Coffee producers face more crop-damaging heat, analysis says

A Climate Central analysis finds top coffee-producing countries are experiencing an average of 57 extra days per year of heat damaging to coffee plants, with Brazil seeing about 70 extra days and Colombia about 48. Farmers report harvest losses and market pressures as production and bean quality are affected.

A new Climate Central analysis reports that coffee-growing regions are experiencing more days of heat that experts say harm coffee plants, and growers are reporting harvest losses and other pressures. The study compared current temperatures to modeled temperatures without human-caused climate change and flagged temperatures above 30 C as damaging for coffee. Producers across major coffee countries including Colombia and Brazil are cited, and some farmers say losses have been substantial in recent years. The story is being discussed because changes in yield and quality affect smallholder livelihoods and global coffee supplies. Key findings: - Climate Central calculates an average of 57 extra days per year of coffee-damaging heat across the world's top coffee-producing countries. - Brazil is reported to experience about 70 extra damaging-heat days per year, and Colombia about 48 extra days. - Farmers cited in the report describe large harvest losses, including examples of more than half a harvest lost in a recent year. - Statistics Canada data cited in the article notes retail prices for roasted or ground coffee were 37.4% higher in January 2026 than a year earlier. Summary: The analysis indicates a widespread increase in heat stress that can reduce coffee yields and affect bean quality, placing pressure on many smallholder producers. Undetermined at this time.
