Coffee is one of the world's most climate-sensitive crops, and weather patterns are moving against growers. Temperatures above 30°C harm arabica, the world's dominant coffee species. Between 2021 and 2025, the five countries that make up 75 percent of global coffee production saw 57 additional days of coffee-harming heat on average, according to independent research group Climate Central.
The problem extends beyond heat alone. Brazil faced hailstorms and floods last year. Vietnam has battled floods and persistent rain. Any sharp weather swings bring production stress.
The speed of change
What worries industry players most is the pace of disruption. Oliver Broster, senior manager of coffee analysis at Expana, notes that anomalous weather events once arrived roughly once every 10 years. In the last five years, the industry has seen three such events. That compression creates unpredictability in supply, demand, and stock levels, which cascades into procurement headaches and supply-chain strain.
Colin Hall, co-founder of UK premium-coffee brand Cupper's Journey, describes the shift bluntly: "Weather patterns are becoming far less predictable, with longer dry periods, shifting rainfall and more extreme weather events affecting harvests and crop quality." Unexpected weather events also create concerns about soil health and water availability, adding financial pressure on growers.
Price swings and producer survival
The volatility feeds directly into coffee prices, which have experienced sharp ups and downs. While tariffs and global supply disruption play a role, weather is the biggest driver of price movement. That instability makes procurement harder and destabilizes the coffers of producers who lack financial buffers.
Adaptation paths
Coffee brands and producers are exploring multiple routes to adapt. Direct relationships with growers, transparent pricing, and fair-trade certification that emphasizes climate resilience are emerging as core strategies. Agronomic support, regenerative farming practices, water-management systems, and climate-resilient crop strategies can help growers build resilience.
Robusta, a hardier coffee species than arabica, is gaining ground. Uganda has invested in robusta expertise and is now thriving with a more resilient crop. Rediscovering wild coffee species, neglected for decades in favor of robusta and arabica dominance, could offer new climate resilience and disease resistance, or allow farming in previously unsuitable areas.
