Perth's pollen season follows the Southern Hemisphere spring pattern, running from August through December. Tree pollen from eucalyptus and acacia opens the season in August and September, with grass pollen peaking through October and November. The Mediterranean climate means the season is concentrated in a relatively short spring window, with the long, hot, dry summer from December to March largely suppressing late season pollen exposure.

The Perth pollen forecast is updated four times daily. See the timestamp below for the most recent update.

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.

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.
