The Lowdown
Alright folks, Rusty here. We’ve got a solid run of surf on the way at Telescopes, a reef break that’s exposed to the swell. The water is sitting at 85°F, which is about normal for this time of year, so no need to dig out the wetsuit.
We kick things off on Monday, July 27th. The morning is looking clean with a 3ft SSE swell pushing in at 10 seconds. The combined energy is moderate (382), and with a light cross-offshore breeze from the SSE, it’ll be tidy. The afternoon gets a bit more marginal, though, as the wind shifts onshore a touch.
Tuesday, July 28th, starts clean again with a 2.3ft SSW swell, but check out the period – 16 seconds. That’s a proper groundswell, with good energy (477). The light SE cross-offshore wind will keep it glassy. The afternoon sees a slight cross-shore chop creep in.
Wednesday, July 29th, is a beauty. Clean conditions all day with a 2.6ft to 3ft SSW swell, periods around 14 seconds, and a light cross-offshore breeze. Wave energy is moderate (402-403). This is a proper long, fun session.
Now, Thursday, July 30th, is a standout. The morning brings a 3ft SSW swell with a 19-second period – that’s very long-period groundswell, and the energy jumps to 924. The wind is light and cross-offshore from the SE, so it’ll be clean. This reef is going to handle that long period beautifully, offering up some proper lined-up walls. The afternoon gets a bit trickier with a cross-shore wind.
Friday, July 31st, keeps the quality high in the morning. Another 3.3ft SSW swell, 17-second period, light cross-offshore. Energy is strong (812). The afternoon has a risk of thunderstorms and a cross-shore wind, so morning is the call.
Saturday, August 1st, is the absolute peak of the first week. The morning is glassy – dead calm – with a 4.6ft SSW swell at 17 seconds. The energy is strong (1201). This is excellent for experienced surfers; the waves will have real power and the reef will line them up perfectly. The afternoon stays glassy, but the swell drops a touch.
Sunday, August 2nd, is another glassy morning. A 3.9ft SSW swell, 16 seconds, and energy is pumping (1269). The afternoon sees the wind pick up to a cross-shore breeze, so the morning is your window.
Monday, August 3rd, cleans up again. The wind is light and cross-offshore from the NE in the morning, with a 4.6ft SSW swell at 15 seconds. The afternoon turns glassy, but the swell is a touch smaller.
Tuesday, August 4th, the swell builds to 5.2ft, but the wind turns cross-onshore, so the quality drops. It’s a bit of a messy one.
Wednesday, August 5th, the swell holds at 4.3ft, but the period is a massive 20 seconds. The energy is very strong (2218), but the wind is cross-shore in the morning and cross-onshore in the afternoon. The long period might make it a bit tricky here, but there will be plenty of power.
Thursday, August 6th, is an absolute standout. The swell is 6.2ft from the SSW at 17 seconds, with a light cross-offshore breeze from the NNE in the morning and glassy conditions in the afternoon. The energy is huge (2193). This is excellent for experienced surfers only – the power is serious, and the reef will be working hard.
Friday, August 7th, keeps the quality going. Another 5.9ft to 5.2ft SSW swell, clean conditions with light cross-offshore winds all day. Energy is still very strong (1827-1880). This is still expert territory.
Saturday, August 8th, is the big one. The swell hits 6.6ft to 7.5ft from the S, with a 20-second period. The energy is extreme (3934-4717). The wind is a clean cross-offshore from the SE. This is for experts only – the size and power are serious. If you’re not solid, sit this one out. The reefs will be handling a massive, long-period groundswell.
Sunday, August 9th, the swell is still 8.2ft, but the wind picks up to a moderate breeze. The conditions get a bit wind-affected, but the energy is still extreme (4252). This is still big and powerful, but the wind will put a bit of texture on the face.
Monday, August 10th, through Tuesday, August 11th, the swell drops from 7.2ft back to 5.6ft, but the wind stays a moderate cross-offshore breeze. The conditions are still clean, but the energy is dropping from 2447 to 1483. The quality is there, but the size is backing off, and the wind is a bit stronger, so it won’t be as perfect as the earlier days.
Overall, the best on offer is Saturday, August 1st, and Thursday, August 6th, for the glassy, powerful, clean conditions. For the biggest, most powerful swell, Saturday, August 8th, is the pick, but it’s

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.
