The Lowdown
Alright folks, Rusty here with a long look ahead to one of the most consistent reefs in the area. We've got plenty of action on the cards, so let's get into it.
The next two and a half weeks are looking good for Telescopes, a consistent advanced reef break that's exposed to the SW swell. We're gonna see a solid run of surf starting now, with a short lull right at the very end. The water's sitting pretty average for this time of year, no major surprises temperature-wise.
Right off the bat, this Saturday morning (12th September) we're looking at a beauty. A 5ft SW groundswell with a long 19-second period is pumping in, and the wave energy is very strong (2103). The easterly wind is offshore, keeping it glassy. It's a touch big for beginners, but for the experienced crew, this is about as good as it gets. The afternoon picks up to 6ft from the SW with the same long period and even stronger energy (3058), with a light cross-offshore breeze. This Saturday is a real standout.
Sunday morning (13th) holds some size at 7ft from the SW, but the wind picks up and goes cross-offshore. It's still clean and rideable, but the quality takes a step back compared to Saturday. The energy is still very strong (2370). This pattern of solid, clean surf continues through Monday and Tuesday, with the swell easing slightly to around 6ft to 5ft. Tuesday morning (15th) is a good call with 6ft SSW swell and improving conditions.
Mid-week, the swell settles into the 5ft to 5ft range, still with a long period and cross-offshore winds. The energy dips to moderate (997) on Wednesday morning (16th), but it's clean and consistent for the experienced surfer.
Pushing into the second week, the run of swell continues but loses a bit of its shine. We see a drop in size to the 4ft - 4ft range by Friday the 18th with moderate energy. A nice little pulse kicks back in on Saturday the 19th with a 5ft SW swell and a very long 18-second period, but the moderate onshore-cross wind keeps it from being top-tier. Sunday the 20th looks solid again – a 7ft SSW swell with strong energy (1970) and light, clean conditions. That afternoon is another highlight for the second week.
The week of the 21st has more of the same – consistent 4ft to 5ft SSW swells. The real special mention goes to Thursday morning the 24th. It's small at 3ft from the SSW, but the wind goes glassy. For a reef break that can handle a long period, this will be a dream for a longboard or a fish. The final weekend sees the swell dropping right off to under 3ft with fading energy. The run is basically done by Saturday the 26th, with only a few small, weak leftovers into Sunday.
So, there you have it. A long, consistent run of surf at Telescopes. The absolute standout is this Saturday. For the second week, keep an eye on Sunday the 20th and that glassy morning on Thursday the 24th.
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.
