Local Environmental Conditions
This area, close to home here, has river oak grows along the bank here, releasing fine wind-borne pollen typical of casuarina species. Woodland where eucalypt stands alongside wattle, the latter especially aggressive as an allergen when in full flower, in the wider area. Local readings for the surrounding area tend to follow this same general pattern.
Water-edge river oak is usually the first allergenic tree active here, arriving ahead of the rest of the season, cresting around mid-winter. Eucalypt and wattle nearby take over the pollen calendar through late winter, peaking as wattle comes into full flower, generally August into September. Grass pollen builds through spring and peaks in November, before continuing at a lower but still notable level through January and February.

Does pollen in Berowra Waters 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 Berowra Waters 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 Berowra Waters, 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. |
