It was studied the influence of the land-sea breese on the duration of relative humidity equal to or higher than 90% (NHUR > 90%) inside two adult rubber tree plantations [Hevea brasiliensis (Willd. ex Adr. de Juss) Müell Arg.]: one located near the shore (800 m) and other approximately 5,000 m away. It was found a significant reduction of NHUR > 90% in the plantation near the shore. This reduction was even more evident in clear nights, without rainfall effect. It is assumed that the advection of land-sea breese interferes at the starting and final moments of the humidity saturation, decreasing the leaf wettness duration period.
