On Melbourne's volcanic outer-northern plains, pollen season runs August to January, with eucalypt and wattle flowering in late winter followed by rye grass across the surrounding grassy plains peaking October to December. The open volcanic grassland typical of this growth corridor means spring winds can carry substantial grass pollen loads even as new housing estates replace paddocks.

The Sunbury 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 Sunbury, 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.
