Local Environmental Conditions
Here, near this part of town, eucalypt dominating the treeline with wattle scattered through it, both contributing to the season's pollen load. Ground-level conditions like local landscaping can nudge these figures slightly either way. Nearby weather stations report comparable trends across the broader stretch of the region. Small shifts in elevation or soil type can move these figures a little either way.
The woodland's eucalypt and wattle trees become the main pollen source as wattle flowers, typically landing in August and September. Grass pollen counts rise through spring, reaching their peak around November, before pollen counts gradually decline through January and February. Neighboring parts of the region typically see this same sequence with only minor timing shifts.

Does pollen in Hoffman 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 Hoffman 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 Hoffman, 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. |
