Indonesia
The richest surf country on earth
Ask surfers to name the richest surf country on earth and most of them will land on Indonesia. The archipelago stretches more than 5,000 kilometers along the edge of the Indian Ocean, and for months on end the mechanics barely change: long-period groundswell marches up from the Roaring Forties while the dry-season southeast trade winds blow offshore, day after day, onto reefs that seem shaped for exactly this. No other country turns so much open ocean into so many perfect waves.
The calendar is the first thing to learn. The reliable season runs April to October, when the trades groom southwest swell on every exposed coast; there are real waves year-round, but the wet season, November to March, flips the wind and sends the smart surfers to the opposite-facing coasts. The geography then sorts itself into three chapters: Bali, the gateway, where world-class reef sits beside a road; the Mentawais, a jungle archipelago off West Sumatra reached by boat; and Lombok and Sumbawa, the drier islands east of Bali where the crowds thin with every ferry.
Choosing is mostly a question of effort. Bali is the easy first trip: flights land in Denpasar, every level finds a wave, and the variety within an hour on a scooter is almost absurd. The Mentawais are the trip of a lifetime, by charter boat or land camp, for surfers ready for serious reef. Lombok and Sumbawa reward whoever drives further, with Desert Point and Lakey Peak at the end of the road. And wherever you land, the day is decided by the forecast, not the map: SurfMap tracks conditions on more than 5,000 spots, so the reef in front of you is in your pocket.

Bali
The gateway. From Uluwatu's cliffs to Canggu's rivermouth peaks, more world-class surf sits beside a road here than anywhere else, with temples above the lineups and warm water in every season. Beginners get sandy Kuta, experts get the Bukit's barrels, and the wet season simply moves everyone to the east coast.

Mentawai Islands
The boat-trip and camp archipelago a hundred miles off West Sumatra, and by wide agreement the densest collection of perfect reef waves anywhere: HT's, Macaronis, Rifles and dozens more, stacked within sight of each other. It takes a flight to Padang and a crossing, and it repays every hour of the journey.

Lombok & Sumbawa
The drier islands east of Bali, where the lineups get honest again. Lombok's south coast is a string of horseshoe bays, with Desert Point, routinely called the best left in the world, around the corner; one ferry further, Sumbawa hides Lakey Peak's playground and kilometers of empty reef. More effort, fewer people.

Good to know
When is the surf season in Indonesia?
The reliable window is the dry season, April to October, when southeast trade winds blow offshore on the exposed coasts and long-period groundswell arrives from the southern Indian Ocean week after week; June to August is the heart of it. The wet season, November to March, does not mean flat: the swell keeps coming, the wind flips, and the coasts that face the other way, Keramas on Bali's east side for example, take over. It means smaller averages, warm rain and far fewer people.
Which region of Indonesia should I pick?
Bali for ease and range: direct flights, every level within a scooter ride, and an offshore coast in both seasons. The Mentawais for the trip of a lifetime, by charter boat or land camp, if you are a solid intermediate or better and reef surfing does not scare you. Lombok and Sumbawa for fewer people and long lefts: more driving and ferries, and the reward is Desert Point, Lakey Peak and bays you may share with nobody.
Do I need a boat trip to surf Indonesia?
Only for the Mentawais, really: the islands sit a hundred miles off Sumatra, and you reach them by charter boat or by a fast ferry to a land camp. Everywhere else is a land trip. Bali is scooters and roadside cliffs, Lombok and Sumbawa are a rental car, a couple of ferries and the occasional outrigger across a bay. Plenty of surfers have had the trip of their lives in Indonesia without ever sleeping on a boat.
