Coffee Is Kind of a Diva About Weather
The short version
- Arabica is picky. It wants cool, steady highland weather, and climate change is shrinking the places that have it.
- One big study says hotter, drier regions like parts of Brazil and Central America could lose almost 80% of their arabica land by 2050.
- Weather in big coffee countries moves global prices. Brazilian drought helped push arabica to record highs in early 2025.
- Shade trees and healthy soil are some of the best tools farmers have.
Let me tell you about the biggest diva in agriculture. It’s not avocados. It’s not wine grapes. It’s arabica coffee.
Arabica, the species behind basically every specialty coffee, wants cool nights. Steady rain. A proper dry season. Absolutely no frost. Bump the temperature a couple degrees or stretch the dry season a few weeks and it throws a full tantrum. Yields drop. Quality drops. Pests and disease move right in. High maintenance doesn’t even begin to cover it.
Where coffee can grow is moving
In 2015, scientists at the International Center for Tropical Agriculture (CIAT) and World Coffee Research mapped how climate change could shift arabica-friendly land. Published in PLOS ONE. Here’s what they found:
- Hotter regions with long dry seasons, including parts of Brazil and Central America, could lose almost 80% of their arabica land by 2050.
- Even cooler highlands in East Africa, Colombia and Indonesia could see about a one-third drop.
- Around 25 million farmers grow arabica. Most of them are small family farms.
Is that set in stone? No. Farmers adapt. Breeders are working on tougher varieties. But the direction is obvious. Growing great coffee is getting harder.
Why Brazil’s weather hits your morning
Brazil grows more coffee than anybody on Earth. When Brazil sneezes, the whole market catches a cold. Drought in Brazil plus bad weather in Vietnam helped send arabica futures to record highs above $4.40 a pound in early 2025. This year, Brazil had a record harvest and prices dropped back toward $3. Then El Niño-linked humidity and rain showed up during drying and everybody started worrying about bean quality. One country. One season. A dollar a pound swing. Insane. (We track it every month in the Coffee World Roundup.)
What helps farms hang in there
- Shade. Trees keep the coffee cooler, hold humidity, and block heavy rain and wind. Smithsonian research also found farms with more complex vegetation had way fewer hurricane-triggered landslides.
- Living soil. Soil full of organic matter holds water through dry spells. Unshaded Nicaraguan farms saw water soaking into the ground drop by up to 75% in under a decade. (Dirt is very important.)
- Don’t put all your eggs in one basket. Farms that also grow fruit, timber or other crops have a backup plan in a bad coffee year.
- New varieties. Breeders are testing coffees that handle heat and disease better.
Weather is the one thing a farmer can’t control. Shade and good dirt are how they fight back.
Our Nayarit coffee comes from one farm in El Cuarenteño, grown under shade and roasted every week in North County. It’s good. You should try it.
