Local Environmental Conditions
Located just outside the immediate area, this area has water here is bordered by river oak, a casuarina species known for prolific, far-carrying pollen. Mown grass and planted plane trees in a nearby park, adding to the seasonal pollen mix; this sits in the vicinity. Year-to-year swings in rainfall and wind can shift this picture somewhat either way.
Near the bank, river oak leads the seasonal calendar, starting well before the main spring rush, topping out around September. Spring brings rising grass pollen that crests in November, and remaining a significant allergen right through summer until it eases in February. Daily pollen counts published for the wider region track this same seasonal rhythm closely.

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. |
