The Lowdown
Alright, let’s talk about Telescopes. Only spot in the region worth looking at for the next couple weeks. It’s an advanced reef break, consistent, and the water temp is about normal for this time of year – no weird anomalies.
Starting Monday the 10th, we’ve got a 5ft S swell, period 14 seconds, with cross-off wind from the SSE. Wave energy is strong (2174), but the tide makes it a bit marginal. Not the day to go nuts.
Tuesday the 11th, morning is the call – 7ft S swell, period 17 seconds, cross-off from the SE. That’s a groundswell with serious grunt (3287). Clean, powerful, for experts only. The afternoon gets a little bumpy.
Wednesday the 12th holds at 6ft, still cross-off, but the afternoon gets cross-chop. Morning is clean.
Thursday the 13th drops to 5ft, period 12 seconds, light cross-off. Clean, but not huge. Energy moderate (1487).
Friday the 14th is the standout. Morning has 7ft S swell, period 16 seconds, light cross-off. Then Friday afternoon turns glassy – no wind, 7ft swell, period 15 seconds. That’s the one. Clean, powerful (2146), experts only.
Saturday the 15th drops to 5ft, still clean cross-off. Sunday the 16th is smaller at 4ft but glassy in the morning – nice and clean. Energy moderate (948).
Monday the 17th goes small – 4ft SSW, period 14 seconds. Clean cross-off, but energy is lower (678).
Tuesday the 18th brings a new pulse – 6ft SSW, period 19 seconds, very long period. That’s powerful and well-shaped, but at a reef it’ll run a bit straight. Still, clean cross-off and strong energy (2596) make the afternoon excellent.
Second week: Wednesday the 19th jumps to 8ft SSW, period 18 seconds. Morning clean, energy very strong (3973). Experts only. Thursday the 20th holds at 8ft, clean morning. Friday the 21st is 7ft, clean all day. Saturday the 22nd drops to 6ft, still clean but wind picks up. Sunday the 23rd holds around 5ft, clean. Monday the 24th dips to 4ft, then Tuesday the 25th bounces to 5ft SSW, period 16 seconds, light cross-off, clean – a solid finish.
The true standout is Friday the 14th afternoon with glassy 7ft S groundswell. Second best is Tuesday the 11th morning with 7ft clean and long period. Crowds at Telescopes can show up sometimes, so on the good days you might see a few other heads.

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.
