What is the best climate to grow sugarcane?

Sugarcane is considered essentially a tropical plant. It is a long-duration crop and thus it encounters all the seasons: rainy, winter, and summer during its life cycle. The sugarcane plant grows best in tropical hot sunny areas. The ideal climate for the production of maximum sugar from sugarcane farming is characterized to:

• A long, warm growing season with a high incidence of solar radiation and adequate moisture (rainfall) - the plant uses from 148 to 300 G of water to produce 1.0 G of dry substance.
  

• A fairly dry, sunny, and cool, but the frost-free season for ripening and harvesting - moisture percentage drops steadily throughout the life of the sugarcane plant, from 83% in very young cane to 71% in mature cane, meanwhile, sucrose grows from less than 10 to more than 45% of the dry weight.
