The Lowdown

Alright folks, Rusty here with a look at the window ahead for Telescopes. It’s a reef set-up that’s exposed to the swell and it’s been pretty consistent, so we’ve got action coming in waves, but we’ve got to wade through a bit of mediocrity first.

The water temp here is sitting at a balmy 84°F which is about normal for this time of year, so the trunks are all you’ll need.

We kick off on Tuesday the 15th, but honestly, it’s a slow start. The first several days are a bit of a letdown. Tuesday morning has some 6ft SSW groundswell mixing with a cross-off wind, but the combined energy is already pumping at 1273 (moderate wave energy), which is decent. But the afternoon goes cross, and the forecast calls it marginal. Wednesday and Thursday are holding steady with chest-high 5ft to 5ft swell, but the conditions are just okay – clean mornings but nothing to write home about. There’s a real flat spot in quality until the weekend.

The first real standout looks like Sunday the 20th. We’ve got a solid 6ft SSW swell rolling in early, with the combined energy hitting 1727 (still moderate, but pushing hard). But the real magic is Sunday afternoon: the swell settles slightly to 6ft from the SSW, a 16-second period, and the wind drops to almost nothing at 3 mph from the SSE. That is glassy, cross-off, and clean. It’s the first “excellent” call in the run, and it’s there for the experienced crew. That is your first window of pure, lined-up reef waves.

We cruise through Monday the 21st with more clean, 6ft SSW swell in the morning – another solid session. Then we get a bit of stormy weather mid-week, but the conditions hang in there. Tuesday the 22nd morning has a risk of thunderstorms but still 5ft of clean, cross-off S swell. It’s a little smaller but still “excellent” for the skill level.

Now, the real beast is lurking on the horizon. Saturday the 26th of September. That’s over a week away, so keep it on the radar but don’t book the week off yet. The morning sees 6ft SSW swell, but the period jumps to a massive 22 seconds, and the combined energy skyrockets to 4053 (strong wave energy). That is long-period groundswell pumping in. Saturday afternoon gets even heftier – 8ft SSW at a 20-second period, energy reading 4244 (strong). That’s going to be a proper dose of power. The catch? The wind on Saturday afternoon is cross, not offshore, so it’ll have a bit of texture. But the stand-out peak of the whole run is Sunday the 27th morning. We’ve got 8ft SSW swell, an 18-second period, and the wind is true offshore from the ENE at 12 mph, with combined energy at 3179 (strong). The forecast calls it “excellent” for experienced surfers. At this size, 8ft, it’s expert territory only. That’s the day to circle on the calendar – big, clean, powerful reef waves. The following Monday and Tuesday stay clean but drop back to a more manageable 5ft to 5ft range, which is still fun but nothing compared to that weekend power.

Overall, the first week is a patient game. The standouts are Sunday the 20th afternoon and then, if it holds, the weekend of the 26th-27th is the real deal. Get ready.

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.
