How far can spray drift move?
Fine spray droplets can move for many miles under the right conditions. They move farthest during temperature inversions (night or early morning) because high humidity keeps them from evaporating and calm air keeps them from dispersing. Topography is also important, as drift will follow low-lying areas. Windy conditions actually help disperse the spray. When it’s windy, a greater proportion of the spray will drift, but it also gets diluted rapidly.
