Local Environmental Conditions
Around 46% of the area near the center of Jacksonville, North Carolina is open water, with a good deal of woodland. With Water Creek nearby, riverside vegetation along its banks contributes to the local mix. Trees are an important local pollen source, given how much woodland surrounds the area. Pollen also travels on the wind, so vegetation in the wider surroundings adds to local levels as well.
Flowering trees bring the first pollen of the year in early spring. Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. In warm, humid weather from mid-spring into mid-fall, mold spores add to the mix, especially after rain. Within each of these periods, warm, dry and windy days push levels higher, while rain clears the air.
