Local Environmental Conditions
Woodland makes up around 43% of the area near the heart of Ottawa, with a good deal of built-up land and open grassland. Close to the Cygnes River, riverside vegetation adds to local tree pollen. Trees are an important local pollen source, given how much woodland surrounds the area. Grass pollen is a substantial part of the local mix as well.
Flowering trees bring the first pollen of the year in mid-spring. Grasses take over in late spring and keep pollen in the air into early fall. A smaller weed peak follows from early summer into early fall. Spring is the wettest time of year, and heavy showers can bring short breaks in pollen. By late fall, as temperatures fall to around 5°C, pollen levels are low again.
