Mandiri Beach is possibly the best beach break in all of Indonesia, producing triangular peaks that detonate with thick barrels on the sandy bottom. Located in the Krui region of South Sumatra, it works best during off-season or smaller swells when the sand banks are well-formed. The morning offshore winds create perfect conditions for barrel hunting on shifting peaks. A rare gem for beach break enthusiasts in a country known for its reefs.

Mandiri Beach is a beach break in South Sumatra (Krui), Indonesia, with peaks that run both left and right.
Mandiri Beach picks up swell from the SSW round to the WSW, and it's best when it's coming straight out of the SW. 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 1.8m, with the sweet spot around 1.3 to 1.6m. Period matters too: aim for 12s or longer, as anything under 8s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.
A NE wind is dead offshore at Mandiri Beach, and anything from the NNE round to the ENE 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.
Mandiri Beach 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 Mandiri Beach comes Apr to Oct. There's a second window in Nov to Mar too. Best Apr-Oct (dry season, SE trades offshore). Swells year-round but wet season brings onshore winds.
The water at Mandiri Beach averages around 28°C, so boardshorts or a rashguard will do. It shifts a few degrees through the year, so check the season before you pack.
It's more of an intermediate wave, rated 6/10 for difficulty, so newer surfers are best off sticking to the smaller days. Expect a moderate crowd (4/10) when it's on. Things to watch for: sharp, shallow reef (booties help).
The nearest airport on our list is TKG, then it's roughly a 4-hour drive. Drive from Bandar Lampung (~6hr).
