Agroforestry (AF) and full sun (FS) agroecological systems with coffee, which were set down by smallholders in Zona da Mata de Minas Gerais, have not been studied for water economy and temperature. This study evaluated these factors for these systems. Neighboring AFs and FSs systems were selected in Araponga-MG. During 16 months were hourly monitored: rainfall, wind speed, radiation, air moisture, air temperature, soil temperature at 0,1 m, soil water content at 0,1 m, 0,3 m and 1,0 m with reflectometers and soil and water surface loss joined with soil cover. Soil and water loss of both systems were small due to the high soil cover. Soil temperature was depressed under AF system. Air temperature under AF had less variation than under FS and lower maximum temperatures. Soil moisture of AF was lower than FS for all depths in all monitored period. There was water absorption complementarity between coffee and trees in AF system. AF and FS systems may be used to manage the destiny of rainfall water, mainly for atmosphere in the first and deep drainage in the second.
