Local Environmental Conditions
Eucalypt dominating the treeline with wattle scattered through it, both contributing to the season's pollen load; this sits just outside the immediate area. This area, close to home here, has a nearby park's turf and plane trees layer additional pollen onto the seasonal grass count. Local readings for the surrounding area tend to follow this same general pattern.
Woodland eucalypt and wattle pick up the pace next, through late winter into spring, building to its sharpest point across August and September. As spring turns to summer, grass pollen rises toward its November high, with levels staying elevated into the new year before finally easing off. Local weather swings can shift these windows slightly, but the overall order tends to hold.

How often is the Forest Hill pollen forecast updated?

Does pollen in Forest Hill 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 Forest Hill 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 Forest Hill, 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. |
