What they say about our waves:
here are some comments from our guests or the internet.
" The waves aren't the dramatic, over-powered explosions of winter Hawaii, or the almost supernatural, curving menace of southwest Tahiti. They're silky, perfectly formed and balanced. They swing among the islands in a refracted dance around deepwater reefs and tidal channels, and bend into quick, delicate shapes. The water is 28ºC. It's probably the best surf in the world.
" The Mentawai islands Archipelago offers waves among "the planet's most perfectly shaped waves ever" and is "one of the most consistent surf destinations in the entire world". "More than a dozen worldclass reefbreaks exist making it one the most surf infested regions in the world". On a total of about 60 waves for the entire Archipelago, 30 situated 10 to 20 minutes speed-boat ride from Siloinak Resort.

4 Bobs
A right, fun, short and mellow wave for all surfers. Pretty mellow drop with the opportunity for one whack at the lip and then it mushes out into deep water. It can get a bit shallow at low tide so you need to watch yourself but all in all, it's one of the most rippable alternative's in the Mentawai's.
A Frame
A Frame is one of the most consistent lefts in the Mentawai Islands. The peaks at the top can be a bit shifty and require a fair amount of paddling around to find the right area while the inside section is more dependable and offers up a better wall to work with.
Bankvaults
A thick, tricky, shifty right with a fast and intense tube for experienced surfers only, near Nipussi. Think heavy steel doors, secret unlocking combinations and burly guards with smack-down attitude. Usually larger than most spots in the area. Watch out for clean-up sets.
Beng-Beng
A very consistent world class wave, an extremely rippable left. This spot is loads of fun and probably one of the easiest waves to surf in the Mentawai's. It's the deepest and safest wave in the area and also pick up a bit more swell than other locales. 5 more breaks in the area, including E-Bay and Pitstops. Nestled inside a small bay with one of the most scenic views imaginable all around you.
Burgerworld
The last possibility when the Ments are flat (it does happen, in spite of what says the legend! But, true, it's rare). A right hander with long rippable walls and many cutback sections. For intermediate surfers. Beautiful jungle.
E-Bay
A holow, fast, powerful left. A world class wave for experienced surfers. Watch out for the two rocks on the inside. Great barrels, and turns into a surfing paradise at 6 feet offshore. There is a heavy warble that hits as you are taking off. Make the drop and don't get thrown by that first warble and chances are you'll get a mean aqua blue barrel. The scenery alone will blow you away. Besides its aesthetic beauty, double overhead E-bay is a beast and forces to be reckon with.
Hideaways
One of the best waves in the Mentawai's when it's working, which doesn't happen everyday… This very hollow left-hand comes out of deep water, then unloads on a shallow section of reef before barreling towards the channel. Can get very shallow at low tides.
Kandui Left (Nokandui)
A long barrelling left, Incredibly fast and powerful. If you have watched the OP Billabong Pro 2001 video or any of the Taylor Steele flicks you have seen this place. Pretty epic, but really tough when it's bigger. An upgraded version of G-land. Advanced to Expert surfers only. One of the very rare crowded waves in the area.
Kandui Right (Rifles)
This right is considered by some to be the best waves in the Mentawai Islands, and sometimes the world, when ideal conditions prevail. This is a temperamental right-hander's, insanely hollow once it’s a few feet overhead, with multiple, violent barrel sections. Up to four to six hundred yard walls. You have to go as fast as you can go almost the whole way through the wave. You can take off anywhere down the line and still get the best wave imaginable. For Advanced to Expert surfers.
Nipussi
A shorter right that breaks down the point from Bank Vaults. Like Burgerworld, Nipussi always has waves. It's the most consistent spot around here. Easy and yet powerfull.. Beautiful location.
Pitstop
A playful high performance right, near E-Bay. Starts breaking over reef, with a tricky take-off, breaks over sand until a superb beach. One of the most photogenic waves in the world. Chances to meet film crew or professional photographer at work here.

Here is a list of the best known swell and weather forecast websites covering the Mentawai Islands.

NOAA Wave Period Animation
Same, but for the swell. The longer the wave period the best the surf in the Mentawai.
Wetsand
Indonesian surf reports on the internet. Wave height, period, wind, and tide.
METEOSAT-5: Enhanced Satellite Image
Practically the same animation as above but in an easier to read enhanced color format. This satellite enables you to see clouds and precipitation a lot easier than the original.
