Local Environmental Conditions
Distinctive pink granite monolith overlooking the city, its lower slopes carrying dry eucalypt woodland and spinifex-grassland pockets typical of the region's savanna, with acacia and native grasses colonising rocky outcrops. Surrounding suburban streets mix shade trees like poinciana with mown lawns. The exposed, elevated aspect promotes wind dispersal of savanna eucalypt and grass pollen, especially during the buildup and early wet season.
Castle Hill's landmark red rock rising over inner Townsville gives the surrounding suburb a somewhat drier microclimate than typical tropical coastal towns, with grass pollen from the district's parks building through the dry season from May to October, and tree pollen from eucalypt and paperbark opening later in the dry, around August-October. Townsville's comparatively lower rainfall than Cairns further north means the wet season here is a little less dominant, giving the dry-season pollen build a clearer run.

How often is the Townsville pollen forecast updated?

Does pollen in Townsville 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 Townsville 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 Townsville, 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. |
