Local Environmental Conditions
Located just outside the immediate area, this area has a waterway lined with river oak, a wind-pollinated species and one of the more potent allergen sources along Australian creeks and rivers. A canopy of eucalypt threaded with wattle, wattle chief among them for allergenic potency here; this sits just outside the immediate area.
The waterside river oak is consistently first to release pollen each year, usually the first pollen source active, peaking sometime in July or August. Eucalypt and wattle in the woodland come next, as wattle bursts into flower, cresting around August and September in the year's sharpest tree-pollen spike. Grass pollen takes over next, building to a peak around November, with the season extending well into summer before finally winding down in February.

When is pollen season in Sydney?
How often is the Sydney pollen forecast updated?
The Sydney pollen forecast is updated four times daily. See the timestamp below for the most recent update.
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. |
