Local Environmental Conditions
The area around this part of Penrith is mostly woodland, with a good deal of open grassland and some built-up land. Close to a stream or river, riverside trees such as plane tree contribute to what is in the air. Among allergenic trees nearby, plane tree is the main source. Grasses and weeds such as pigweed and plantain round out the local mix.
Tree pollen peaks in late winter, when the weather warms to around 10°C and plane tree is in full flower. Grass pollen follows, peaking in mid-spring and easing off by late summer. The season closes with pigweed and plantain from early summer into early fall. Fall is the wettest time of year, and heavy showers can bring short breaks in pollen.

Does pollen in Penrith 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 Penrith 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 Penrith, 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.
