Local Environmental Conditions
This area, close to home here, has the riverbank shelters river oak, whose pollen spreads readily on the wind from spring onward. Woodland where eucalypt stands alongside wattle, the latter especially aggressive as an allergen when in full flower; this sits within the neighborhood. Located within easy reach, this area has green space with maintained lawn and planted plane trees, both contributing to seasonal pollen counts.
River oak along the water gets the season underway before other species, topping out well before most other trees start releasing pollen, around July and August. By late winter, eucalypt and wattle in the woods take over, usually peaking from August into October. Through spring, grass pollen climbs steadily toward its November peak, holding through the summer months before tapering off by late February.

Does pollen in Spearwood 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 Spearwood 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 Spearwood, 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. |
