Local Environmental Conditions
The landscape around the heart of Berowra Heights is heavily wooded. Close to a watercourse, riverside vegetation contributes to what is in the air. Woodland on all sides makes trees an important local pollen source. Grasses also feature strongly, alongside pigweed and plantain among the weeds. Clearings, tracks and woodland edges let grasses and other flowering plants grow among the trees.
Tree pollen comes first, peaking in late winter. Then come the grasses, strongest in mid-spring and fading by early fall. Pigweed and plantain bring a final peak from early summer into early fall. Fall is the wettest time of year, and heavy showers can bring short breaks in pollen. Within each of these periods, warm, dry and windy days push levels higher, while rain clears the air.

Does pollen in Berowra Heights come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. 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 Berowra Heights 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 Berowra Heights, 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.
