Local Environmental Conditions
Water here is bordered by river oak, a casuarina species known for prolific, far-carrying pollen, just outside the immediate area. Here, close to home here, forest where eucalypt and wattle share the canopy and margins, wattle driving most of the seasonal pollen spike. Maintained parkland where turf grass and ornamental plane trees add to the local pollen mix; this sits a short distance from here.
Near the bank, river oak leads the seasonal calendar, topping out well before most other trees start releasing pollen, around July and August. Eucalypt and wattle in the woodland come next, as wattle bursts into flower, peaking as wattle comes into full flower, generally August into September. Grass pollen climbs toward a November peak, with levels staying elevated into the new year before finally easing off.

Are pollen levels in West Pymble 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 West Pymble, 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. |
