Local Environmental Conditions
Here, within the neighborhood, river oak crowds the water's edge here, a well-known contributor to local casuarina pollen counts. Here, near this part of town, eucalypt dominating the treeline with wattle scattered through it, both contributing to the season's pollen load. Local wind exposure and land use can shift the exact mix slightly from block to block.
The waterside river oak is consistently first to release pollen each year, arriving ahead of the rest of the season, cresting around mid-winter. Eucalypt and wattle in the nearby woodland follow through late winter and early spring, usually peaking from August into October. Grass pollen rises through spring toward a November high point, then holding at a high level well into January before easing off.

Does pollen in Ourimbah 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 Ourimbah 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 Ourimbah, 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. |
