The Lowdown
Alright folks, Rusty here. Let’s have a look at the coming weeks for Telescopes. We’ve got a bit of a slow start, but the second week is shaping up to be something special. The water’s sitting at a warm 86° here, which is a touch warmer than normal for this time of year.
The first few days are pretty marginal. Wednesday and Thursday the 22nd of July have some waist-chest high swell from the SSE, but the wind is a cross-offshore breeze, so it’s clean but not pushing much energy. The combined energy is moderate (419 to 779). The wave comment says it’s marginal, so don’t expect much. Friday the 24th through Sunday the 26th are similar, with swell holding around 5ft to 6ft, but the wind is cross-off and the energy is moderate (680 to 823). It’s clean, but the quality isn’t quite there for a standout.
Monday the 27th and Tuesday the 28th see the swell drop right down to 2ft to 3ft, but the wind goes glassy on Tuesday. That’s pretty, but you’ll be on a longboard or a foamie. The energy is weak (302 to 346). Then Wednesday the 29th through Friday the 31st, we get a sweet run of small but very clean waves. The swell is tiny, 2ft to 4ft, but the period jumps up to 14-21 seconds, which is proper groundswell. The energy is moderate to strong (397 to 950). The wave comment says “very good surf conditions,” and that glassy wind on the 30th morning is a major positive. The swell direction is SSW, which is right in the sweet spot for this reef. However, it’s small, so not a standout for size.
Now, the real gold is in the first week of August. Saturday the 1st is a bit of a write-off with cross-onshore wind, but Sunday the 2nd and Monday the 3rd glass off again. The swell is 4ft to 4ft from the SSW, with a long period of 14-16 seconds. The energy is strong (785 to 952). It’s clean, but the size is still modest.
Then, mark your calendars for Tuesday the 4th and Wednesday the 5th of August. This is the standout. The swell jumps to 6ft to 7ft from the SSW, with a very long period of 17-18 seconds. The combined energy is massive (2182 to 2595), which is strong to very strong. The wind is glassy or light offshore from the east and northeast. That is a recipe for perfection at Telescopes. The wave comment says “excellent surf conditions for experienced surfers,” and honestly, that’s the understatement of the year. This is a proper groundswell, so the reef will handle it beautifully. It’s a bit over 5ft, so it’s not a beginner wave, but for the experienced crew, this is the best on offer. Thursday the 6th sees the swell hold at 7ft, but the wind turns light cross-shore and cross-onshore, so it gets a bit messy.
So, the best on offer is without a doubt Tuesday the 4th and Wednesday the 5th of August. Glassy, powerful, long-period SSW groundswell at 6ft to 7ft. It’s an advanced wave, but it’s a dream. The crowds can be there sometimes, but honestly, for this quality, it’s worth the paddle.
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.
