Local Environmental Conditions
Here, close to home here, water here is bordered by river oak, a casuarina species known for prolific, far-carrying pollen. A canopy of eucalypt threaded with wattle, wattle chief among them for allergenic potency here; this sits just outside the immediate area. Located in the vicinity, this area has a green space of mown lawn and planted plane trees, both feeding into local pollen counts.
Near the bank, river oak leads the seasonal calendar, peaking in mid-winter through September. The area's eucalypt and wattle trees pollinate through late winter and early spring, typically the year's sharpest tree-pollen spell, centered on wattle's flowering in August and September. By late spring, grass pollen is climbing steadily toward a November high point, before staying elevated through the summer months into late January.

How often is the Sydney pollen forecast updated?

Does pollen in Sydney 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 Sydney 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 Sydney, 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. |
