-second period again. The energy is back up around 1200-1400. It's a long way off, but it has the potential to be just as good. Keep an eye on Saturday the 19th morning for a 4 foot glassy wave, and Sunday the 20th and Monday the 21st afternoons for 5 to 6 feet and glass.
So, to put it plainly: Saturday the 12th is the standout. Don't miss it. The weekend after that (the 20th) looks promising too. A solid, solid run for this reef.
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.
