Local Environmental Conditions
Around 35% of the area near the center of Salem is woodland, with a good deal of built-up land and some wetland. With the Delaware River nearby, riverside vegetation along its banks contributes to the local mix. In the immediate area, the woodland makes trees an important source. Street trees, private gardens and mown lawns add to local pollen in the more built-up surroundings.
Flowering trees bring the first pollen of the year in mid-spring. Grass pollen follows, peaking in late spring and easing off by early fall. By early winter, as temperatures fall to around 5°C, pollen levels are low again. Actual levels on any given day depend on the weather, with dry, breezy days the worst and wet days the mildest.
