Local Environmental Conditions
Open water and built-up land share the area around the center of São Francisco do Sul, plus some woodland. Woodland on all sides makes trees an important local pollen source. Grass pollen is a substantial part of the local mix as well. Local vegetation is sparse, so most pollen arrives on the wind from surrounding land.
Flowering trees bring the first pollen of the year in early spring. Grasses take over in mid-spring, with temperatures around 20°C, and their pollen lingers into mid-fall. A smaller weed peak follows from early summer into early fall. Mold spores are in the air most of the year too, rising after rain.
