The Lowdown
Alright folks, Rusty here, with a look at what’s shaping up over the next couple of weeks. We’re focusing on just one spot, really, and it’s a bit of a mixed bag. The water temp is sitting around 85°, which is about average for this time of year, so nothing too wild there.
We’ve got a solid run of groundswell coming through, but the wind is the main story. For the first week, from Tuesday the 8th through to the end of the weekend, it’s a persistent cross-offshore breeze out of the SSE and SE. It’s not perfect, but it’s workable. The swell is mostly in the 4ft to 7ft range, with a long period of 15 to 19 seconds. That kind of long-period energy really loves a reef setup like this. The combined wave energy is strong, so there’s plenty of power in the water.
The real standout here is Saturday the 12th. The morning session is looking tasty with a 5ft SW swell, a period of 19 seconds, and a clean cross-off breeze. That’s a recipe for some proper, well-shaped lines. The afternoon gets a bit bigger, 6ft, but the wind swings onshore, putting a little chop on it. For the experienced surfer, the morning is the clear winner.
The start of the second week, Monday the 14th, is another good call. Clean cross-off winds again, with a solid 6ft SW swell and 16-second period. Don’t sleep on it.
Things get a bit more interesting towards the end of the run. Friday morning the 18th, we get a rare moment of glassy conditions, no wind at all, with a 5ft SSW swell. That’s a window of pure, clean perfection for a reef break like this. And then Tuesday the 22nd morning, we see a 4ft S swell with a very long 18-second period and a light cross-off breeze. Just keep in mind, that is a long way out, so treat it as a promising possibility rather than a guarantee.
Because this is a consistent, advanced reef break, the crowds are sometimes a factor. The conditions will be best for experienced surfers, especially when the swell pushes over 5ft, and when it hits 7ft on Sunday the 13th, it’s expert territory only.
Keep your eyes on Saturday the 12th morning and Monday the 14th – those are the sessions I’d be circling on the calendar.
Rusty, signing off.

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.
