Generally we anchor well away from land and mosquitoes but we strongly recommend that you play it safe. Trading in the islands requires small Rupiah denominations. Bring your own mixers. No corkage charges. The Mentawais get surf all year round but in common with Bali, the biggest and most consistent surf hits the islands in mid April and backs off in late October.
Winds are light and variable most of the year.
During April to October SE to SW winds favor the left hand breaks and NW to W winds for the balance of the year favor the rights. The Mentawais are very very consistent but the Indian Ocean is running the show and there is not much we can do. We have some special spots that break in the slightest ground swell so bring a short board for mini barrels in crystal clear water. Expect lots of thunderstorms with squalls for short periods of time followed by calm. Take a break and have a warm rain shower.
