In which climate zones is sugarcane grown most successfully?

Sugarcane is most successfully grown in tropical and subtropical regions. While the plant is adaptable to various environments, it requires specific thermal and moisture conditions to thrive.

The ideal temperature for sugarcane growth is approximately 20 °C (68 °F) or higher. Because the plant is sensitive to cold, continuous cooler temperatures are generally avoided during the primary growth phase, though they are useful later to promote maturation.1

Regarding water requirements, sugarcane demands significant precipitation, typically needing 2,000 to 2,300 mm (80 to 90 inches) of water throughout its growing period. In areas where rainfall is insufficient, irrigation is necessary to maintain yields. The crop is cultivated in diverse locations ranging from maritime subtropical climates, such as Mauritius, to various regions across Australia, Hawaii, and South Africa, with growth cycles adjusted based on the specific local climate.1
