Derby, on the tidal mudflats of WA's West Kimberley, experiences a tropical monsoonal pollen season with pollen activity concentrated in the dry season from May to October. Grass pollen from surrounding savanna and pastoral land builds steadily through these months, while tree pollen from paperbark, eucalypt and acacia species tends to open toward the end of the dry, roughly August to October. The wet season from November to April brings heavy rain and cyclone risk that largely washes pollen from the air until the cycle repeats.

The Derby 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 Derby, 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.
