Telescopes is a Mentawai gem—a long, wrapping left-hander that offers 200+ meter rides through multiple barrel sections. The wave starts with a steep, hollow drop before transitioning into workable shoulder sections that allow for endless speed generation. Located in North Sipora, it thrives on W-SW swells and the typical SE trade winds. It's one of the most user-friendly quality waves in the Mentawais, making it popular with intermediate-advanced surfers looking for tropical perfection.

Telescopes is a reef break in North Sipora, Mentawais, Indonesia, that mostly breaks left. It's on our list of the world's 100 best waves.
Telescopes breaks off northwest Sipora alongside Iceland and Scarecrows. Sipora is also home to Tuapejat, the regency capital of the Mentawai Islands.
Telescopes picks up swell from the SW round to the W, and it's best when it's coming straight out of the WSW. That's a tight window, so it needs the swell direction to line up. It starts working at around 0.9m and handles up to about 3m, with the sweet spot around 1.8 to 2.5m. Period matters too: aim for 16s or longer, as anything under 14s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.
An ESE wind is dead offshore at Telescopes, and anything from the ENE round to the SSE keeps it clean. The morning is typically the best window, roughly 6am to midday. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.
Telescopes isn't especially fussy about tide and generally works through the cycle, so swell and wind matter more here. Big tides can still change how it breaks, so it's worth checking before you paddle out.
The most reliable run of swell at Telescopes comes Apr to Oct. There's a second window in Mar and Nov too. 74% July clean.
It's more of an intermediate wave, rated 6/10 for difficulty, so newer surfers are best off sticking to the smaller days. The lineup is usually quiet (crowd 3/10). Things to watch for: shallow water at low tide and sharp, shallow reef (booties help).
The nearest airport on our list is PDG. From there you need a boat to reach the break (we estimate around $250 USD, but confirm with an operator). Boat/resort.
The closest breaks we track are Seven Palms (0.6 km), Scarecrows (1.0 km) and Icelands (1.1 km), handy when Telescopes isn't working.
