Local Environmental Conditions
The waterway's edge supports river oak, a species whose fine pollen travels well beyond the immediate bank, a short distance from here. Nearby, just outside the immediate area, eucalypt and wattle growing together, with wattle's fine pollen especially potent during its short flowering window. A nearby park's turf and plane trees layer additional pollen onto the seasonal grass count; this sits in the wider area.
River oak along the water gets the season underway before other species, topping out well before most other trees start releasing pollen, around July and August. Eucalypt and wattle nearby take over the pollen calendar through late winter, typically landing in August and September. Grass pollen rises through spring toward a November high point, before pollen counts gradually decline through January and February.

How often is the Mosman Park pollen forecast updated?

Does pollen in Mosman Park 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 Mosman Park 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 Mosman Park, 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. |
