This paper investigates the discrepancy between the "calendar spring" (beginning September 22/23) and "climatological spring." Through an analysis of historical temperature data, precipitation trends, and the "Indian Summer" phenomenon ( Veranico ), we propose that spring in Brazil is not a uniform date, but a gradient phenomenon beginning as early as late July in the Central-West and extending into October in the Southern Cone.
