Local Environmental Conditions
Here, close to home here, a stand of river oak lines the water, a reliable source of casuarina pollen through the warmer months. Located just around the area, this area has a stand of eucalypt with wattle through the understorey, wattle ranked among the region's sharpest allergens. Local wind exposure and land use can shift the exact mix slightly from block to block.
The bank's river oak kicks off the pollen season ahead of the rest, reaching its high point sometime in late winter or early spring. By late winter, eucalypt and wattle in the woods take over, cresting around August and September in the year's sharpest tree-pollen spike. As spring turns to summer, grass pollen rises toward its November high, then persisting at a reduced but still meaningful level into the new year.

How often is the Ourimbah pollen forecast updated?

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. |
