Local Environmental Conditions
Located just around the area, this area has river oak grows along the bank here, releasing fine wind-borne pollen typical of casuarina species. A stand of eucalypt with wattle through the understorey, wattle ranked among the region's sharpest allergens, not far from here. Year-to-year swings in rainfall and wind can shift this picture somewhat either way.
In Charlie's Flat Campground, water-edge river oak is usually the first allergenic tree active here, usually the first pollen source active, peaking sometime in July or August. Grass pollen counts rise through spring, reaching their peak around November, before pollen counts gradually decline through January and February. This general pattern holds fairly steady across the surrounding region from year to year.

Does pollen in Nanga Brook 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 Nanga Brook 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 Nanga Brook, 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. |
