The nearby nearby reservoir adds further grass and tree pollen exposure, particularly under onshore breezes. On top of that, birch and rowan are the two species driving most tree pollen in Perth, especially around parks and green corridors. Seasonal peaks tend to track the wider regional pattern, tree pollen leading in spring and grass through summer.

How often is the Perth pollen forecast updated?
The Perth pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Perth 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 Perth 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 Perth, 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.
