Local Environmental Conditions
The landscape around this location in Lower Portland is heavily wooded. The damp ground beside a stream or river nearby supports trees, shrubs and reeds, adding to local pollen. Woodland on all sides makes trees an important local pollen source. Grasses are also a significant pollen source here. Undergrowth, clearings and woodland edges add smaller amounts of grass and herb pollen.
Flowering trees bring the first pollen of the year in late winter. Grasses take over in mid-spring and keep pollen in the air into late summer. Weeds on open ground add a smaller late peak from early summer into early fall. Fall is the wettest time of year, and heavy showers can bring short breaks in pollen.

A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Lower Portland based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Lower Portland, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
