Appearance
LESTE, a desert wind, similar to the Leveche (q.v.), observed in Madeira. It blows from an easterly direction in autumn, winter and spring, rarely in summer, and is of intense dryness, sometimes reducing the relative humidity at Funchal to below 20%. The Leste is commonly accompanied by clouds of fine red sand.
