While cocoa trees can grow outside of this zone, they will not grow as well. For cocoa trees to grow best, warm-to-hot temperatures all year (in the range of 65 to 90 degrees F) are required. Constant high humidity and a good deal of rainfall (usually 40 to 100 inches per year) are necessary, as well. The cocoa trees grow poorly in wind, any kind of cold, or drought. Cote d’Ivoire, Ghana, and Indonesia have ideal conditions for growing cocoa trees, and these three countries produce more cocoa beans than anywhere else.
