The Short Version
Indonesia’s coffee output will drop 8% as heavy rains and El Niño disrupt harvests, threatening both yield and quality. Exports face an 11% slump, with domestic demand struggling to keep pace amid climate-driven challenges.
Indonesia’s coffee output faces an 8% decline as persistent rains and El Niño conditions disrupt the harvest. The USDA FAS report highlights that excessive rainfall in southern Sumatra and Java has already damaged flowering and fruit development, while a weak El Niño is exacerbating drought risks. For farmers, this means fewer beans—and a race to salvage what remains.
Excessive rainfall and El Niño conditions are disrupting Indonesia’s coffee harvest, pushing output down 8%.
Weather Wreaks Havoc on Robusta and Arabica
The 2026/27 forecast hinges on a climate-driven reckoning. Southern Sumatra and Java, which account for 80–90% of robusta output, saw flowers fall and pollen washed away in the wake of Tropical Storm Sinyar. Flooding in Aceh and North Sumatra damaged 12,000 hectares of plantations, delaying recovery for years. As coffee area remains stable, the El Niño-driven dry season is set to intensify the crisis, threatening both yield and quality.
Exports Slide, Domestic Demand Stalls
Green coffee exports are projected to drop 11% to 7 million bags, with Europe’s rising demand failing to offset shrinking supplies. The U.S., a top market, still takes 60–80% arabica beans, but higher green prices have pushed consumers toward cheaper blends. Kopi susu remains popular, but roaster margins are under pressure. Domestic consumption is expected to rise marginally, yet climate challenges are outpacing growth, leaving processors scrambling to adjust.

Questions & Answers
How is Indonesia's coffee output expected to change due to climate challenges?
Indonesia’s coffee output is projected to decline by 8% due to persistent rains and El Niño conditions disrupting the harvest. Excessive rainfall in southern Sumatra and Java has damaged flowering and fruit development, while a weak El Niño is increasing drought risks, threatening both yield and quality.
What impact will climate challenges have on Indonesia's coffee exports?
Climate challenges are set to reduce green coffee exports by 11%, to 7 million bags. Europe’s rising demand cannot offset shrinking supplies, and higher green prices have pushed consumers toward cheaper blends, putting pressure on roaster margins and export volumes.
Why are farmers in Indonesia struggling with the current harvest conditions?
Farmers are struggling due to excessive rainfall and weak El Niño conditions that have damaged coffee crops. Tropical Storm Sinyar washed away flowers and pollen in Sumatra, while flooding in Aceh and North Sumatra destroyed 12,000 hectares of plantations, delaying recovery for years.
How are domestic coffee markets in Indonesia affected by climate challenges?
Domestic coffee consumption is expected to rise marginally, but climate challenges are outpacing growth. Despite the popularity of kopi susu, processors are scrambling to adjust as climate disruptions threaten both supply and quality, impacting roaster margins and market stability.
