Local Environmental Conditions
Here, in the vicinity, water here is bordered by river oak, a casuarina species known for prolific, far-carrying pollen. This area, in the vicinity, has a mix of eucalypt and wattle, wattle in particular a notorious trigger for hay fever across southern Australia. Located within the local area, this area has a nearby park's turf and plane trees layer additional pollen onto the seasonal grass count.
The bank's river oak kicks off the pollen season ahead of the rest, peaking in mid-winter through September. As spring approaches, eucalypt and wattle in the nearby woodland become the dominant source, cresting around August and September in the year's sharpest tree-pollen spike. As spring turns to summer, grass pollen rises toward its November high, before pollen counts gradually decline through January and February.

Does pollen in Chatswood 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 Chatswood 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 Chatswood, 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. |
