The macadamia nut has a growing market with great potential, but still little explored in Brazil. The regional climate and soil conditions have extreme importance to crop sustainability exerting great influence on phenology, quality and productivity. The aim of this study was to make the agroclimatical zoning of macadamia nut to Brazil. For this purpose, information about the relationship of climate requirements and plant development were used to establish classes of capability and subsequent mapping of suitable, marginal and unsuitable regions for nut production. Mean air temperature and precipitation data from 1073 Brazilian weather stations were used. Each station had at least 30 years of data. As a result São Paulo, Rio de Janeiro, Espírito Santo, southern Minas Gerais, eastern Mato Grosso do Sul, and west of Paraná had favorable conditions for macadamia nuts cultivation.
