Perth sits on the Swan Coastal Plain, where banksia woodland, tuart and jarrah forest and kwongan heathland provide the dominant native vegetation, interspersed with parks and street plantings of both native and introduced trees. Wattle is widespread and flowers heavily through late winter. The sandy coastal soils support quite different vegetation to the clay-based Darling Range foothills further inland.

When is pollen season in Perth?
Perth's pollen season is concentrated between August and November, driven by its Mediterranean climate of mild, wet winters and long, dry summers. Tree pollen, from both native eucalypts and introduced species, typically opens the season in August-September, with grass pollen from the Swan Coastal Plain's pastures, parks and verges peaking through October and November. The dry summer that follows sharply suppresses further pollen activity, giving Perth a shorter, more intense season than subtropical cities further north.
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.
