Local Environmental Conditions
Waterfront precinct on Bunbury's inner harbour, where foreshore plantings mix coastal peppermint (Agonis) and eucalypt with Norfolk Island pine and other ornamental shade trees along the promenade. Estuarine wetland fringes nearby carry paperbark and samphire. Onshore sea breezes off Koombana Bay generally disperse pollen, but spring peppermint-tree and eucalypt flowering plus coastal wattle bloom still register in the local air.
Koombana Bay's coastal marina setting in Bunbury brings onshore breezes that moderate the Mediterranean southwest's pollen season, wattle flowering from August and grass pollen from foreshore parks and reserves peaking September-October. Being right on the water, the bay typically sees milder counts than Bunbury's inland suburbs before the region's hot, dry summer closes the season down. The marina precinct's newer plantings add a modest further tree pollen contribution alongside the foreshore parks.

How often is the Bunbury pollen forecast updated?

Does pollen in Bunbury 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 Bunbury 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 Bunbury, 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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
